Welcome from the Conference Chairman
Dear Colleagues,
I am pleased to welcome you to Tsukuba for the 1st International
Beam Instrumentation Conference, IBIC2012, on behalf of theProgram Committee. The conference is hosted by the High Energy
Accelerator Research Organization (KEK) and supported by oursponsors and venders. In 2010, representatives from the Americas,
Europe, and Asia agreed to merge the two regional workshops, BIW in
North America and DIPAC in Europe, and combine with a
newly-established Asian regional committee to create a new
International Beam Instrumentation Conference, IBIC, from 2012. Thisis a great milestone for the world beam instrumentation community,
and it reflects the maturity of international collaboration in the field of
beam instrumentation for accelerators. IBIC will be dedicated to
exploring the physics and engineering challenges of beam diagnostic
and measurement techniques for charged particle accelerators
worldwide.
The venue for IBIC2012 is the Tsukuba International Congress
Center, a modern, dedicated conference facility, situated in the heartof the city. Tsukuba is located 60 km east of Tokyo, and is Japan's
largest research city with more than 300 research institutes. Tsukuba
is also one of world's key sites for basic research in science andtechnology.
The IBIC2012 program includes three tutorials on selected topics,
11 invited talks, 18 contributed talks, and poster sessions. There are
24 vendor exhibits from Monday through Wednesday. The conference
Banquet will be held in the traditional Japanese Ryokan (Hotel)"Edoya," on Mt. Tsukuba. A tour of the accelerator facilities at KEK and
J-PARC is scheduled for on Thursday afternoon. In addition, there is a
special social event, a one day tour to Nikko on Friday. Nikko is a
popular destination for Japanese and international tourists, withshrines and temples on the UNESCO World Heritage List.
The Program Committee would sincerely like to give thanks for thegenerous support of KEK, ACFA, the Tsukuba Tourist and Convention
Association, Tsukuba EXPO'85 Memorial Foundation, Foundation forHigh Energy Accelerator Science, and JACoW. A special "Thank you"must also be expressed to the members of the Local Organizing
Committee, whose enthusiastic and outstanding efforts made IBIC
2012 a reality
Sincerely,
Toshiyuki Mitsuhashi

Monday Session A, 8:30 – 10:00
Chair: Toshiyuki Mitsuhashi (KEK)
MOIA01 Accelerator Projects at KEK - Katsunobu Oide (KEK, Ibaraki)This is a short talk to introduce accelerator projects at KEK
including the Super B-Factory (SuperKEKB), Photon Factory(PD/PF-AR) and the high-intensity proton machine J-PARC.
Some R&D efforts for future such as the International Linear
Collider (ILC/STF/ATF) and the Energy Recovery Linac will bealso overviewed. It may briefly mention on critical issues related
to beam instrumentation for each project.
MOIA02 Progress of Beam Instumentation in J-PARC Linac - Akihiko Miura(JAEA/J-PARC, Tokai-mura)

J-PARC, one of the high intensity proton accelerators, achieved
the output power of 300 kW at the downstream rapid cycling
synchrotron with a beam energy of 181 MeV and a beam
current of 15 mA. When an upgrade of an ion source which canprovide 50 mA and the installation of the additional
acceleration cavities for the energy upgrade up to 400 MeV arecompleted, output power can reach 1MW. To meet with therequirements of the high intensity beam diagnostics, we prepare
several measures against high intensity proton related issues.
The following subjects have been reported among many
subjects: development of strip-line type beam position monitors,
beam current monitors, phase monitors and transverse profile
monitors. And the subjects of the beam diagnostic for theenergy upgraded linac including the longitudinal beam profile
monitor and the developing laser based profile monitor will bementioned. A big earthquake occurred on May 11, 2011. We
successfully recovered to have commercial operation, but apartial recovery is still undergoing. Influence of the quake on the
J-PARC linac is also mentioned.

upgraded to SuperKEKB. The design luminosity of 8 x 10^35/cm^2/s will be achieved using beams with low emittance ofseveral nm and doubling beam currents to 2.6 A in the electron
ring (HER) and 3.6 A in the positron ring (LER). A beam position
monitor (BPM) system of HER and LER will be equipped withsuper-heterodyne detectors, turn by turn log ratio detectors
with fast gates to measure optics parameters during collision
operation and detectors of BPMs near the collision point (IP) for
orbit feedback to maintain stable collision. New X-ray beamprofile monitors based on the coded aperture method will be
installed aiming at bunch by bunch measurement of the beamprofile. A large angle beamstrahlung monitor detecting
polarization of the synchrotron radiation generated bybeam-beam interaction will be installed near IP to obtain
information about the beam-beam geometry. The bunch bybunch feedback system will be upgraded using low noise
frontend electronics and new 12 bits iGp digital filters. An
overview of beam instrumentation of SuperKEKB rings will begiven in this paper.
MOCB02 A Generic BPM Electronics Platform for European XFEL, SwissFEL
and SLS - Boris Keil, Raphael Baldinger, Robin Ditter, Waldemar

Koprek, Reinhold Kramert, Goran Marinkovic, Markus Roggli,Markus Stadler, Daniel Marco Treyer (Paul Scherrer Institut,
Villigen)

PSI is currently developing the 2nd generation of a genericmodular electronics platform for linac and storage ring BPMs
and other beam diagnostics systems. The first platform,
developed in 2004 and based on a generic digital back-end
with Xilinx Virtex 2Pro FPGAs, is currently used at PSI for proton
accelerator BPMs, resonant stripline BPMs at the SwissFEL test
injector facility, and a number of other diagnostics and detector
systems. The 2nd platform will be employed e.g. for European
XFEL BPMs, a new SLS BPM system, and the SwissFEL BPM
system. This paper gives an overview of the architecture,features and applications of the new platform, includinginterfaces to control, timing and feedback systems. Differences
and synergies of the different BPM and non-BPM applications
will be discussed.

commonly used high precision current monitor in modern
particle accelerators including Shanghai Synchrotron Radiation
Facility (SSRF). Three types of noise have been observed in the
output signal of the DCCT in the storage ring of SSRF: powerline noise, beam current related narrow band noise and randomsquare wave noise from nowhere. This article will discuss thenoise removal algorithms in SSRF and the performance of the
DCCTs afterwards.
MOCB04 Vertical Emittance Measurements using a Vertical Undulator -Kent Peter Wootton, Roger Paul Rassool, Geoffrey Taylor (The
University of Melbourne, Melbourne), Mark James Boland,
Bruce Cowie, Rohan Dowd (ASCo, Clayton, Victoria), Yannis
Papaphilippou (CERN, Geneva)

With vertical dimensions of several microns, direct
measurement of beam size is approaching diffraction limits ofvisible light and hard x-ray emittance diagnostics. We report on
the development of a new vertical electron beam size
measurement and monitoring technique which utilizes a verticalundulator. An APPLE-II type undulator was phased to produce ahorizontal magnetic field, deflecting the electron beam in thevertical plane. The measured ratios of undulator spectral peakheights are evaluated by fitting to simulations of the apparatus.
Vertical electron beam emittances of several picometres havebeen observed at the Australian Synchrotron storage ring. With
this apparatus immediately available at most existing electron
and positron storage rings, we find this to be an appropriate andnovel vertical emittance diagnostic.

Michael Gerard Billing (CLASSE, Ithaca, New York), Pavel
Karataev (JAI, Egham, Surrey)

Diffraction Radiation (DR) is produced when a relativistic
charged particle moves in the vicinity of a medium. The electricfield of the charged particle polarizes the target atoms whichthen oscillate, emitting radiation with a very broad spectrum.
The spatial-spectral properties of DR are sensitive to a range of1917

Monday

electron beam parameters. Furthermore, the energy loss due to
DR is so small that the electron beam parameters areunchanged. Therefore DR can be used to develop non-invasive
diagnostic tools. The aim of this project is to measure thetransverse (vertical) beam size using incoherent DR. To achieve
the micron-scale resolution required by CLIC, DR in the UV and
X-ray spectral-range must be investigated. During the next few
years, experimental validation of such a scheme will be
conducted on the CesrTA at Cornell University, USA. Here we
present the current status of the experiment preparation.
MOIC02 Electron Beam Diagnostic System for the Japanese XFEL, SACLA -Hirokazu Maesaka, Hiroyasu Ego, Chikara Kondo, Takashi
Ohshima, Yuji Otake, Hiromitsu Tomizawa (RIKEN SPring-8
Center, Sayo-cho, Sayo-gun, Hyogo), Shin-ichi Matsubara(JASRI/SPring-8, Hyogo), Takahiro Matsumoto, Kenichi
Yanagida (JASRI/SPring-8, Hyogo-ken)An x-ray free-electron laser (XFEL) based on self-amplified
spontaneous emission (SASE) requires a highly brilliant electron
beam. The Japanese XFEL facility, SACLA, requires a normalized
emittance less than 1 mm mrad and a peak current more than 3
kA. To achieve this high peak current, 1 A beam with 1 ns
duration from a thermionic electron gun is compressed down to
30 fs by means of a multi-stage bunch compressor system.
Therefore, the beam diagnostic system for SACLA was designed
for the measurements of the emittance and bunch length ateach compression stage. We developed a high-resolution
transverse profile monitor and a temporal bunch structure
measurement system with a C-band rf deflector cavity etc. In
addition, precise overlapping between an electron beam andradiated x-rays in the undulator section is necessary to ensure
the XFEL interaction. Therefore, we employed a C-band
sub-micron resolution RF-BPM to fulfill the demanded accuracyof 4 um. The beam diagnostic system surely contributed to thefirst x-ray lasing at a wavelength of 1.2 Angstrom. We present a
design strategy of the whole beam diagnostic system and theachieved performance for each monitor.

University of Tokyo, Tokyo)

Pilot user experiments via the seeded FEL have been
demonstrated at the Prototype Test Accelerator (VUV-FEL),
SPring-8 from July, 2012. A precise measurement of theelectron bunch charge distribution (BCD) is crucial key to keep
spatial and temporal overlaps between high-order harmonic(HH) laser pulses and electron bunches. R&D of the 3D-BCD
monitor with a single-shot detection has been extensively
promoted at SPring-8. The monitor adopts a spectral decoding
based Electro-Optic (EO) sampling technique that is
non-destructive and enables real-time reconstruction of the
3D-BCD with a temporal resolution of 30- to 40-fs (FWHM). So
far, such EO sampling based BCD monitors have beendeveloped by utilizing inorganic EO crystals such as ZnTe andtheir temporal resolutions are limited to ~130 fs (FWHM). As apart of this project, the first BCD measurement with an organic
EO crystal DAST has been successfully demonstrated at thefacility. Signal intensities, temporal resolutions and radiation
related issues via both ZnTe and DAST are discussed.
MOCC04 Improvement of Screen Monitor with Suppression of
Coherent-OTR for SACLA - Shin-ichi Matsubara, Yuji Otake(RIKEN/SPring-8, Hyogo), Hirokazu Maesaka (RIKEN Spring-8
Harima, Hyogo), Shinobu Inoue (SES, Hyogo-pref.)

The construction of SACLA (SPring-8 Angstrom Compact freeelectron LAser) was already completed and it is under operation.
A screen monitor (SCM) system has been developed and was
installed in order to obtain a direct image of a transverse beamprofile with a spatial resolution of about 10 um, which is
required to investigate electron-beam properties, such as abeam emittance. The SCM originally has a stainless steel target
as a OTR radiator or a Ce:YAG crystal as a scintillation target. At
the beginning of the SACLA operation, strong coherent OTR(COTR), which made an incorrect beam profile, was observed
after bunch compressors. In order to suppress the COTR on the
SCM, the stainless steel target was replaced to the Ce:YAG
scintillation target. Since the COTR was still generated from theCe:YAG target, a spatial mask was employed. The mask was
mounted on the center of the optical line of the SCM, because
the COTR light is emitted forward within ~1/γ radian, while thescintillation light has not angular dependence. Clear beam

profiles with a diameter of a few tens of micro-meter are
observed by means of the SCMs with this simple improvement.

