Dear colleagues,
the Workshop on Accelerator Operations was founded in 1996 as a platform of communication for
operators and operations managers of particle accelerators around the world. Since then theworkshop has been held at different laboratories and has developed a rotation scheme between
Europe, Asia and the Americas with one workshop every two years. WAO2014, the ninth workshop of
this series, will now take place in Mainz, Germany, jointly hosted by GSI/FAIR, HIT and DESY.

WAO2014 provides a unique forum for experts and novices to share their experience and to
exchange information and ideas in the field of accelerator operations. The workshop aims to provide
an atmosphere that fosters lively discussions about the operation of particle accelerators worldwide,
ranging from low energy machines over synchrotron radiation facilities to high energy, high intensity
hadron accelerators and colliders. Topics of the workshop include control room design, softwaretools, safety aspects, operator training and motivation, shiftwork, accelerator maintenance andreliability, user satisfaction and other aspects of operating a big, expensive and in most cases uniquesystem like an accelerator.

Both the International Program Committee and the Local Organizing Committee welcome you to
Mainz and we hope that you will have a good time at WAO2014.

Monday Oral Presentations
Session: How we do Business, New LabsCYCLOTRON PRODUCTION OF SPECT ISOTOPES
Jozef Orzechowski, TRIUMF
Tri University Meson Facility (TRIUMF) is located on the University of British Columbia territory. The NORDION
Vancouver Operations (VanOps) facility is located on the TRIUMF site and is focused on the production of
medical radioisotopes using cyclotrons. The unique symbiotic relationship between a scientific laboratory andcommercial company will be explained. The equipment used for isotope production comprises a CP-42 and two
TR-30 cyclotrons in addition to two beam lines (~100 and ~500 MeV) from the TRIUMF 500-MeV cyclotron. The
radioisotopes produced at TRIUMF/NORDION VanOps include Ga-67, Sr-82, Pd-103, In-111, I-123, and Tl-201.
These are produced as follows. Ga-67 (t1/2 3.26 d) is produced on a TR-30 cyclotron. Sr-82 (t1/2 25.55 d) is
produced on an ~100 MeV beamline from the TRIUMF 500-MeV cyclotron. Pd-103 (t1/2 16.99 d) is produced
on a TR-30 cyclotron. In-111 (t1/2 2.80 d) is produced on a TR-30 cyclotron. I-123 (t1/2 13.2 h) is produced on
CP-42 and TR-30 cyclotrons. Tl-201 (t1/2 3.04 d) is produced on a TR-30 cyclotron.

OPERATION OF THE ATLAS SUPERCONDUCTING ACCELERATOR*†
Matthew R. Hendricks, ANLATLAS (the Argonne Tandem Linac Accelerator System) is a super conducting heavy ion accelerator which canaccelerate nearly all stable, and some unstable, isotopes between protons and uranium, with a charge to mass
range of 1/1 to 1/7. The maximum energy ranges of these accelerated ions are 7-17 MeV per nucleon withintensities ranging from sub-picoampere to microampere currents. Recent additions to the facility include,
CARIBU (neutron-rich fission fragments from a one Curie-252 Cf source for charge breeding and acceleration), a
60 MHz CW radio frequency quadruple, as well as energy and intensity upgrade cryostats. On average ATLAS
delivers a different ion species and energy each week to one of six target areas. ATLAS currently operates 24hours a day, 6 days per week, with 7 days per week planned. Topics discussed will be how we handle day to day
operation of the facility including start up, troubleshooting problems, maintenance, ion beam tuning methods
for intensities below ammeter detectable currents, and diagnostic tools used for unstable beam transport.

THE LINAC COHERENT LIGHT SOURCE (LCLS) FREE ELECTRON LASER (FEL) PERFORMANCEPROGRAM, WITH FOCUS ON REPRODUCIBILITY
William Colocho, SLAC
This talk will describe the current performance improvement program of LCLS. It will describe how machinetime is partitioned to accommodate beam time requests from different groups. Machine time is allocatedfor User delivery, configuration preparation for future users, FEL performance program, preventive
maintenance, installation of new instrumentation and control software testing. The talk will present inmore detail the FEL performance improvement program and then focus in more detail on reproducibility
issues of LCLS FEL at SLAC National Accelerator Laboratory. A significant amount of machine time is spentin configuration preparation; a good fraction of this time could be recovered by achieving a more
reproducible X-ray laser system.

Session: New Control Room Technologies
THE FULLY DIGITAL PSI ACCELERATOR CONTROL ROOM
Andreas Luedeke, PSI
The Paul Scherrer Institute operates four independent accelerator facilities from one common control room
since 2007. All beam signals are digitized locally at the accelerators, no analogue signal cables are going into thecontrol rooms. All accelerator facilities are operated by one team of operators, everyone being trained on allmachines. We'll present the technical and administrative solutions that contributed to the success of ourcommon control room.