MOPA01 Final Design of the Striplines for the Extraction Kicker of the CLIC
Damping Rings - Carolina Belver-Aguilar, Angeles Faus-Golfe(IFIC, Valencia), Michael John Barnes (CERN, Geneva), Ivan
Podadera, Fernando Toral (CIEMAT, Madrid)

Pre-Damping Rings (PDR) and Damping Rings (DR) are required
to reduce beam emittance and, therefore, to achieve theluminosity requirements for the CLIC main linac. Kicker systems
will be used to inject and extract the beam from the PDRs andDRs: the most challenging of these is the DR extraction kicker
system. In this paper we present results from a comprehensive
set of 3D analyses of the striplines for the DR extraction kicker,
including studies of tapering of the electrodes, an estimate of
the power loss in the coaxial feedthroughs and beam coupling
impedance calculations for a tapered beam pipe. Furthermore
the required mechanical tolerances for the stripline are alsopresented. Prototype striplines will be manufactured, to thespecified tolerances, and will be available for tests from
December 2012: it is planned to measure field stability, field
homogeneity and beam coupling impedance. Measurements
will be carried out in the laboratory and in both the ALBA andATF2 facilities.
MOPA02 270 degree Electron Beam Bending System using Two Sector
Magnets for Therapy Application - Sanjay Daga Dhole, Shahzad

Akhter, Vasnat Nagesh Bhoraskar, Bhushankumar Jagnnath Patil(University of Pune, Pune), Sharad Trayambak Chavan,

Mumbai)

The 270 degree doubly achromatic beam bending magnet
system using two sector magnets has been designed mainly fortreating cancer and skin diseases. The main requirements of thedesign of two magnet system is to focus an electron beam
having a spot size less than 3 mm X 3 mm, energy spread within
3% and divergence angle <= 3 mrad at the target. To achievethese parameters the simulation was carried out using
Lorentz-3EM software. The beam spot, divergence angle andenergy spread were observed with respect to the variation inangles of sector magnets and drift distance. From the simulated

results, it has been optimized that the first and second magnet
has an angle 195 degree and 75 degree and the drift distance
64 mm. It is also observed that at the 1396, 2878 and 4677
A-turn, the optimized design produces 3324, 6221 and 9317
Gauss of magnetic field at median plane require to bend 6, 12
and 18 MeV electron respectively. The output parameters of the
optimized design are energy spread 3 %, divergence angle ~ 2.8
mrad and spot size 2.6 mm.
MOPA03 Beam Diagnostics for PAL-XFEL - Changbum Kim, Hyojin Choi,

Jae-Young Choi, Do Tae Kim, Eun Hee Lee, Byoung Ryul Park,
Jong Chel Yoon (PAL, Pohang, Kyungbuk)

Pohang Accelerator Laboratory started its XFEL program from2011. The XFEL project in Pohang Accelerator Laboratory (PAL)
requires low beam-emittance, ultra-short bunch length, highpeak current, high stability of beam energy. Therefore, beamdiagnostics for SASE XFEL should be, focused on attaining

MOPA04 An Electron Beam Profile Monitor for the Race-track Microtron -Sanjay Daga Dhole, Vasnat Nagesh Bhoraskar, Bhushankumar
Jagnnath Patil, Ninad S. Shinde (University of Pune, Pune)

In electron irradiation experiments on materials such as
semiconductors, solar cells etc., an uniformity and the charge
distribution in the electron beam is very important. Therefore,
an electron beam current monitor and its electronic systemhave been designed and built to measure the distribution of abeam current either in the horizontal or vertical direction alongwith the beam dimensions. To obtain X-Y beam profile, a special
type of Faraday Cup was designed which mainly consists ofcharge collecting electrodes made up of thin copper strips.
Each strip having dimensions 0.5 mm wide, 4 mm thick and 20
mm long were fixed parallel to each other and separation
between them was ~ 0.5 mm. This multi electrode Faraday was
mounted at the extraction port of the Race Track Microtron,
where 1 MeV electron beam allowed to fall on it. The beamcharacterization in the form of current and uniformity were
measured. The current from each strip were measured using anelectronic circuit developed based on the multiplexing principle.

MOPA05 X-ray Diagnostic of High-current Low-energy Electron Beam in
Plasma - Sergiy Cherenshchykov, Valentin Kotsubanov(NSC/KIPT, Kharkov)

Low-energy high-current electron beams are used in a novel
technology for surface modification of metallic materials.
Propagation high current electron beam in plasma give
possibility for much current increasing. Direct diagnostic by a
Faraday cup in plasma is incorrect. Therefore we used for beamdiagnostic X-ray radiation from a metal target. The electron
beam was creating by a cold-cathode magnetron injection gun.
The gun voltage was nearly 20 kV. The target current was up to
20 kA. We observed X-ray radiation by its transformation invisible light. Plastic scintillators were used for high time
resolution. A cross section of beam and time dependences was
obtained too. For time dependence resolution was used digital
oscillograph Tektronix. Photomultiplier tubes were used for lightdetection. Their signal was write together with target current by
the Faraday cup and visible light emission. We observed inoscillograms X-ray radiation without target current and target
current without X-ray radiation with duration up several
microseconds. The diagnostic method will be use for next
improvement cold-cathode magnetron injection gun as sourceof low-energy high-current electron beam.
MOPA06 VIMOS, New Capabilities for a Dedicated Optical Safety System -Knud Thomsen (Paul Scherrer Institut, Villigen)

VIMOS is a dedicated safety system developed at the Spallation
Neutron Source SINQ at the Paul Scherrer Institut, PSI, in
Switzerland. VIMOS very directly monitors the correct current
density distribution of the proton beam on the target bysampling the light emitted from a glowing mesh heated by thepassing protons. The design has been optimized for obtaining
maximum sensitivity and timely detection of beam irregularities
relying on standard well-proven components. Recently it has
been demonstrated that technical boundary conditions likeradiation level and signal strength should allow for upgrading
the system to a sensitive diagnostic device delivering
quantitative and image-resolved values for the proton current
density distribution on the SINQ target. By determining thetemperature of the glowing mesh from the signals in two

NIRS - Satoru Hojo, Akira Goto, Toshihiro Honma, Ken Katagiri,

Akinori Sugiura (NIRS, Chiba-shi), Yuichi Takahashi (AEC, Chiba)

The small cyclotron HM-18 of the National Institute ofRadiological Sciences (NIRS) has been operated for use in RI
production since 1994. The HM-18 allows us to accelerate
protons and deuterons at fixed energies of 18 and 9 MeV,
respectively. It has four trim coils for generation of theisochronous fields. Until recently, currents of the four trim coils
had been adjusted only by monitoring the output beam
intensity. In order to exactly produce the isochronous fields, a
new phase probe has been installed in the HM-18. The phaseprobe has a simple structure in which four copper electrodeplates of 60 mm x70 mm in area are glued to a copper baseplate with a polyimide insulator between them. The thicknessesof the copper plates and the polyimide are 0.1 mm. This
structure has an advantage that it can be easily installed in thecyclotron; only one part of a pair of upper and lower electrodes,
which is usually adopted, is simply attached on the surface ofthe (lower) sector pole. The development of the phase probe
and some results of a preliminary beam test using it arereported.

Wall current monitors (WCM) for rf system commissioning are
installed in the J-PARC synchrotrons, the RCS and the MR. The
WCM signals are used as the input of the beam loading
compensation system, and also used diagnosis to adjust the rf
system parameters. Since the rf and beam frequency is in therange of a few MHz, direct measurement of the WCM signals is
possible. For the diagnosis, the WCM signals are taken by an

LLRF control system, and slices of the WCM waveform withlengths of the revolution periods are generated. By stacking theslices, one can get a mountain plot, which shows motions ofbunches and variations of the bunch shapes. Also, time
variations of the bunching factor, which are important for
acceleration of high intensity proton beams, are obtained. The
harmonic analysis is performed on the WCM signal and thecavity voltage monitor signal. By using complex amplitudes ofthem, one can calculate the impedance seen by the beam. In
this presentation, we show examples of the analyses describedabove. The rf parameters for high intensity beams have beensuccessfully adjusted by using these analyses.
MOPA09 Comparison of Three Different Concepts of High Dynamic Rangeand Dependability Optimised Current Measurement Digitisers for

adaptive current to frequency converter implemented in an
ASIC. The basic parameters of the circuit are discussed andcompared with measurements. Several measures are taken to
harden both circuits against single event effects and to makethem tolerant for operation in radioactive environments. The
third circuit is based on a fully differential integrator forenhanced dynamic range, where laboratory and test installation

MOPA11 The Linearity Calibration of the PMT Using Synchrotron Light -Chang Liu, Yongbin Leng, Luyang Yu (SINAP, Shanghai)

A fiber-based Cerenkov beam loss monitor has been widelyused in the world for FEL facilities to monitor electron beamlosses. As a key component, Photomultiplier (PMT) is employed
to detect the Cerenkov light emitted by the secondary charge
particles. The linearity of the PMT has to be calibrated precisely
due to its strong impact to the position accuracy and sensitivityof the whole system. Synchrotron radiation is therefore a perfectcalibration source with fine linearity and large intensity scale.
The preliminary calibration result of PMT using synchrotron lightat SSRF will be presented in this paper.

An Application Specific Integrated Circuit (ASIC) has been
designed and fabricated to provide a compact solution todigitize current signals from ionization chambers and diamonddetectors, employed as beam loss monitors at CERN and several
other high energy physics facilities. The circuit topology has
been devised to accept positive and negative currents, to have awide dynamic range (above 120 dB), withstand radiation levels
over 100kGy and offer different modes of operation, covering abroad range of applications. Furthermore, an internalconversion reference is employed in the digitization, to provide

systematic stepper motor movements of the XBPM or wellcontrolled electron beam displacements to measure theresponse of the XBPM. For each Insertion Device gap it isrequired to repeat this in order to build up a complete set ofscale factors covering all possible operating conditions.
Elliptically Polarising Undulators further complicate matters byhaving multiple operating modes which would require multidimensional lookup tables. Presented in this paper is a method

We have been developing three dimensional bunch charge
distribution (3D-BCD) monitor for FEL seeded with high-orderharmonic (HH) pulse. 3D-BCD is based on EO-samplingtechnique with multiple EO crystal detectors in the manner ofspectral decoding. Using this 3D-EO sampling technique, thepositioning and timing of electron bunch is obtained inreal-time with non-destructive measurement. For obtaining thehigh temporal resolution, an octave broadband probe laser withlinear chirp rate of 1 fs/nm is required. We are developing an
EO-probe laser pulse with ~10 µJ pulse energy and the
bandwidth over 300 nm (FWHM). For meet these bandwidthand pulse energy, this EO-probe pulse is using a
supercontinuum generated by photonic crystal fiber (PCF) andamplified with optical parametric amplification (OPA). Especially,
for amplification with maintaining octave bandwidth,non-collinear OPA (NOPA) using BBO crystal and a pump sourcewith a wavelength of 450 nm are adopted. The EO-probe pulse
energy of 10 µJ provides for high S/N ratio to each detector andthe bandwidth of 300 nm with 300 fs pulse duration allows themeasurement for the 30 fs electron bunch duration (FWHM).

however, not to have the capacitors. Therefore we havesufficient signal intensity from low intensity beams of the initial
beam commissioning, but too large from the design intensity
beam. The processing circuits (BPMC) have to accommodate
those output signals from high intensity beams. We are adding
the attenuator-LPFs just before the BPMC. This paper will

Mathematica program is designed to monitor statisticallyindividual bunches (spacing 61.54ns) as well the train as awhole (up to 1625 bunches), allowing the study of jitter andposition stability of the beam through the arc. The ALICE arc has

achieved through a separate dedicated bunch compressor
chicane. The arc incorporates two sextupoles for correcting
non-linear longitudinal matrix terms and experimental evidence
suggests that the off-centred beam in the sextupoles breaks thelinear isochronicity. We present some beam measurement

IBFB will measure the positions of each bunch in the bunchtrain, and apply intra-train feedback corrections with fastkickers, in addition to a feed-forward correction forreproducible trajectory perturbations. By achieving a feedback
loop latency in the order of one microsecond, the IBFB willallow the beam position to converge quickly to the nominal
orbit as required for stable SASE operation. The latest

SuperKEKB Accelerator - Makoto Tobiyama, John Walter

Flanagan (KEK, Ibaraki)

A High-speed digital signal memory has been developed for thebunch current and oscillation recorder for SuperKEKB. The
memory consists of an 8-bit ADC and a FPGA daughter cardwith Spartan6 and DDR2 memories commercially available on adouble width VME card. The block-RAM on the FPGA is used totransfer bunch current data with low latency for prompt bunch
current measurements, and the large DDR2 memory is used forlong-duration position recording, such as post-mortem bunch
oscillation recording. The performance of the board, including
data transfer rate, will be presented.
MOPA37 Reliable Beam-Intensity Control Technique at the HIMAC
Synchrotron - Kota Mizushima, Takuji Furukawa, Yousuke Hara,

Yoshiyuki Iwata, Ken Katagiri, Koji Noda, Shinji Sato, Toshiyuki
Shirai (NIRS, Chiba-shi)

The carbon-ion beam is slowly extracted from the Heavy Ion
Medical Accelerator in Chiba (HIMAC) synchrotron using thethird-order resonance with the RF-knockout method forscanned carbon-ion therapy. However, an overshoot of thebeam spill at the start of extraction is often induced by a slightvariation of the beam emittance in operation cycles. It brings
dose hot spot inside the target volume, because the tolerable
beam-intensity in scanning irradiation is low. We have added
short extraction, called preliminary extraction, before irradiationin order to remove the uncontrollable spilled particles. During
preliminary extraction, it is necessary to prevent the beam
delivering to the patient. Therefore, a fast beam shutter onwhich an ionization chamber is mounted was developed, and it
was installed in the extraction line. The fast shutter enables us
to switch from preliminary extraction to irradiation within 100
ms, and the reliability of the beam-intensity control system wasdrastically improved by the preliminary extraction technique.

intensity-dependent collective effects that arise because of theelectromagnetic wake fields generated by the beam as it
interacts with its environment. These instabilities limit the highcurrent operation in the accelerator and degrade theperformance of synchrotron radiation beam. Indus-2 is asynchrotron radiation source at RRCAT, Indore having design
beam current of 300 mA and 2.5 GeV beam energy. Beamintensity signal obtained from wall current monitor (WCM) is
used to measure the longitudinal coupled bunch modes (CBM).
To study the beam instabilities, an automated software has
been developed which acquires the beam intensity spectrum formeasurement of coupled bunch modes. The software has
option of complete CBM scan, scanning near the significant RF
cavity higher order modes (HOM) and scanning of user-selectedmodes. The scanning time for complete 291 modes is ~5
minutes. In this paper, we describe the measurement system,features of the developed software and some measurement
results on Indus-2 machine.
MOPA39 Introduction of Photon BPMs in SOLEIL Global Orbit Feedback
Systems - Nicolas Hubert, Lodovico Cassinari, Jean-Claude

Denard, Laurent Stanislas Nadolski (SOLEIL, Gif-sur-Yvette)

SOLEIL global orbit feedback systems (slow and fast), based on
122 Electron Beam Position Monitor (eBPM) readings, are in
operation since 2008 and give very satisfying performances(0.1Hz-500Hz vertical noise < 300 nm, long term (8h) drifts <1µm RMS). Nevertheless, in SOLEIL layout, magnetic elements(quadrupoles and sextupoles) are located between dipoles andtheir closest eBPMs. For that reason, Photon Beam Position
Monitors (XBPMs) in the dipole beamline frontend give
additional information that is useful to stabilize better thesource point in the dipole. XBPMs provide also a better angularmeasurement resolution as they are located at 4 meters fromthe source point. Results presented in this papers show thatvertical stability on bending magnet beamlines can be improvedby including their XBPM measurements in global orbit feedback
systems. In a first time XBPMs have been introduced in the Slow
Orbit Feedback system (SOFB) that corrects the orbit with arepetition rate of 0.1Hz. In a second time XBPMs will be
introduced in the Fast Orbit Feedback system (FOFB) running at
a repetition rate of 10 kHz.