NEW CONTROL SYSTEM OF PLS-II
MunGyung Kim, PAL
PLS-II has been upgrade from PLS (Pohang Light Source) from 2011. There are several important changes.
At first electron beam energy changed from 2.5 Gev to 3.0 GeV. Operation mode was changed from decay to
top-up. RF systems in the storage ring were changed form 5 normal conducting cavities to 3 superconducting
cavities. Two times of insertion devices than PLS were installed. These means we need a new control system tocontrol them with more high accuracy and safety. Furthermore we wish operator and user friendly systems,
specially using mobile phones. During the last three years we have developed the control systems step by stepin these aspects. So this paper introduces a new control system of PLS-II in these aspects.

PROGRESS TOWARD A NEW CONTROL ROOM FOR THE SLAC ACCELERATORS
Michael Stanek, SLAC
We are constructing a new control room at SLAC to unify and improve the operation of the LCLS, SPEAR3, and
FACET accelerator facilities, and to provide the space and flexibility needed to support the LCLS-II accelerator
when it is ready for commissioning. The existing control rooms for the linac and SPEAR3 have been upgraded invarious ways over the last decade, but their basic features have remained unchanged. The new Accelerator
Control Room (ACR) in the new Research Support Building (RSB) will be larger and have features better
matched to the evolving needs of the accelerators. In this paper, we describe the status of this project and theplans for the months ahead.

OPERATING EXPERIENCE WITH THE NEW RHIC CONTROL ROOMPeter Ingrassia, BNL
After six years of planning and construction RHIC operation began in the “third generation” control room in
January 2012. This presentation will review the goals for the project; the parts of the design that did and did notwork; the challenge to obtaining beneficial occupancy; new technologies employed; the modifications that havebeen made since 2012; and the overall level of customer satisfaction with the result.

Session: Happy User’s Index – Customer Satisfaction
A COMMON OPERATION METRICS FOR 3rd GENERATION LIGHT SOURCES
Montse Pont, ALBAHigh reliability is a very important goal for third generation light sources. Very often the beam availability andthe mean time between beam outages is used as an operation metrics to measure the reliability of therdaccelerator. A survey at different 3 generation light sources revealed that the calculation of the beam
availability and the mean time between beam outages does vary significantly between facilities. This does
prevent a useful comparison of the reliability of these accelerators. The authors propose a specific metrics forthe reliability of 3rd generation light sources; a metrics that will allow a detailed and meaningful comparison ofthese particle accelerators.

OPERATION PROGRESS AND UPGRADE IN SSRF
Qinglei Zhang, SINAP
Shanghai Synchrotron Radiation Facility (SSRF) has been opened to users since May2009, and theperformance has been improved continuously to satisfy their needs. Accelerator failure analysis and solution
study has been progressing, and the failure rate was reduced significantly. Some experience was summarized
and would be helpful for operation in future. Several new beamlines were under commissioning. The new
insertion devices had brought some problems in operation, such as injection difficulty and life timedecrease, which was unfavorable to users. Much time and effort has been devoted to restore the beam
dynamics and synchrotron quality. Close orbit stability was under control with feed forward system, which was
also an important aspect for users.

LHC MACHINE AVAILABILITY & LUMINOSITY PRODUCTION
Georges-Henry Hemelsoet, CERN
The performance of particle colliders is often quantified by the key figures of beam energy, instantaneous
luminosity, and importantly integrated luminosity. This talk will describe how we optimize the different
parameters to maximize both the instantaneous and integrated luminosity. The beam energy is generally
fixed at the beginning of the year. Good machine availability is critical for integrated luminosity production
and fault analysis, maintenance, careful planning, injection readiness and turnaround time all contribute tomeet the experiments’ demands for massive event production. We will describe the specific challenges that
Operation has to face in order to maximize the time in physics.

TAILORING THE ESS RELIABILITY AND AVAILABILITY NEEDS TO SATISFY THE USERS
Enric BargallÓ, ESS
ESS is a neutron source facility that will serve the scientific community by delivering spallation neutrons to asuite of scientific instruments where scientific users will be able to perform neutron scattering experiments. Asa user facility, ESS must tailor its specifications and its future operation to satisfy the needs of the users andtheir experiments. Reliability and availability are key metrics for achieving the scientific vision of the ESS. To
define these metrics, some specifications in terms of possible degraded modes of operation andconsequences of the different possible events on the experiments have to be defined. The goal of thiscontribution is to describe the different kind of experiments expected at ESS and their needs in terms ofneutron beam performance: reliability, availability and quality. The implications on the reliability andavailability requirements will be described as well as the work being done to analyze and achieve such goals.

Session: Operating a SC Machine
OPERATION OF SUPERCONDUCTING ITEMS IN BEPCII
Jun Xing, IHEPThe Upgrade Project of Beijing Electron Positron Collider, BEPCII, applied superconductivity in the RF cavities
and magnets including the final focusing magnets and detector solenoid. A cryogenics system was set up toaccommodate these superconducting elements. Also there are control, power supplys and protection parts torunning the superconductor RF cavities and magnets. This talk will provide an overview of the operation status
and improvements on the superconducting items in these years. The limitations and puzzles are also discussed.