MOPA40 High Frequency Response of Accelerator Vacuum Chambers and
Implications for Orbit Feedback Systems - Boris Podobedov (BNL,

Upton, Long Island, New York)

Understanding the response of conducting accelerator vacuum
chambers to external AC magnetic field is important for many
accelerator applications, where the particle beam is dynamicallydriven with magnets external to the chamber. For instance,
efficient orbit feedback system design requires detailed
knowledge of the chamber transfer function at the locations ofcorrector magnets, which in general depends on the chambermaterial, cross-sectional shape and thickness. In practicallyinteresting cases, the chamber response is influenced by both
eddy currents and the skin effect, which are often accounted forrather crudely when modeling the system. This paper presents
new analytical results for transfer functions through arbitrary
shaped vacuum chambers; compares them with themeasurements for the present NSLS rings and discusses theimplications for the future NSLS-II orbit feedback systems.
MOPA42 Measurements of Martin-Puplett Interferometer Limitations using
Blackbody Source - Pavel Evtushenko, J. Michael Klopf (JLAB,

Newport News, Virginia)

Frequency domain measurements with Martin-Puplettinterferometer is one of a few techniques capable of bunch
length measurements at the level of ~ 100 fs. As the bunch
length becomes shorter, it is important to know and be able tomeasure the limitations of the instrument in terms of shortest
measurable bunch length. In this paper we describe experimentof using blackbody source with the modified Matrin-Puplettinterferometer that is routinely used for bunch length
measurements at the JLab FEL, as a way to estimate the shortest,
measurable with the device, bunch. The limitation comes fromhigh frequency cut-off of the presently used wire-grid polarizer
and is estimated to be 50 fs RMS. The measurements are madewith the same Golay cell detector that is used for beammeasurements. We demonstrate that, even though theblackbody source is many orders of magnitude less bright thanthe coherent transition or synchrotron radiation, it can be used
for the measurements and gives a very good signal to noise ratio
in a combination with lock-in detection. We also compare themeasurements made in air and in vacuum to show the verystrong effect of the atmospheric absorption.

MOPA43 RF Front-end for High Bandwidth Bunch Arrival-time Monitors in
Free-Electron Lasers at DESY - Andreas Penirschke, Aleksandar

Schlarb, Cezary Sydlo (DESY, Hamburg), Sascha Schnepp (IFH,

Alexander Kuhl (Uni HH, Hamburg)

The Free-Electron Laser in Hamburg FLASH is equipped with
Bunch Arrival-time Monitors (BAMs) that use an electro-opticaldetection scheme to modulate the intensity of the femtosecond
laser pulse train with the pickup signals (*). The achieved
resolution of the existing BAMs are less than 10 fs for bunchcharges higher than 500 pC. For lower bunch charges the time
resolution drops significantly. Increased demands for low bunchcharge operation modes of 20 pC and less at FLASH II and theEuropean X-ray Free-Electron Laser XFEL require an upgrade ofthe existing beam diagnostic equipment. High bandwidth BAMs
with newly developed cone-shaped pickups (**) promise sub-10
fs time resolution for both, the high and low bunch charge
operation mode. This paper addresses the RF signal path of thehigh bandwidth BAMs for FLASH II and XFEL. It comprises
radiation resistant coaxial cables, combiners and limiters up to afrequency of 40 GHz from the pickup electrodes to theElectro-optical Mach-Zehnder type modulator (EOM). Detailed
investigations of the signal path using measurements andsimulations with AWR Microwave Office allows for a goodprediction of the signal quality and shape at the EOM.
MOPA44 Coherent Optical Transition Radiation at the SwissFEL Injector
Test Facility - Bennie Smit, Masamitsu Aiba, Simona Bettoni,

Bolko Beutner, Rasmus Ischebeck, Gian Luca Orlandi, Eduard
Prat, Leonid Rivkin, Thomas Schietinger, Volker Schlott (PaulScherrer Institut, Villigen)

SwissFEL uses magnetic dispersive sections for bunch
compression, which may cause micro-bunching within theelectron bunch. Studies of Coherent Optical Transition
Radiation (COTR) allow us to see whether or not such bunchingis present. We present pilot results of COTR experiments carriedout at the SwissFEL Injector Test Facility. Optical transition
radiation is generated at an aluminium-coated silicon wafer thatcan be inserted into the beam. This can either be imaged to a
CCD camera, or focused into a spectrometer with a spectral
range from 200 nm to 925 nm. The compression of the electron
bunches was varied, and data was recorded at different bunch

lengths. Spectral data shows a clear gain of the signal and a shift
towards the infrared for a stronger compression of the bunches.
Results indicate that the spectrum fluctuates at maximum
compression. This is consistent with fluctuations observed in
COTR images.
MOPA45 Study of Beam Length Measurement based on TM010 Mode -Renxian Yuan, Yongbin Leng, Luyang Yu, Weimin Zhou (SINAP,
Shanghai)Beam length measurement in frequency domain is a familiar
method, and the resolution is seriously limited by the systemsignal-noise-ratio (SNR) and the beam length measured. Usually
this method can only obtain the resolution about ~10ps withbeam length ~30ps when using signal from button or stripline
BPM. But in FEL case, the beam length is the ps or sub-ps order.
The paper discusses the probability of beam length
measurement based on the TM010 mode in FEL case. When
adopting High Order Mode(HOM) reject and system gain
control, the system SNR can arrive at 110dB and the resolution
can achieve 30fs with beam length ps or sub-ps.

Darmstadt, Darmstadt), Alexander Kuhl (Uni HH, Hamburg)

At the Free Electron Laser FLASH at DESY, the installed Bunch
Arrival-time Monitors (BAMs) use an electro-optical detection
scheme for arrival-time measurements. The achieved time
resolution is in the sub-10 fs range for bunch charges higher
than 500 pC. The extension of FLASH II and the European X-ray
Free Electron Laser Project (XFEL) foresees a low charge
operation mode with bunch charge of 20 pC or less. The time
resolution of the BAMs significantly drops as the bunch charge
reduces (*). By expanding the bandwidth of the pickups one canincrease the time resolution at low charges. In this paper, we
present the characterization results of the manufactured
cone-shaped pickups introduced in (**) with a bandwidth up to
40 GHz. The pickups mounted in a vacuum body exhibit
four-fold rotational symmetry with respect to the beam pipe.
Due to different beam pipe apertures for FLASH and XFEL, twobodies are manufactured. The rf properties of the mounted

Mavric, Holger Schlarb, Cezary Sydlo (DESY, Hamburg)

In order to obtain ultra-short bunches in the Free Electron Laser
FLASH at DESY, the electron beam is compressed in magnetic
chicanes. Precise knowledge of the beam position in the
chicane is of great significance for the longitudinal dynamics
control.
Inthecurrent

cylindrical
pickup-striplines mounted perpendicularly to the beam areused as a Beam Position Monitor (BPM)(*). One can determine
the horizontal beam position by measuring the phase differenceof the beam induced signal at opposite ends of a pickup. Due tothe different electrical and mechanical requirements for theEuropean XFEL a new BPM has to be developed. In this paper,
we present the design and analysis of a planar transmission line
structure which is planned to be used as a BPM in the European
XFEL. The planar design of the pickups can provide for proper
impedance match to the subsequent electronics as well as
sufficient mechanical stability along the aperture when usingalumina substrates. A scaled non-hermetic prototype of the
BPM is built and characterized by scattering parameters. The
measurement results are compared to simulations obtained by

MOPA48 Measurement of Temporal Resolution and Detection Efficiency of
X-ray Streak Camera by Single Photon Images - Akira Mochihashi,

Mitsuhiro Masaki, Haruo Ohkuma, Shiro Takano, Kazuhiro
Tamura (JASRI/SPring-8, Hyogo-ken)

In the third generation and the next generation synchrotron
radiation light sources, the electron beam bunch length of ps ~sub-ps is expected to be achieved. An X-ray streak camera(X-SC) can directly measure the temporal width of X-ray
synchrotron radiation pulse. The temporal resolution of X-SC
depends on the initial velocity distribution of thephotoelectrons from a photocathode which converts the X-ray
photons to the photoelectrons. To measure the temporal
resolution of the X-SC, we have observed 'single photon' streak
camera images and measured the temporal spread of theimages. By this 'single photon' experiment, we have evaluated42

the dependence of the temporal resolution and the detection
efficiency on the photon energy. We have also tried to evaluate
the dependence of the temporal resolution and the detection
efficiency on the thickness of the photocathode. For thispurpose, we have developed a multi-array type CsIphotocathode with 3 different thickness of the photocathode.
The experimental setups, and the results of the measurementsof the temporal spread and the detection efficiency of the single
photon events will be presented.

FELs have greatly interested for the short-wavelength region.
However, their temporal profile and frequency spectra haveshot-to-shot fluctuation by a SASE process. One of thepromising approached for the problems is a seeded FEL schemeby using a full-coherent light source. The seeded FEL has been
demonstrated in the EUV region by employ the high-orderharmonics (HH) generation from an external laser source at the
SCSS test-accelerator in the SPring-8. It is important for the
HH-seeded FEL scheme to synchronize and overlap between
the seeding laser pulse and the electron bunch. Their timing
difference and laser spatial pointing is drifting. Therefore, atiming feedback and non-destructive monitor are necessary tooperate seeded FEL continuously. We have constructed thetiming monitor based on Electro-Optic (EO) sampling which ismeasure the timing difference the seeded laser pulse and theelectron bunch simultaneously with the seeded FEL process.
The probe laser pulse for the EO-sampling system is opticallysplit from the common external HH laser driver for the seeded
FEL. The EO-sampling system is able to use timing feedback forcontinual operation of the HH-seededFEL.

the IP1 (ATLAS) and IP5 (CMS) regions of the LHC. Thischamber is designed to measure the relative bunch-by-bunch
collision rate of the LHC from 1028 cm-2s-1 during beamcommissioning all the way up to the expected full luminosity of1034 cm-2s-1 at 7.0 TeV. These high-pressure ionizationchambers measure the intensity of hadronic/electromagnetic
showers produced by the forward neutral particles of LHC
collisions. They are designed to withstand the high radiation
produced by these forward collisions and are currently used in
LHC operations. This paper covers the detector's design andperformance in measuring both pp and PbPb collisions during
LHC operation, including a comparison with the ATLAS and

modeling of the detectors and the ability to predict how thedetector will respond to the higher energy and intensity

At National Institute of Radiological Sciences, more than 6500
patients have been successfully treated by carbon beams since
1994. The successful results of treatments have led us toconstruct a new treatment facility equipped withthree-dimensional pencil beam scanning irradiation system. The
commissioning of NIRS fast scanning system installed into the
new facility was started in September 2010, and the treatment
with scanned ion beam was started in May 2011. In thescanning delivery system, beam monitors are some of the mostimportant components. In order to measure and control thedose of each spot, the main and the sub ionization chambers
are placed separately as flux monitors. For monitoring of thescanned beam position, a beam position monitor, which ismulti-wire proportional chamber, is installed just downstream
from the flux monitors. This monitor can output not only thebeam position but also the 2D fluence distribution using
dynamic fast convolution algorithm. In this paper, the design
and the commissioning of these monitors are described.

At SPring-8 synchrotron radiation (SR) in both the X-ray and thevisible bands is exploited in the two diagnostics beamlines. The
diagnostics I beamline has a dipole magnet source. The beam
size is measured by imaging with the zoneplate X-ray optics.
Recently, the transfer line of the visible light has been upgraded.
The in-vacuum mirror was replaced to increase the acceptanceof the visible photons. A new dark room was built and dedicatedto the gated photon counting system for bunch purity
monitoring. To improve the performance, the input optics of thevisible streak camera was replaced by a reflective optics. Studyof the power fluctuation of visible SR pulse is in progress todevelop a diagnostic method of short bunch length. The
diagnostics II has an insertion device (ID). To monitor stabilitiesof the ID photon beam, a position monitor for the white X-ray
beam based on a CVD diamond screen was installed. A
turn-by-turn diagnostics system using the monochromatic X-ray
beam was developed to observe fast phenomena such as beam
oscillation at injection for top-up and beam blowups caused byinstabilities. Study of temporal resolution of the X-ray streak
camera is also in progress.

MOPB55 Electron Cloud Measurements using Shielded Pickups at CesrTA- John Sikora, James Arthur Crittenden, David Rubin (CLASSE,

was reconfigured as the Cornell Electron Storage Ring Test
Accelerator (CesrTA). An important part of the research at
CesrTA is the study of the growth, decay and mitigation ofelectron clouds. Electron Cloud (EC) densities can be measured
with a Shielded Pickup (SPU), where cloud electrons pass into
the detector through an array of small holes in the wall of thebeam-pipe. The signals produced by SPU have proved to bevery useful in measuring the mitigating effect of different
vacuum chamber surfaces - including differences in quantum
efficiency as well as secondary and elastic yield. This has beenaccomplished through the careful comparison of observed
signals with the output of the EC simulation code ECLOUD. We
present example comparisons of data and simulation that show
the effect of different surfaces as well as beam conditioning
effects. In addition, some data has been acquired using asolenoid to produce a longitudinal magnetic field at the SPU.
We will present our current understanding of the effect of alongitudinal magnetic field on SPU signals.

radiation (DR) beams from two shifted plates (double DR target)
may be used instead an interferometer [2]. Recently thecoherent DR interferometry scheme at the SINAP accelerator
facility was established [3]. Here we report the results ofcomparing the first measurement from such a technique withthe measurement from Michelson interferometer. The
parameters of fs linac are described in [4]. The DR target wasconsisted of two plates made from aluminum foil. The
pyroelectric detector SPI-D-62 was used. The analysis of resultsfrom two techniques gives the same estimated bunch length
about 660 fs (0.2 mm), which confirms the ability of the
proposedtechniquefor
non-invasivebunchlengthmeasurements in the sub-picosecond range without acomplicated scheme like Michelson interferometer or similar.

An extremely wide aperture relay optical system based onOffner system has been designed and constracted for OTR

MOPB68 Development of Profile Monitor System for High Intense
Spallation Neutron Source - Shin-ichiro Meigo (JAEA/J-PARC,

Tokai-Mura, Naka-Gun, Ibaraki-Ken)

At the JSNS in J-PARC, a mercury target is employed as theneutron production target. It is well known that the damage on
the mercury target is promotional to the 4th power of the peakcurrent density of the primary proton beam on the target. For
the high intense neutron source, the profile on the target isimportant to drive the neutron source with the continuously
observation of the profile. We have developed to Multi Wire
Profile Monitor System (MWPM). During beam operation, when
the abnormally of the beam is found, the beam is cut out by the
Machine Protection System (MPS). For the measurement of thetwo dimension observation on the target, we have developed
the system based on the residual radiation measurement byusing an imaging plate (IP), It is found that the both result by the
MWPM and IP shows good agreement.

Hirotaka Shimizu (KEK, Ibaraki), Arpit Ashok Rawankar(Sokendai, Ibaraki), Nobuhiro Terunuma, Junji Urakawa(Sokendai, Ibaraki; KEK, Ibaraki), Yan You (TUB, Beijing)

Production and handling of a low emittance beam is one of the
key technologies for linear colliders. The Accelerator Test
Facility (ATF) was constructed at KEK to study low emittancebeam physics and to develop the technologies associated with
it. In ATF damping ring, the vertical beam size is less than 10
μm. To measure it precisely, a thin and intense laser beam isrequired. We utilize a pulsed four mirror optical cavity based on
IR laser oscillator to fulfill this requirement. With pulsed green
laser oscillator, the beam waist will reduce by factor of 2.
Therefore, with green laser oscillator, effective electron-photon
collision can be observed. Minimum beam waist is obtained insagittal plane. Special type of mirror alignment scheme is used
to make a compact four mirror optical cavity. With Pulsed laser
oscillator the electron beam scanning is very fast as compare to
CW Laser wire system. Profile of electron beam can be

MOPB70 The Synchrotron Radiation Diagnostic Beam line of SSRF - Jie

Chen, Zhichu Chen, Guoqing Huang, Yongbin Leng, Kairong Ye(SINAP, Shanghai)

The synchrotron radiation photon beam line has been operated
since 2009 at Shanghai Synchrotron Radiation Facility. There
are two diagnostic beam lines of the storage ring behindbending magnet, which is employed conventional X-ray andvisible imaging techniques. A synchrotron radiation (SR)interferometer using visible light region in order to measure thesmall transverse electron beam size (about 22μm); lowemittance and a low coupling. A small off-axis mirror is set forthe convenience of the observation. Wave front testing is used
for interferometer to calibrate the deformation effect of opticalcomponents. An X-ray pin-hole camera is also employed in the
diagnostics beamline of the ring to characterize beam. Typicallythe point spread function of the X-ray pinhole camera iscalculated via analytical or numerical method. Those two
methods check each other. As a result, the measurement with
SR system has quite enough resolution of itself even though theabsolute beam size acquired. The existed system suffers withdynamic problem for beam physics studies. It has beenmeasured 2.8nm.rad in small emittance mode at SSRF.
MOPB72 First Measurements with Coded Aperture X-ray Monitor at the
ATF2 Extraction Line - John Walter Flanagan, Hitoshi Fukuma,

Hitomi Ikeda, Toshiyuki Mitsuhashi (KEK, Ibaraki)

The ATF2 extraction line is used as a test-bed for technologies
needed for the ILC final-focus region. An x-ray extraction beamline has been constructed at the final upstream bend before theextraction line straight section, for development and testing of
optics and readout systems for a coded aperture-based imaging
system. The x-ray monitor is expected to eventually be able tomeasure single-shot vertical bunch sizes down to a few microns
in size at its source location in the ATF2 extraction line.
Preliminary scanned measurements have been made withbeams in the ~15 micron range, and it is planned to make moremeasurements with further-tuned beam, and with fast read-out
electronics. The details of the layout, expected performance,and preliminary measurement results will be presented.

A high brightness photoelectron injector must be developed asa part of the BERLinPro program. The injector is designed to
produce an electron beam with 100 mA average current and anormalized emittance of 1 mm*mrad. The project will be
realized in two stages. First with a Pb cathode in a SRF gun,work ongoing, followed by a normal conducting CsK2Sb
cathode capable of generating high current beams. In the firststage we have measured the fundamental beam parameters
bunch charge, beam energy and energy spread with a special
focus on the measurement of the transverse beam profiles. We
also discuss our plans for the beam characterization at highcurrents.

In the TIARA AVF cyclotron facility of JAEA, we are developing anirradiation technique of a large-area uniform ion beam formed
by nonlinear focusing using multipole magnets. It is
indispensable to perform beam tuning and evaluation of thebeam quality at the same time for efficient operation. Therefore,
we developed a real-time beam profile measurement systemcomposed of two CCD cameras, fluorescent screens, and an
image analysis program based on LabVIEW. In order to measure
the transverse intensity distribution of the beam through theluminance map converted from a camera image, the5351

characteristics of fluorescent screens, DRZ (Gd2O2S:Tb) andAF995R (Al2O3:Cr), were investigated using several species ofion beams. It was found that the light yield from the DRZ-HIGH
screen irradiated with 10 MeV H+ beam was increased linearlywith the particle fluence rate from 5×10^7 to 5×10^8 [cm-2･s-1] and that the relative transverse intensity distribution could
be obtained from the fluorescence in real time. It was also
confirmed that the intensity distribution measured in thissystem agreed well with the relative intensity distribution
obtained with a Gafchromic radiochromic film.
MOPB76 Evaluation of a Fluorescent Screen with a CCD System for Quality
Assurance in Heavy-Ion Beam Scanning Irradiation System -Yousuke Hara, Takuji Furukawa [on leave], Taku Inaniwa [onleave], Kota Mizushima [on leave], Koji Noda [on leave], ShinjiSato [on leave], Toshiyuki Shirai [on leave], Eri Takeshita [onleave] (NIRS, Chiba-shi)

The precise heavy-ion therapy such as the scanning irradiation
system necessitates the precise quality assurance (QA)
procedures to verify the performance of therapeutic scanned
ion beams. To evaluate the uniformity of the 2D field,
radiographic film is used due to its high spatial resolution andsuit for the measurements of the integral dose. However, thistechnique is time consuming. Thus, we developed the QA toolwith high spatial resolution to verify accuracy of the lateral size,
position and uniformity of scanned ion beams in clinicalapplication at the HIMAC, which we called the QA-SCN. The
QA-SCN consists of a fluorescent screen, a CCD camera, amirror, camera controllers and a dark box to protect against
surrounding light. In this paper, to evaluate the performance of
the QA-SCN, we compared the results obtained by using it withthe measurements by radiographic film performed in the same
experimental conditions. Also, we verified several types ofcorrections about errors, e.g. background, vignetting, to distort
the measurement results. As a result, we confirmed that the
QA-SCN can be used as the system for QA procedures oftherapeutic scanned ion beams.

making it a robust and inexpensive instrument. The SPM issuitable for high intensity operation rather than operation with
low intensity polarised beams. A multichannel PMT is used todetect scintillation light. The rate of detectable scintillation
events is about three orders of magnitude lower compared to
the rate of ionisation events. To boost the photon yield, small
amounts of nitrogen are injected into the SPM vacuum chamber.
An adjustable light focusing system is being built to optimise the
SPM performance for different machine operation modes. The
new system allows using a variety of optical components
ranging from single lenses to high-grade camera objectives.
Cylindrical lenses are considered to further boost the sensitivity
by better fitting the beam image to the detector geometry. The
latest experimental results and the new design of the opticalsystem are presented.

A two-dimensional beam imaging system with a terbium-doped
gadolinium oxysulfide (Gd2O2S:Tb) phosphor screen andhigh-speed charge coupled device (CCD) camera has beenused to measure the beam spot for scanned carbon-ion therapy
at National Institute of Radiological Sciences (NIRS). The systemenables us to obtain one image of the beam spot every 20
milliseconds. The fluctuation of the unscanned-beam spot sizeand position was observed in the isocenter to verify the timestability of the delivered beam for scanning irradiation. The
beam imaging system also functions as a beam alignment
adjustment system by setting a steel sphere at the isocenter. For
quality assurance, the beam alignment is routinely checked byobserving a shadow of the steel sphere on the beam spot image,and it is confirmed that the misalignment of the beam is smaller
than the tolerance of 0.5 mm.

MOPB80 High Dynamic Range Beam Imaging with Two Simultaneously
Sampling CCDs - Pavel Evtushenko (JLAB, Newport News,

Virginia)

Transverse beam profile measurement with sufficiently highdynamic range (HDR) is a key diagnostic to measure the beamhalo, understand its sources and evolution. In this contribution
we describe our initial experience with the HDR imaging of theelectron beam at the JLab FEL. On contrary to HDR
measurements made with wire scanners in counting mode,
which provide only two or three 1D projections of transverse
beam distribution, imaging allows to measure the distribution
itself. That is especially important for non-equilibrium beams in
the LINACs. The measurements were made by means ofsimultaneous imaging with two CCD sensors with different
exposure time. Two images are combined then numerically in to
one HDR image. The system works as an online tool providing
HDR images at 4 Hz. An optically polished YAG:Ce crystal withthe thickness of 100 um was used for the measurements. Whentested with a laser beam images with the DR of about 1E+5
were obtained. With the electron beam the DR was somewhat
smaller due to the limitations in the time structure of thetune-up beam macro pulse.

electrons are guided to the segmented electrode with a uniform
electrostatic field applied in the gap. A uniform magnetic field isapplied parallel to the electric field to reduce diffusion ofelectrons travelling to the electrodes. Typical spatial resolutionof the RGIPMs with a 10 cm gap, a 10 V/cm electrostatic field,
and a 400 gauss magnetic field at center is 0.5 mm. The
collected charge is integrated during every extraction period(typically 2 second in 6 second accelerator cycle). Subtracting
background distributions measured during off-beam period,
profile distributions are measured clearly. The 14 RGIPMs
installed in the slow-extraction beam line are working stably forthe 30 GeV-0.46 uA proton beam at current maximum. In thiscontribution, detailed specifications and performance of thepresent RGIPMs will be reported.
MOPB82 Bunch-Compressor Transverse Profile Monitors of the SwissFEL
Injector Test Facility - Gian Luca Orlandi, Rasmus Ischebeck,

The 250 MeV SwissFEL Injector Test Facility (SITF) is the test
bed of the future 5.7 GeV SwissFEL linac that will drive a
coherent FEL light source in the wavelength range 7-0.7 and
0.7-0.1 nm. Aim of the SITF is to demonstrate the technicalfeasibility of producing and measuring 10 or 200pC electron
bunches with normalized emittance down to 0.25 µm. A further
goal is to demonstrate that the electron beam quality ispreserved in the acceleration process, in the X-Band linearizer
and the magnetic compression from about 10 ps down to 200 fs.
The SITF movable magnetic bunch-compressor is equippedwith several CCD/CMOS cameras for monitoring the beamtransverse profile and determining the beam energy spread: a
Ce:YAG screen and an OTR screen camera at the mid-point of
the bunch compressor and a SR camera imaging in the visible

instrumentations, in particular in the low charge limit, andmeasurements of the beam energy spread vs. the compression
factor will be presented.

A fast gated intensified CCD camera was used to observe the57

2012/Oct/01

beam profile turn-by-turn in the visible light region. Using thevisible light from the optical diagnostic beamline on the storage
ring at the Australian Synchrotron an optical telescope wasconstructed to focus an image on the ICCD. The event driven
timing system was then used to synchronise the camera with theinjected beam. To overcome the problem of dynamic range
between the amount of charge in an injected bunch and thestored beam, the beam was dumped by slowly phase flipping
the RF by 180 degrees between each one 1 Hz injection cycle.
The injection process was verified to be stable enough so thatmeasurements of the different turns could be captured on
successive injections and did not need to be captured in single
shot. The beam was seen to come in relatively cleanly in a tightbeam but would then rapidly decohere due to the strong
non-linear fields needed to run the storage ring at highchromaticity. It would take thousands of turns for the beam todamp down again and recohere into a tight beam spot again.
This measurement technique will be used to tune the storage
ring injection process.

At the 1.5GeV electron storage ring NewSUBARU, the twodifferent kinds of systems for measuring betatron tunes havebeen developed: the high precision tune monitor and that for
automatic correction. The vertical and horizontal tunes can beobserved during the user time, because a stripe-line kicker toenlarge the beam lifetime vertically shakes electron beams. The
high-precision tune monitor has the resolution of 0.0002 anduses frequency analysis methods such as SRSA, zoom FFT, STFT,
in addition to usual FFT. Tune shifts due to a slight difference offilling patterns during top-up operations can be observed with
thismonitor.

current, the difference of filling patterns during top-up
operations, and the energy ramp from 1.0 to 1.5 GeV. Thissystem estimates betatron tunes every 0.5 sec and can keep
tunes to the optimal values. The system also has a tune survey

MOPB87 Development and First Tests of a High Sensitivity Charge Monitor
for SwissFEL - Sebastien Artinian, Julien Bergoz, Frank Stulle(BERGOZ Instrumentation, Saint Genis Pouilly), Patrick Pollet,
Volker Schlott (PSI, Villigen)

The compact X-ray free electron laser SwissFEL, which ispresently under development at the Paul Scherrer Institut (PSI)
in Villigen, Switzerland, will operate at comparably low charges,
allowing the compression of the electron bunches to a few
femto-seconds (nominal 200 pC mode) and even towards theatto-second range (short bunch 10 pC mode). A high precision
charge measurement turns out to be a challenge, especially inthe presence of dark currents, which may occur from highgradient RF gun and accelerating structure operation. In
response to this challenge, a higher sensitivity chargetransformer and new beam charge monitor electronics weredeveloped in collaboration between Bergoz Instrumentation
and PSI. The Turbo-ICT captures sub-pC bunch charge thanks
to a new magnetic alloy exhibiting very low core loss.
Transmission over a carrier using narrow-band cable television
technique preserves the signal integrity from the Turbo-ICT to
the BCM-RF. Electro-magnetic and RF interferences are strongly
attenuated; the dark current signal is suppressed. First beam
test results, which have been performed at the SwissFEL Test
Injector Facility (STIF), are presented in this contribution.

TUTA02 BPM Electrode and High Power Feedthrough - Special Topics in
Wideband Feedthrough - Makoto Tobiyama (KEK, Ibaraki)
Since most of the beam in accelerator runs in the vacuum

get or to put the RF signal from or to beam. For example, we canget the beam signal by using button-type electrode which haveelectrical isolation material to seal the vacuum. Now, many
types of vacuum feedthrough with coaxial structure areavailable commercially. Nevertheless, it is meaningful tounderstand the design principle of the feedthough needed forthe beam instrumentation, especially for short bunch length,

the feedthrough such as BPM electrodes or high power

The generation of ultrashort x-ray pulses in the femtosecond (fs)regime in FELs requires electron bunches with lengths

The SPring-8 linac has been operated as an injector to theelectron storage ring, NewSUBARU. Because of the small
acceptance of the ring, fine parameter tuning is required for the
stable top-up injection. In that process, some single shot linac
beam measurements were necessary to understand theshot-by-shot fluctuation of the injection efficiency. We used theelectron ring itself as a linac beam monitor. The time-resolving
visible light monitor in the ring records the profiles of theinjected linac beam for many revolutions. The pulse width forthe single rf bucket (500MHz) of the ring is normally 1 ns, whichcontains 3 linac bunches (2856MHz). The time profile in thering gives the energy profile at after 1/4 of the synchrotron

oscillation period. The spatial profile of several revolutions,recorded by a double-sweep streak camera or ICCD gatedcamera, gives a beam emittance of a single-shot. The streak
camera enables the bunch by bunch measurement. The
effective resolution depends on the beta function of the ring,which can easily be changed. For the vertical emittance, ourspatial resolution of 0.3 mm FWHM at βy = 17 m was goodenough to identify the quadrupole mismatch.
TUIC02 Direct Observation of the Dust-trapping Phenomenon - Yasunori

Tanimoto (KEK, Ibaraki)

Dust trapping has long been an unwelcome and mysterious
phenomenon in electron storage rings. As it leads to a sudden
decrease in beam lifetime, dust trapping has been a perpetualnuisance at the Photon Factory Advanced Ring (PF-AR) since its
beginning in the 1980s. However, during recent research on
dust trapping at the PF-AR, video cameras serendipitously
captured the culprit behind this phenomenon; the cameras
recorded a luminous micro-particle trapped in the electron
beam, just as if a shooting star were traveling in the beam tube.
In the successive research, supersensitive cameras repeatedly
observed trapped dust particles, and revealed that they
behaved differently under different conditions. My presentation
will summarize these experimental results, as well as long-term
statistics supporting present dust-trapping theories.

the context of the TIARA WP6, has already achieved the world's

However, the resolution limit of the present SLS emittancemonitor has also been reached thus, to further continue theemittance minimization program the construction of an

to be verified through realizing its design vertical e- beam size(σy ) of 37 nm. The 'IPBSM', installed at ATF2's virtual IP, is the
only existing beam size monitor capable of measuring σy < 100
nm, making it indispensable for ATF's goals and R&D at future
LCs. This owes to a novel technique of colliding e- beam against
laser interference fringes. σy is derived from the modulation
depth of resulting Compton photons, which is large for small σy.
The measurable range from O(10) nm ~ a few μm, is controlled
by switching between laser crossing angles θ = 174° , 30°, and
2° - 8° . In early 2011, measuring σy < 300 nm was hindered by
an immense earthquake and heavy signal jitters. The ensuing
recovery and upgrades stabilized the laser system and improved
resolution to 5%. In spring 2012, we commissioned advanced
crossing angle modes by consistently measuring σy ≥ 150 nm.
Our goals for the autumn 2012 run is to stably measure σy <50 nm. Major hardware upgrades during the summer aim at
more reliable alignment and optimization of specialized
functions to suppress bias factors.

TUPA06 Pulsed Electron Beam Current and Flux Monitor for theRace-Track Microtron - Sanjay Daga Dhole, Shahzad Akhter,

Vasnat Nagesh Bhoraskar, Bhushankumar Jagnnath Patil, Ninad
S. Shinde (University of Pune, Pune)

In electron irradiation experiments on the materials, a true
current of the electron beam is to be known to calculate theelectron fluence received by the sample. Therefore, a pulsed
electron beam current and flux monitor alongwith electronicsystem for an electron accelerator called Race-Track Microtron
has been designed and developed. The sensing device used
was a ferrite core having suitable number of turns of copper
wire wound around it, through which the electron beam waspassed without loss in the intensity. With an appropriate
developed electronic circuit, the instantaneous value of theinduced voltage was measured which in turn provides value ofthe electron beam pulsed current. The total charge passed
through the ferrite core per unit time was therefore recorded
and an integrated value of the total charge in a given period
could be derived. This system can be used to measure theelectron flux in the range from 10^8 electron/cm^2 to 10^16electron/cm^2. Moreover, this system has been usedsuccessfully in a few electron irradiation experiments where theknowledge of the electron fluence received by the sample isrequired.

harmless. Meanwhile, the DCCTs in the storage ring of Shanghai
Synchrotron Radiation Facility (SSRF) have been suffering fromvarious noise and the signals from the BPMs could be an aid toprovide the beam current more accurately. There're 140 BPMs
in the storage ring in SSRF but not all of them are suitable forthis particular usage. This article focuses on the methods usedhere to dynamicly choose the BPMs that meet the criteria.
TUPA08 Application of Single Crystal Diamonds (sCVD) as Beam
Conditions Monitors at LHC - Maria Elena Castro Carballo (DESY

Zeuthen, Zeuthen)The properties of the single-crystal diamond (scCVD): radiation
hardness, low leakage current and fast signal, make it suitablefor use as a particle detector in areas of high radiation dose. The
Beam Conditions and Radiation Monitoring system (BRM) of the
CMS experiment has a monitor (BCM1F) consisting of 4
modules located 1.8 m away from the interaction point, on bothsides. Each module contains a sensor, radiation hard FEE andoptical transmission of the signal. It counts single particles ofbeam halo, beam-gas, machine induced background, andcollision products. The BRM protects CMS from high beamlosses and provides feedback to the LHC and CMS on the beam
conditions. The BCM1F sub-detector is very helpful as it is able
to provide different background information together withluminosity correlations. Additional scCVD sensors are being
installed in the LHC ring to be used as BLMs. The new BLM
system (BCM1F4LHC) will be composed of 8 diamonds in points
likely to suffer from beam losses. Nowadays, four sensors deliver
information of hit rates that are correlated to the existing BLMs.
A characterization of both BCM1F systems is presented.

TUPA10 Development of Optical Fiber Beam Loss Monitor System for the
KEK Photon Factory - Takashi Obina, Yoshiharu Yano (KEK,

Ibaraki)Beam loss monitor system using optical fibers has beendeveloped to determine the loss point of the injected beam at
the KEK Photon Factory (PF) electron storage ring. Large-core
optical fiber was installed along the vacuum chamber of thestorage ring, of which circumference is about 187m. In order tocover the whole location, total 10 optical fibers with the lengthof 30 m is used. Both ends of the fiber has been fed out of theradiation shield of the ring. The Cherenkov light produced by
the electron which is not captured in the ring, is detected by aphotomultiplier tube (PMT) attached on the upstream side of
the fiber. Rise-time of the PMT of 5 ns is fast enough todetermine the location of the beam loss point. In the KEK-PF,
two kinds of injection system, kicker magnets and a pulsed
sextupole magnet (PSM), has been used for the routine
operation. In this paper, details of the loss monitor system arereported and the difference of the two injection system will be
discussed.

TUPA13 Design Status of Beam Position Monitors for ADS Injector II
Proton LINAC - Yong Zhang, Xincai Kang, Min Li, Junxia Wu,

Jingzhe Zhang (IMP, Lanzhou)

Beam Position Monitors (BPM) based on capacitive pick-ups aredesigned for Accelerator-Driven System (ADS) Injector II proton
LINAC. This LINAC is aiming to produce a maximum design
current of 15 mA at the 10 MeV energy with an operating
frequency of 162.5 MHz. Non-interceptive BPM will be installed
to measure the transverse beam position and beam phase in thevacuum chamber. Depending on the location, the response of
the BPMs must be optimized for a beam with an energy range
from 2.1 up to 10 MeV and an average current between 0.01
and 15 mA. Apart from the broadening of the electromagnetic
field due to the low-beta beam, specific issues are affectingsome of the BPMs: tiny space in the transport line between the
RFQ and the cryomodule and the cryogenic temperature inside
the cryomodule. For this reason two types of BPMs are being
designed for each location (MEBT and cryomoudle). In thiscontribution, the present status of the design of each BPM will
be presented, focusing on the electromagnetic response forlow-beta beams.

TUPA16 HOM Choice Study with Test Electronics for use as Beam
Position Diagnostics in 3.9 GHz Accelerating Cavities in FLASH -Nicoleta Baboi, Bastian Lorbeer (DESY, Hamburg), Pei Zhang(DESY, Hamburg; UMAN, Manchester), Nathan Eddy, Brian
Fellenz, Manfred Wendt (Fermilab, Batavia)

Higher Order Modes (HOM) excited by the beam in the 3.9 GHz
accelerating cavities in FLASH can be used for beam position
diagnostics, as in a cavity beam position monitor. Previous
studies of the modal choices within the complicated spectrum
have revealed several options*: cavity modes with high coupling
to the beam, and therefore with the potential for better position
resolution, but which are propagating within all 4 cavities, andmodes localized in the cavities or the beam pipes, which cangive localized position information, but which provide worse
resolution. For a better characterization of these options, test
electronics has been built, which can down convert various
frequencies between about 4 and 9 GHz to 70 MHz. The
performance of various 20 MHz bands has been estimated. The
best resolution of 20 µm was found for some propagating modes.
Based on this study one band at ca. 5 GHz was chosen for highresolution position monitoring and a band at ca. 9 GHz for
localized monitoring.

TUPA18 Development of Beam Position Monitors for the SPIRAL2 Linac -Mohammed Ben Abdillah (IPN, Orsay)

The SPIRAL 2 facility will be able to deliver stable heavy ion
beams and deuteron beams at very high intensity, producing
and accelerating light and heavy rare ion beams. The driver will
accelerate between 0.15mA and 5 mA deuteron beam up to 20
MeV/u and also q/A=1/3 heavy ions up to 14.5 MeV/u. The
accurate tuning of the LINAC is essential for the operation of
SPIRAL2 and requires from the Beam Position Monitor (BPM)system the measurements of the beam transverse position, thephase of the beam with respect to the radiofrequency voltage
and the beam energy. Twenty three BPM were realized for
SPIRAL2. This paper addresses all aspects of the design,realization, and calibration of these BPM, while emphasizing thedetermination of the beam position and shape. The
measurements on the BPM are carried out on a test bench in
the laboratory: the position mapping with a resolution of 50 µm
is performed and the sensitivity to the beam displacement isabout 1.36dB/mm at the centre of the BPM. The
characterization of the beam shape is performed by means of a
special test bench configuration. An overview of the electronics
under realization for the BPM of the SPIRAL2 Linac is given.

we describe the design and construction of a first prototype
based on four scintillating fibers coupled to one photodiodeeach, to detect the light produced by the fibers whenintercepting the beam tails. The results of the first beam test
using a 6GeV proton beam from the PS accelerator at CERN are
also presented. This beam test, jointly with a previous
calibration test done with a radioactive source, has been served
to evaluate the different design options of the prototype and its
read-out electronic setup in order to define the best processing
method to get the beam position.

Accelerating Cavities - Thomas Wamsat (DESY, Hamburg)
Beam excited higher order modes (HOM) in 3.9GHz
accelerating cavities at the European XFEL are planned to be
used for beam position monitoring. The selected HOMs arelocated around 5440MHz and 9060MHz and are filtered in a
bandwidth of 100MHz. A downconverter test electronics
converts the HOMs to an intermediate frequency of 70MHz. TheµTCA (Micro Telecommunications Computing Architecture)
standard will be used for the XFEL. Thus it is important to have a

TUPA25 Signal Transmission Characteristics in Stripline-Type Beam
Position Monitor - Tsuyoshi Suwada (KEK, Ibaraki)
New stripline-type beam position monitor (BPM) system isunder development at the KEKB injector linac in order tomeasure transverse beam positions with a high precision lessthan 10 micron meters towards the Super KEKB-factory (SKEKB)
at KEK. During the KEKB operation, conventional stripline-type
BPMs with a position resolution of 0.1 mm have been working
well. However, the high-precision BPM system is strongly
required for the SKEKB operation to stably accelerate
single-bunch electron and positron beams with high bunchcharges of ~5 nC/bunch, and also to keep the beam stability
with higher brightness. The new stripline-type BPMs with large
aperture compared with previously designed BPMs, which will
be installed just after the positron production and capture
section, have been designed. In this report, the basic design for
fabricating the prototype stripline-type BPM, and, especially,
theoretical analysis and experimental investigations on thesignal propagation characteristics and performance along thestripling electrodes are described in detail on the base of acoupled-mode analysis of uniform coupled transmission lines.

TUPA28 Ultra-fast Data Acquisition System for Coherent Synchrotron THz
Radiation based on YBCO Film Detectors - Michele Caselle (KIT,

Eggenstein-Leopoldshafen), Suren A. Chilingarian (FZ Karlsruhe,
Karlsruhe)

The ANKA synchrotron radiation source located at the Karlsruhe
Institute of Technology in Germany operates in the energy range
between 0.5-2.5GeV and provides coherent synchrotron
radiation. To resolve the ultra-short terahertz pulses emitted bya single bunch, thin YBCO superconducting film detectors havebeen developed. A response time of 45ps was determined as
the FWHM of the voltage transient at the output of the analog
amplifier. A novel and high accuracy data acquisitionarchitecture for sampling of the individual ultra-short terahertz
pulses for coherent synchrotron radiation is presented.The highbandwidth acquisition chain consists of wide bandwidth low
noise amplifier connected to a high-speed digitizer board. The
digitizer board is a made-in-house board designed for samplingof the fast pulse signals with pulse width between few tens ofpicosecond until 100ps.A prototype setup with terahertz
detectors,digitizer boards and the highthroughput FPGA
framework has been successfully developed and tested at ANKA.
The overview of the experimental setup including the YBCO
detector technology and the preliminary results with single andmultibunch filling pattern will be discussed.

standardize the implementation, where the acquisition modules
share a common build and are connected through astandardized interface to a survey reader. The reader collects
regularly data and controls the readout intervals. The

The aim of the BLM Dual Polarity card under development at theEuropean Organisation for Nuclear Research (CERN) is tomeasure and digitise with high precision the current produced
by several types of beam loss detectors. In its default
configuration, it is expected to provide data to the processing
electronics through two point-to-point connections withbidirectional multi-gigabit optical links. For the development

Van Winkle (SLAC, Menlo Park, California), Raffaello Secondo(CERN, Geneva)

The 4GS/sec electron cloud and transverse mode coupledinstability (TMCI) control system in development for the CERN
Super Proton Synchrotron (SPS) requires 1.5GHz of processing
bandwidth for the beam pickups and signal digitizer. An
exponentially tapered stripline pickup has sufficient bandwidth,
but has a phase response that distorts the beam signal in thetime domain. We report on results from the design andimplementation of an equalizer for the front end signal
processing with correction for the pickup and cable responses.
Using a model of the transfer functions for the pickups and thecabling, we determine a desired frequency response for theequalizer. Design for the circuitry, component value fitting is
discussed as well as board construction and reduction ofparasitic impedances. Finally, we show results from themeasurement of an assembled equalizer, compare them withsimulations and show beam signals from use at the SPS.

TUPA34 Inverse Response Matrix Computation for the Storage Ring Slow
Orbit Feedback Control: Synthesized Topological Inversion
Computation - Jay Min Lee, Jung Yun Huang, Changbum Kim(PAL, Pohang, Kyungbuk)Using the derivative response matrix between BPM-data and
MPS-setting, we described the inverse computation
methodology for the storage ring orbit feedback control.
Practically useful for SOFB with assistance of FOFB, the inverseof SVD manipulation is less efficient because a type ofconsecutive instability noise irreversibly accumulates in the
beam trajectory deviation. In contrast, a novel numerical recipe
based on topological math can lead to a self-consistent solution,
dramatically suppressing ill-posed instability problems. Thisapproach, known as a singularity regularization method, makes
it feasible to compute a system-matched de-noising filter. The
response matrix in H/V dimensions reflects a global beam
dynamics along the storage ring lattices. Matrix refinement
manipulatcan can be made to filter out the uncertainty ofmeasurement errors escaping from beam dynamics constraints.
Then we believe that algorithm filter can be effective as asoftware part of FOFB control. Our math STIC (Synthesized
Topological Inversion Computation*) appears to be the mostreliable inverse computation methodology. Our PLS-2 response
matrix will be presented to explain our ORBIT-STIC test.

TUPA36 A 4 GSa/s Bunch Slice Feedback Processor Demonstrator for the
SPS - John Dusatko, John Fox, Claudio Hector Rivetta, Ozhan

Turgut (SLAC, Menlo Park, California)

Intra-bunch instabilities driven by the presence of electron
cloud and transverse mode coupled instabilities (TMCI) at the
CERN Super Proton Synchrotron (SPS) have been observed with
LHC beam, and are an area of concern. To date, efforts tounderstand and mitigate this effect have included numericalsimulations of the instabilities and models of possible feedback
control methods. An experimental program in 2011 used a 4
GSa/s excitation system to successfully drive head-tail modes
within a single SPS proton bunch. The next step to control
intra-bunch instabilities is the development of a 4 GSa/s DSP
system to investigate closed loop control on a small number ofbunches in the SPS. We present a system architecture andimplementation outline for this transverse feedback channel.
This processor uses a commercial FPGA board withcustom-designed ADC and DAC daughterboards for the
wideband input pickup/receiver and kicker signal output stages.
The system is reconfigurable to allow evaluation of possible
feedback control filter algorithms (FIR, IIR, etc.). This paper
describes the design of this system, with a focus on thedevelopment of the signal processing hardware.
TUPA37 FPGA Based Fast Orbit Feedback System for the Australian

An initial design for a Fast Global Orbit Feedback System basedon FPGAs has been proposed for the Australian SynchrotronLight Source (ASLS). The design uses a central processor (Xilinx

distribute the computed data to corrector magnet power
supplies. The network topology consists of two fibre optic rings.
The first ring is used by the Libera Electron's to aggregate thebeam position data at 10 kHz using Instrumentation

TUPA38 Current Status and Development Plan for RF Distribution andControl System of SPS Linac - Roengrut Rujanakraikarn (SLRI,

Nakhon Ratchasima)

The Siam Photon Source (SPS) is a dedicated synchrotron
radiation facility in Nakorn Ratchasima, Thailand. SPS routinely
serves various users with beam energy of 1.2 GeV. Its 40 MeV
linac has been operated for beam injection since the first light inDecember 2001. With an increasing user demand, the improved
stability and efficiency of the SPS linac is absolutely necessary.
In this report the RF distribution and phasing system of SPS
linac is described, which includes the system design andcurrent operation status. We also present a plan to upgrade thehardware of the waveguide power attenuator and phase shifter,
to develop the phase and amplitude detection unit for eachacceleration unit, and to implement the phase and amplitudecontrol system of the linac.

in the Single-shot Mode - Gerard Andonian (UCLA, Los Angeles,

California), Jayakar Charles Tobin Thangaraj (Fermilab, Batavia),
Alex Murokh, Marcos Ruelas (RadiaBeam, Santa Monica)

The determination of bunch length in the single-shot mode iscritical for many advanced accelerator and light source facilities
as ultra-short beams become more ubiquitous. These shortbeams (sub-ps) typically emit coherent radiation via transition
radiation (or synchrotron or edge radiation) in the terahertz(THz) frequency range. The Real-Time interferometer (RTI) is asolid-state, spatial interferometer that incorporates terahertz
optics and a novel linear, pyroelectric detector array thatgenerates single-shot interferograms that are directly correlated
to the beam bunch length. The device has been tested forcoherent sources in the IR, and recently demonstrated at the
Fermilab A0 test facility [1]. In this paper, we review the physicalconcepts, recent results, and potential future applications at
both the Brookhaven National Laboratory Accelerator Test
Facility and the SLAC National Laboratory FACET facility.

TUPA40 High Resolution Bunch Profile Determination with an X-band
Deflecting Cavity - Gerard Andonian (UCLA, Los Angeles,

California), Ronald Agustsson, Luigi Faillace, Alex Murokh,
Marcos Ruelas (RadiaBeam, Santa Monica)

The determination of the longitudinal profile of high-brightness
beams on the ~fs scale is important for many present-day
applications that employ ultra-short beams. A direct method tomeasure the beam profile in the temporal domain utilizes atransverse cavity operating in the zero-crossing mode. Here we
present the development and commissioning results of an
x-band deflecting cavity that is currently installed at the
Brookhaven National Laboratory Accelerator Test Facility. Initialstudies and simulations show that a temporal resolution of<10fs is achievable. In addition, we propose a method toenhance this resolution to the sub-fs scale with the addition of alaser-modulator (a high-power laser and an undulator) to
impose an angular modulation on the beam. This modulation, in
tandem with the transverse cavity, is resolvable on a distant
screen; simulations show that temporal resolutions on the
sub-fs scale are achievable.

Berkeley, California)

The technique of streaking an electron bunch with a RF
deflecting cavity to measure its bunch length is being applied ina new way at the Linac Coherent Light Source with the goal ofmeasuring the femtosecond temporal profile of the FEL photon
beam. A powerful X-band deflecting cavity is being installed
downstream of the FEL undulator and the streaked electron
beam will be observed at an energy spectrometer screen at thebeam dump. The single-shot measurements will reveal whichtime slices of the streaked beam have contributed to the FEL
process by virtue of their greater energy loss and energy spread
relative to the non-lasing portions of the electron bunch. Since
the diagnostic is located downstream of the undulator it can be
operated continuously without interrupting the beam to theusers. The resolution of the new X-band system will becompared to the existing S-band RF deflecting diagnostic
systems at SLAC and consideration is given to the required RFphase stability tolerances required for acceptable beam jitter on

resolution is achievable in the LCLS over a wide range of FEL
wavelengths and pulse lengths.
TUPA42 Beamline Optimisation and Image Processing for sub-ps Streak
Camera Bunch Length Measurement - Cyrille Thomas, Guenther

Rehm (Diamond, Oxfordshire), Ian Martin (JAI, Oxford)

Low alpha beam lattice at Diamond can generate bunch length
as small as 0.6ps. In order to be able to measure reliably such ashort bunch, we have been optimising the optical design of thevisible Diagnostics beamline, and we have implemented image
processing, taking into account the point spread function of thestreak camera. The beamline optical design has removed a large
chirp of 15ps/150nm bandwidth to 2ps /200nmbandwidth. It
has also permit the transport of almost all the available power,
increasing the power by a factor 20, yet maintaining thepossibility to focus the beam down to less than 20um into thestreak camera for the best static streak camera point spreadfunction. The deconvolution technique implemented extends
the performance of the streak camera to bunch length
measurement much smaller than the 1ps PSF of the streak
camera. In this paper we present these two essential features
required to measure sub-ps bunched with a streak camera.

The
FERMI
@ElettraseededFEL
hasdemandingsynchronization requirements and therefore an accurate
knowledge of longitudinal beam properties is of highimportance, both for the time profile and time jitter of theelectron beam at the entrance of the undulator chain. To fulfill
this requirement, an electro optical sampling (EOS) station
based on the spatial encoding scheme has been designed andinstalled in the FEL1 chain of FERMI. The paper describes thedesign criteria of this system, its specific features and the first
operational measurement results obtained. This diagnostics
allows for temporal coarse alignment of the seed laser with theelectron beam. This feature is described and results are
discussed. Finally, the paper provides also the guidelines for
future developments foreseen for this system.

TUPA44 Status of the LCLS Experiment Timing System - Josef Frisch,

Justin May, Stephen Smith (SLAC, Menlo Park, California)

X-ray / optical laser pump - probe experiments are used for asignificant fraction of the scientific work performed at LCLS. The
experimental laser systems are locked to the timing of theelectron beam through a combination of RF and optical fiber
based systems. The remaining ~100 femtosecond RMS jitter ofthe X-rays relative to the optical laser is measured shot-to-shotby both a RF timing detector, and by direct X-ray to opticalcross-correlation, and the result is used to correct theexperiment timing to 10s of femtoseconds. We present thepresent status of the system and plans for future upgrades.

Goodfellow, Jerry LaRue, Ziran Wu (SLAC, Menlo Park,
California), Dan Daranciang (Stanford University, Stanford,
California), Aaron Lindenberg (Stanford University, Stanford,
California; SLAC, Menlo Park, California)

At SLAC both LCLS and FACET produce highly compressed
electron bunches well suited to producing. At the LCLS x-ray
free-electron laser, 13-GeV bunches of up to 0.35 nC,
compressed to 20 fs RMS, generate intense broadband
terahertz radiation by coherent transition radiation when
passing through a 10-micron-thick beryllium foil 30 m
downstream of the undulator. FACET, a user facility foradvanced acceleration experiments, runs with 20-GeV, 3-nC
bunches compressed to 80 fs. THz is again generated by CTR
when the beam passes through a 1-micron titanium foil 10 m
upstream of the experimental table. We will report on thesesources and on spectral measurements used to find thelongitudinal profiles. We are beginning studies of electro-optic
and ferro-electric materials using THz and a fs Ti:sapphire laser,and of THz-driven catalysis. A 40-m-long transport line isplanned to bring THz from the FACET tunnel to a user hutch.
This may be followed by a 100-m line to transport THz to LCLS
users in the experimental hall.

Length Diagnostics at the LCLS - Timothy John Maxwell, Yuantao

Ding, Alan Stephen Fisher, Josef Frisch, Sasha Gilevich, Henrik
Loos (SLAC, Menlo Park, California), Christopher Behrens [onleave] (DESY, Hamburg)

Modern high-brightness accelerators such as laser plasma
wakefield and free-electron lasers continue the drive toever-shorter bunches. At low-charge (< 20 pC), bunches as
short as 10 fs are reported at the Linac Coherent Light Source(LCLS). Advanced time-resolved diagnostics approaching thefs-level have been proposed requiring the support of
rf-deflectors, modern laser systems, or other complex systems.
Though suffering from a loss of phase information, spectral
diagnostics remain appealing by comparison as compact,
low-cost systems suitable for deployment in beam dynamics
studies and operations instrumentation. Progress in mid-IR
imaging and detection of the corresponding micrometer-range
power spectrum has led to the continuing development of asingle-shot, 1.2 - 40 micrometer prism spectrometer for
ultra-short bunch length monitoring. In this paper we reportfurther analysis and experimental progress on the spectrometer
installation at LCLS.

The report deals with beam instrumentation of the electron
cooler for COSY storage ring. The electron cooler is anelectrostatic accelerator designed for beam energy up to 2 MeV
and electron current up to 3 A with recuperation. The electron
beam is immersed in longitudinal magnetic field so the electron
motion is strongly magnetized. The near-cathode electrode in
the electron gun is composed of four electrically isolated
sectors. Applying AC voltage to one sector allows tracing of
motion of that particular part of the beam. The electron beam

at CesrTA - John Sikora, Michael Gerard Billing, Danielle Oleda

Duggins, David Rubin, Robert Schwartz, Kiran G. Sonnad(CLASSE, Ithaca, New York), Stefano De Santis (LBNL, Berkeley,
California)

The Cornell Electron Storage Ring has been reconfigured as atest accelerator (CesrTA) with beam energies ranging from 2
GeV to 5 GeV of either positrons or electrons. Research at
CesrTA includes the study of the growth, decay and mitigationof electron clouds in the storage ring. Electron Cloud (EC)densities can be measured by resonantly exciting thebeam-pipe with microwaves. The EC density will change
beam-pipe's resonant frequency by an amount that is
proportional to the local electric field squared of the standing
waves. When the EC density is not uniform, it is especially
important to know the standing wave pattern in order to obtainan absolute EC density measurement. We will present ourcurrent understanding of this technique in the context of new
test sections of beam-pipe installed in August 2012. This will
include bench measurements of standing waves in the
beam-pipe, simulations of this geometry and recent EC density
measurements with beam.

method. The methods based on OTR fulfilling theserequirements were successfully applied in the recent tests. iii)
The development of the synchrotron beam diagnostics isfocused on design validation of the cryogenic BPM. In addition

employ multiple cathodes and combine their multiple bunchedbeams along the same axis. A proof-of-principle test bench will

system and double-slit interferometers are installed, and utilized

to measure the turn-by-turn beam profile, injected beam
oscillation, bunch length, and so on. An overview of these

Ikeda, John Walter Flanagan, Takaaki Furuya, Makoto Tobiyama(KEK, Ibaraki), Manabu Tanaka (MELCO SC, Tsukuba)

KEKB has stopped since June 2010 for upgrading the luminosity
40 times, i.e. SuperKEKB. During the operation of 11 years, apair of controlled beam abort systems worked more than 10000
times to protect the hardware components of KEKB accelerator
and the detector against the high intensity beams of LER and
HER. Optimization of the abort trigger was necessary to balance
efficient operation with the safety of the hardware. Therefore,
we analyzed one-by-one all of the aborts, and continually
adjusted the abort system. The diagnostic system was based ona high-sampling-rate data logger that recorded beam currents,
RF signals and beam loss monitor signals. The beam oscillation
signals, vacuum pressure and detector dose rate were also
examined. This paper describes the typical abort causes,
optimizations of abort levels, and abort statistics overapproximately eight years after having arrived at high beam
current operation.
TUPB54 The Radioactive Beam Diagnostics at LNS - INFN - Luigi

Cosentino (INFN/LNS, Catania)

At LNS - INFN Catania, two complementary facilities forRadioactive Ion Beams have been developed in recent years.
They exploit the two techniques known as Isotope Separation
On Line (ISOL) and In Flight Fragmentation, with a primary beam
accelerated by means of the LNS Superconducting Cyclotron.
EXCYT makes use of the ISOL technique to produce theradioactive beams, with an energy up to 7 AMeV. FRIBs uses the
In-Flight technique, with an energy up to 60 AMeV. The intensity
is well below to the levels of the standard stable beams, being
tipically below 10^6 pps. The standard beam diagnostics
cannot be used, because of the low signal to noise ratio. An
efficient beam diagnostics has been therefore developed andinstalled, well suited for our low intensity radioactive beams. It
permits an accurate check in real time of the beam, such as the
profiles, the intensity and the isotope identification along thebeam lines, thus allowing the optimization of the transmission
until to the experimental halls. The devices are based on
nuclear particle detectors, in particular on position sensitive
silicon detectors (PSSD), germanium detectors, scintillators andscintillating optical fibres.

TUPB55 S-band Timing Diagnostic at the LCLS - Dorian Keith Bohler(SLAC, Menlo Park, California)

Timing and synchronization at the LCLS is a multiple tiered
process with various hardware and software systems, which arefunctionally independent. This autonomy has resulted in timing
errors observed by LCLS users. Coherent laser timing jumps
have occurred during cycles of unlocking-locking the Femtolock
box. The software does not monitor the state of the Femtolock
and these jumps occur when the laser SPAC (on 476 MHz)rotates the reference phase larger than 350ps (one cycle of2856 MHz). A diagnostic was developed to accurately measure
the time difference between the timing fiducials and thebeam-induced signal from the toroids in the LCLS injector. Thisdiagnostic has a timing has 40ps and detects these timing
jumps as they occur.
TUPB56 MicroTCA.4: a New Standard for Diagnostics and Controls - Kay

MTCA.4 was released in Oct 2011 as a new standard based on
MicroTCA with extensions for rear IO and precision timing. The
MTCA.4 standard was driven by several accelerator labs
together with industrial partners within the PICMG. It provides ahigher degree of modularization compared to other crate
systems. Complex designs with FPGA interfaces to PCIe on thefront side of a crate can be interfaced by application specificsignal conditioning or processing on the rear side. Even highperformance RF front-ends could be implemented on a rear
module. And the new standard defines precision clock andtrigger distribution within a shelf. Furthermore, full remotemanagement on the crate and slot level is available. Diagnostic
electronics require a clean environment for sensitive signal
processing and high speed data transfers to cope withincreasing ADC sampling rates and fast feedbacks. High quality
and high performance of analog signal processing was recently
demonstrated. The highlights of the new MTCA.4 standard aswell as experience and results with the first systems in the field

TUPB62 Transverse Emittance Measurement using Slit-Grid - Min Li, Peng

Li, Ruishi Mao, Junxia Wu, Jingzhe Zhang, Yong Zhang, Tiecheng
Zhao (IMP, Lanzhou)

There are several ways to measure the beam transverse
emittance. In this paper, the slit-grid emittance measurement
device was proposed. The slit-grid is a one dimensional
emittance measurement device. During the measurement, theslit, driven by the stepper motor is moved stepwise across thebeam, and then the signal induced on the grid will be stored in
the computer for further analysis. Because slit-grid is one
dimensional device, two sets of this device are needed fortransverse measurement. In this paper, we introduce the design,
parameters, data acquisition and analysis for this measurement.
Especially the software integration is given in this paper. The
software development for emittance front-end control and data
analysis is based on the labview language. The slit-grid device

TUPB63 Development of Turn-by-turn Beam Diagnostic System using
Undulator Radiation - Mitsuhiro Masaki, Akira Mochihashi,Haruo Ohkuma, Shiro Takano, Kazuhiro Tamura (JASRI/SPring-8,
Hyogo-ken)

At the diagnostic beamline II (BL05SS) of the SPring-8 storage
ring, a turn-by-turn beam diagnostic system using undulator
radiation has been developed to observe fast phenomena suchas stored beam oscillations during the top-up injections,blowups of beam size and energy spread coming from theinstabilities of a high current single bunch and so on. The fastdiagnostic system observes a spatial profile of the undulator
radiation on a selected harmonic number. Especially, the higher
harmonic radiations than the 10th-order are sensitive to theenergy spread. A fluorescence screen (YAG:Ce) with afterglow
of several tens of nano-second converts the radiation profile
into visible light image. The imaging optics makes the horizontal
and vertical profiles as two line images by one-dimensional
focusing using cylindrical lenses. A fast-gated CCD camera withimage intensifier simultaneously captures the two line images.
The kinetics readout mode of the fast CCD camera is used toregister the spatial profiles of several tens of turns in one flame.
The principle and experimental setup of the turn-by-turndiagnostic system, and examples of beam observations will bepresented.

TUPB64 Methods to Reduce the System Error for High Power MSSWEmittance - Shi Xiang Peng, Jia Chen, Zhiyu Guo, Pengnan Lu[on leave], Haitao Ren, Yuan Xu, Zhong Xi Yuan, Jie Zhao
(PKU/IHIP, Beijing)

Recently a new Multi-Slit Single-Wire (MSSW) type high power
beam emittance meter named as HIBEMU-5 has developed in
Peking University (PKU). Compared to previous MSSW devices,
HIBEMU-5 greatly reduced the system error from 16.4% to 3.7%
by specific designs to solve the incomplete short-slit sampling
and fixed slit-wire distance. The problems of previous PKU
devices are analyzed in part one. In part two, we describe thespecific updating methods to solve its short-slit disadvantage by
re-designing a longer-slit board with sufficient cooling, detailthe mechanical scheme of changing the slit-wire distance fordifferent beam divergence. The commissioning results given atpart three prove that this new long slits design is successful tocomplete the beam sampling without being distorted by highpower H+ beam. And the movable wire cup is able to locate thebest measurement position for different beam focusing
TUPB65 Transverse-acceptance Measurement System for the JAEA AVF
Cyclotron - Hirotsugu Kashiwagi, Satoshi Kurashima, Nobumasa

Miyawaki, Okumura Susumu (JAEA/TARRI, Gunma-ken)

We are developing an acceptance measurement system toevaluate transverse phase-space matching of the emittance ofan injection beam to the acceptance of the AVF cyclotron. The
system is composed of a phase-space collimator in the low
energy section and a beam intensity monitor in the high energy
section. The phase-space collimator, which consists of two pairsof slits, allows very small-emittance beams to be injected into
the cyclotron by limiting position and divergence angle of thebeam from an ion source. The beam intensity monitor is used toobtain the ratio of beam intensity at the collimator to that at themonitor. In acceptance measurement, the small-emittancebeams at various positions in a transverse phase-plane are
injected to determine the distribution of relative transmission in
the phase plane. In preliminary tests, only a part of acceptance
was able to be measured because the injection-beam emittancefrom ion sources does not cover the whole acceptance. To
expand the measurement area, a steering magnet has been
added in the system. The magnet scans the injection beam inphase planes in synchronization with the acceptancemeasurement to simulate the large emittance.

TUPB66 A Beam Tail Monitoring System of a High Intensity Beam to theMain Ring of J-PARC - Kenichirou Satou (J-PARC, KEK & JAEA,

Ibaraki-ken)

We have established a real-time beam-tail monitoring systemusing long air ionization chambers (AICs) and collimators of thebeam transport line to the main ring of J-PARC. The collimators
remove the beam tail components outside the emittance of
54pi mm mrad for horizontal and 60pi mm mrad for vertical, and
the AICs identify the beam loss power at the collimators. The
intentional beam losses have been used to calibrate the AICs.
The output response showed good linearity up to the intensityof 8.4E11/batch, which amounts to 1% of the designed beam
intensity of 8E13/batch, and the estimated error was ±7%
which includes a dependence of beam loss points on thecollimators and the shot-by-shot beam fluctuations. The
calibration procedures and the performances of the system will
be described.

The beam intensity supplied by HIRF-CSR has a wide range,high-intensity primary beams and low intensity fragment-beams
in connection with the slow extraction and the fast
beam-extraction from the synchrotron CSRm. The detector (CG)
has been developed for the beam profile monitoring atradioactive beam line HIRFL-CSR. The front-end electronics are
based on CPLD controlled sample-and-hold circuits andmultiplexer. Remote control is used to tune the detector

TUPB69 Numerical Analysis on the Gain-reduction Characteristics ofMulti-wire Proportional Chambers - Ken Katagiri, Takuji

Furukawa, Koji Noda (NIRS, Chiba-shi)

Several MWPC (Multi-Wire Proportional Chamber) monitors are
installed to diagnosis the beam profiles in the high-energy beamtransport at HIMAC (Heavy Ion Medical Accelerator in Chiba)
synchrotrons. When the intensity of the incident beams aremuch high, the gain reduction of the output signal from the
MWPC monitor occurs due to the space charge effect ofpositive ions around the anode wires. The gain reduction is
expected to be improved by changing geometric parameters,such as anode radius and distance between electrodes. In order
to investigate the gain-reduction characteristics for different
geometric parameters, we performed numerical simulation
using a numerical code. The numerical code was developed
using a two-dimensional drift-diffusion model to evaluate thegas gain including the reduction effect caused by the spacecharge effect of the moving positive ions. We investigate thegain-reduction rate for several parameters of the anodedistance when changing the beam intensity. From these results,
we discuss desirable distances between the anode wires toimprove the gain reduction.

TUPB71 A New Low Intensity Beam-profile Monitor for SPIRAL2 - Jean-Luc

Vignet, Eloise Gueroult, Julien Pancin, Nicolas Renoux (GANIL,
Caen)

In order to obtain profiles of SPIRAL 2 ion beams, several
beam-profile monitors are presently being developed at GANIL.
One of them is a low-intensity beam-profile monitor that works
as a secondary electron detector. This Emission-Foil Monitor(EFM) will be used in the radioactive beam lines of SPIRAL2 andin the experimental rooms of this new facility. The ions produce
secondary electrons when they are stopped in an aluminium
emissive foil. The electrons are then guided in an electric fieldplaced parallel to a magnetic field in a double-stage
microchannel plate (MCP). A 2D pixelated pad plane placed
below the MCP is then used to collect the signals. The magnetic
field created by permanent magnets in a closed magnetic circuit
configuration permits the beam-profile reconstruction to beachieved with good resolution. The EFM can visualize
beam-profile intensities between only a few pps to as much as
10 9 pps and with energies as low as several keV. This profiler
has been studied since 2011 and will be manufactured in 2013.
For the signal acquisition, a new dedicated electronics system
will be employed. Recent results of this monitor and theelectronics will be presented here.

intensified CCD that can be gated on a single bunch or on abunch train for a stronger signal. The bright central stored beam
was obscured so the comparatively faint injected beam could
be observed. The injected beam comes in at a large enoughoffset so that it was clearly visible above any diffraction or beam

Ohsawa (Kyoto University, Kyoto-shi), Teruhisa Morimoto(Morimoto Engineering, Iruma, Saitama), Takashi Fujisawa,Takeshi Murakami, Koji Noda (NIRS, Chiba-shi)

A non-destructive beam profile monitor using a sheeted jet
beam of nitrogen molecular as a target has been developed forintense ion beams. The pressure of the sheeted molecular beam
was 5 x 10-4 Pa at the beam collision point. A light emitted fromexcited nitrogen by an ion beam collision is measured by a highsensitive camera with a radiation resistant image intensifier.
Verification of such a principle was already demonstrated with
low-energy ion beams[1]. In this paper, some actual designs forintense beams of the J-PARC MR will be discussed mainly as
bellow, intensity upgrade of the jet beam production,
configuration of the detection chamber and its apparatus

TUPB74 Diamond Mirrors for the SuperKEKB Synchtron Radiation
Monitor - John Walter Flanagan, Mitsuhiro Arinaga, Hitoshi

Fukuma, Hitomi Ikeda (KEK, Ibaraki)

The SuperKEKB accelerator, a 40x luminosity upgrade to the
KEKB accelerator, will be a high-current, low-emittance double
ring collider. The beryllium primary extraction mirrors used forthe synchrotron radiation monitors at KEKB suffered from heatdistortion due to incident synchrotron radiation, leading tosystematic changes in magnification with beam current andnecessitating continuous monitoring and compensation of such
distortions in order to correctly measure the beam sizes. The
heat loads on the extraction mirrors will be higher at SuperKEKB,
with heat-induced magnification changes up to 40% expected if
the same mirrors were used as at KEKB. We are working on adesign based on mirrors made of quasi-monocrystalline
diamond, which has much higher heat conductance and a lower
thermal expansion coefficient than beryllium. With such mirrors

photodiode module with a high frequency response of 1 GHz forthe visible ray. Signals from the detector were transferred to aspectrum analyzer. The beam profile was magnified strongly bya conventional profile monitor system. We scanned the beamprofile in vertical direction by shifting the detector. The

Igarashi, Dai Arakawa, Yoshinori Hashimoto, Masaki Tejima,
Takeshi Toyama (KEK, Ibaraki), Kotoku Hanamura (MELCO SC,
Tsukuba)Transverse beam profiles have been measured using flying wire
monitors at the main ring of the Japan Proton Accelerator
Research Complex. The wire target should be thin and the wirescan has to be fast for the precise profile measurement.
Otherwise the beam distribution would be disturbed and themeasured profile would not be accurate. We use carbon fibersof 7 μm in diameter and the scan speed of 10 m/s. The wire is
attached with an aluminum flame of 140 mm of the rotation
radius and rotated with a DC servomotor. A potentiometer is
attached to the wire flame and the angle readout is used for the
feedback of the servomotor and the wire position measurement.
The secondary particles from the beam-wire scattering aremeasured with a scintillation counter. Beam profiles arereconstructed by making the scatter plot of the scintillator
signal and wire position. Both horizontal and vertical flying wire
monitors have been used for the beam commissioning. We havesuccessfully measured the beam profile of up to 1.2×10^13

uniform ion beam formed by multipole magnets both precisely
and handily. A technique has, therefore, been developed tomeasure the two-dimensional transverse intensity distribution of
the ion beam using Gafchromic radiochromic films (Ashland
Inc.). In order to show available fluence ranges of the film, thecoloring response of the Gafchromic films irradiated withseveral species of ion beams is investigated as a change in the
optical density of the film. It has been found that the opticaldensity increases linearly with the fluence, whose range ispractical for materials and biological research. Thus, the relativetransverse intensity distribution of ion beams can be measured
using the film. Furthermore, the intensity distribution
determined by the Gafchromic film is compared with thearea-density distribution of track-etched pores in a polymer film
from a microscopic viewpoint. It has been demonstrated thatthe beam uniformity obtained from the Gafchromic film isequivalent to the relative standard deviation of the microscopic
pore distribution.

In future free electron lasers, electron and photon beam sizes
range between 10 um and a few millimeters. For an initial set upof the accelerator, to confirm target parameters for optics andemittance, and to optimize the FEL for different user requests,
the transverse profile of these beams has to be determined. A
monitor based on a scintillating crystal as well as opticaltransition radiation (for the electron beam) has been designed
for the SwissFEL project. It features a projected pixel size of 7
micrometers, a good resolution over a field of view of 6 mm x 15mm, a good sensitivity (as required for the low-charge mode of
SwissFEL) and a 100 Hz image readout. To test the monitor, it
has been installed at the SwissFEL Injector Test Facility, where
electron bunches between 10 and 200 pC can be generated. In
conjunction with a transverse deflecting cavity, the profile
monitor has been used to measure the time-resolved slice
emittance of these bunches.

Optical Transition Radiation (OTR) appearing when a charged
particle crosses an interface between two media with different
dielectric constants has widely been used as a tool fortransverse profile measurements of charged particle beams innumerous facilities worldwide. The basic tuning methods andoperation of conventional OTR monitors are well established fortransverse beam sizes not smaller than 3-5 um. Since the Point
Spread Function (PSF) dimension defines the resolution of theconventional monitors, for small electron beam dimensions the
PSF form significantly depends on a presence of OTR tails
diffraction and aberrations in the optical system. In our
experiment we have managed to squeeze the electron beamsuch that we can practically measure PSF distribution in one
direction. The revealed PSF structure is such that the visibility
depends on the transverse beam size on micron scale. We
developed an empirical calibration technique and successfully
overcame the resolution limit of the common OTR monitor
reaching sub-micron level. Here we represent the recent
developments and upgrades in both setup and data analysis ofa sub-micrometer electron beam profile monitor.

Beam loss measurement systems are often used for theprotection of equipment against the damage caused by

Increasing reliability often leads to more complex systems. The
downside of complexity is a reduction of availability, therefore
an optimum has to be found for these conflicting requirements.
A detailed review of selected concepts and solutions fromreal-life examples will be given to show approaches used invarious parts of the system from the sensors, signal processing,and software implementations up to the requirements for

WECC03 Intensity Imbalance Optical Interferometer Beam Size Monitor -Mark James Boland (ASCo, Clayton, Victoria), Toshiyuki
Mitsuhashi, Takashi Naito (KEK, Ibaraki), Kent Peter Wootton(The University of Melbourne, Melbourne)

The technique of measuring the beam size in a particle
accelerator with an optical interferometer with the Mitsuhashi
apparatus is well established and one of the only direct
measurement techniques available. However, one of thelimitations of the technique is the dynamic range and noise levelof CCD cameras when measuring ultra low emittance beams
and hence visibilities close to unity. A new design has beensuccessfully tested to overcome these limitations by introducing
a know intensity imbalance in one of the light paths of theinterferometer. This modification reduces the visibility in acontrolled way and lifts the measured interference pattern outof the noise level of the CCD, thus increasing the dynamic rangeof the apparatus. Results are presented from tests at the ATF2 at
KEK and on the optical diagnostic beamline at the Australian
Synchrotron storage ring.
WECC04 Analysis of the Electro-Optical Frontend for the New 40 GHz
Bunch Arrival Time Monitor System - Alexander Kuhl, Juliane

The Free electron LASer in Hamburg (FLASH) is currently
equipped with four Bunch Arrival time Monitors (BAMs) which
achieve a time resolution of less than 10 fs for bunch charges
higher than 500 pC (1). In order to achieve single spike FEL
pulses at FLASH, electron bunch charges down to 20 pC are ofinterest. With the current BAMs the required time resolution is
not reachable for bunch charges below 500 pC. Therefore new
pickups with a bandwidth of up to 40 GHz (2) are designed andmanufactured. The signal evaluation takes place with atime-stabilized reference laser pulse train which is modulatedwith an Electro-Optical intensity Modulator (EOM). The new
pickup system also requires a new electro-optical frontend witha 40 GHz EOM. The theoretical limits of the time resolution

Chair: Prapong Klysubun (SLRI)WECD01 Operation of a Single Pass, Bunch-by-bunch x-ray Beam Size
Monitor for the CESR Test Accelerator Research Program - NateRider, Michael Gerard Billing, Michael Paul Ehrlichman, Brian
Heltsley, Mark Alan Palmer, Daniel P. Peterson, David Rubin,James P. Shanks, Kiran G. Sonnad (CLASSE, Ithaca, New York),
John Walter Flanagan (KEK, Ibaraki)

The CESR Test Accelerator (CESRTA) program targets the studyof beam physics issues relevant to linear collider damping ringsand other low emittance storage rings. This endeavor requires
new instrumentation to study the beam dynamics along trains ofultra low emittance bunches. A key element of the program has
been the design, commissioning and operation of an x-ray beam
size monitor capable, on a turn by turn basis, of collecting single
pass measurements of each individual bunch in a train overmany thousands of turns. This new instrument utilizes custom,high bandwidth amplifiers and digitization hardware andfirmware to collect signals from a linear InGaAs diode array. The
instrument has been optimized to allow measurements with
3x109 to 1x1011 particles per bunch. This paper reports on theoperational capabilities of this instrument, improvements for its
performance, and the methods utilized in data analysis.
Examples of key measurements which illustrate theinstrument¿s performance are presented. This device
demonstrates measurement capabilities applicable to futurehigh energy physics accelerators and light sources.
WEID02 BIW 2012 Highlights - Kevin Jordan (JLAB, Newport News,

Virginia)

The final Beam Instrumentation Workshop, hosted by Jefferson
Lab, was held in Newport News Virginia, April 15 - 19, 2012.
The series of 15 meetings, spanning 23 years began at
Brookhaven National Lab, adopted the Faraday Cup Award torecognize excellence in particle beam diagnostics instruments,
and culminated in a transition to a 3 year cycle with DIPAC & a
new Asian meeting; the IBIC. This presentation gives highlightsof the spring meeting and a bit of nostalgia of the past events.

Thursday Session A, 9:00 – 10:10
Chair: Takeshi Toyama (KEK/J-PARC)
THTA01 Beam Position Monitors for Circular Accelerators - Shigenori

Hiramatsu (KEK, Ibaraki)

The electrostatic induction type beam position monitors (BPMs)
for circular accelerators such as proton synchrotrons andelectron accumulation rings will be discussed. Discussions on
the beam induced charge on the BPM pick-up electrodes, signal
detection systems, and techniques of beam based alignmentand beam based calibration will be given. For high beam current
machines, the evaluation of the beam coupling impedance of
BPM is an important issue to avoid the beam current limit bybeam instabilities caused by BPM impedances. Another serious
problem is the movement of BPMs by the thermal distortion of
the beam pipe by high power synchrotron radiation. These
problems will be also mentioned briefly.
Thursday Session B, 10:40 – 12:00
Chair: Seadat Varnasseri (ESSB)THCB01 E-Lens Test Stand Instrumentation Progress - Toby Allen Miller,

David Mark Gassner (BNL, Upton, Long Island, New York)In preparation for installation of an Electron Lens (E-Lens) into
RHIC, planned for the Fall of 2012, a working test bench is in
use testing performance of the gun, collector, instrumentationand controls. This paper will present the progress and pitfalls
encountered while testing & operating the instrumentation on
this test bench. Results are presented from issues including
ground loop signals generated by the DCCTs, static magnetic
field interference, competing YAG screen illumination
techniques, YAG crystal damage during beam operation,pinhole scan data correction for skew angle and scaling,
rendering of pinhole data into an image file, performance of thefour quadrant beam scraper electrodes, and challenges inmeasuring beam current in the power circuit. Working
knowledge and insight into each of these systems has been
gained by both success and difficulties leading to success.
These insights will be presented with supporting data andimages.

THCB02 Twisting Wire-Scanner - Vahagn Gharibyan (DESY, Hamburg)
A new type of 'two-in-one' wire scanner is proposed. Recent
advances in the linear motors' technology make it possible tocombine translational and rotational movements. This will allow
to scan the beam in two perpendicular directions using a single
driving motor and a special fork attached to it. Vertical or
horizontal mounting will help to escape problems associatedwith the 45 deg scanners.