AN OVERVIEW OF CRYOGENIC OPERATIONS AT ESSJohn Weisend, ESS
The European Spallation Source (ESS), currently under construction in Lund, Sweden will be a world class centerfor neutron science. Cryogenics is a key technology for the ESS providing cooling for the superconducting RF
cavities in the accelerator, for the 16.5 K hydrogen moderator and supplying liquid helium for the neutron

11

instruments. This talk will give a brief overview of the ESS cryogenics system, describe planned operating
scenarios and staffing. It will also address reliability, turn down capacity and the planned control system.

COMMISSIONING AND FIRST YEARS OF OPERATION OF THE SARAF PHASE-I LINAC
Leonid Weissmann , Soreq, NRC
Phase I of the Soreq Applied Research Accelerator Facility (SARAF) should accelerate 2 mA protons anddeuterons CW beams at energies up to 4 and 5 MeV, respectively. These specifications were achieved only
partially. Nevertheless the facility is in active use since 2010. The status of the main accelerator components
and their major improvements are reported. Operation experience accumulated during the recent years will besummarized. The latter includes acceleration of up to 2 and 1 mA CW protons beam at energies 2 MeV and3.7 MeV correspondingly and operations of pulsed deuteron beams at energies up to 5.6 MeV. Someexperiments with high power beams on specially designed beam dumps and exotic targets, including the liquid
lithium jet target, will be briefly presented. The further improvements in operation of the current facility andplans for the future Phase II of the SARAF linac are discussed.

Tuesday Oral Presentations
Session: Software Tools incl. “Remote Operation”
CURRENT STATUS OF WEB APPLICATION FOR RIBF ACCELERATOR OPERATIONS
Akito Uchiyama, RIKEN
To provide the world's most intense radioisotope (RI) beams over the whole range of atomic masses of heavyions, the RIBF project has been started at RIKEN. The control system of RIKEN RIBF adopted the EPICS(Experimental Physics and Industrial Control System) that used LAN-based protocols and was constructed on
its own network. For RIBF control system, Web technology is used for applications of variety purpose, because
it has advantages for the following reasons: platform-independence, rapid system development, and ease of
system maintenance. Especially JavaScript and HTML provide a simplified, rapid method of creating dynamic
Web content, such as AJAX technology. Therefore, we developed AJAX-based Web applications for accelerator
operation tools such as electronic log notebook, operational log system, and data archive viewer. On the other
hand, we have also designed WebSocket-based operator interface to improve interactive performance on the
Web browser. WebSocket is a new protocol provided by the Internet Engineering Task Force (IETF) for
Web-based systems. In this workshop we will report the system implementation and the current status for RIBF
operation in detail.

MODEL-DRIVEN CEBAF SETUP AFTER THE 12 GeV UPGRADE
Dennis Turner, JLAB
For the 12 GeV upgrade, improvements in agreement between the CEBAF model and machine performance,along with new software tools and processes, were implemented such that new machine configurations canbe set from the model with less tune time. Over the course of 12 GeV CEBAF commissioning, these new tools
and processes were tested and improved upon. The result was a measurable reduction in necessary time fornew machine configurations. This talk will discuss the new tools and processes and compare with those of the
6 GeV CEBAF era.

THE FAULT ANALYSIS TOOL FOR THE ISIS ACCELERATOR
Julian Brower, ISISFLD 3 years on. The PC/Wi-Fi based interactive fault analysis tool and technical knowledge base system, for use
by ISIS accelerator Operation crew members. By using valuable time efficiently and effectively, FLD aims todecrease the response time to resolve equipment faults. FLD guides the crew through a hierarchical fault flow
chart at the point of need, providing all the information to drill down to failure modes. FLD, with over 40
engineering contributors (Equipment Owners) on board, has grown organically to incorporate many ISIS
accelerator systems and equipment. Three years on, we can now report our encouraging findings for saving
down time. We will show how we overcame challenges and gained the trust and support of our stakeholders.

SOFTWARE TOOLS FOR THE ATLAS SUPERCONDUCTING ACCELERATOR*†Maria Power, ANLAt ATLAS (the Argonne Tandem Linac Accelerator System) several software tools are utilized by theoperations group in order to assist in the operation of the accelerator. One such tool is the Operators
Notebook, which includes a shift log, experiment up and downtime tracking, and equipment tracking. A
second tool, called Paradox, archives the equipment control settings from running experiments and allows
them to be optionally scaled and loaded back into the accelerator control system for other experiments. In
this paper, I will discuss these and other tools used at the facility to assist in the accelerator operations.

13Session: Automation without Losing Skills
AUTOMATION AT THE CERN SUPER PROTON SYNCHROTRONJames Ridewood, CERNThe CERN Super Proton Synchrotron (SPS) machine has evolved into a truly multi-cycling, multi-clientmachine which has meant that changes to machine state are significantly more frequent than was once thecase. To maintain efficiency, several often-repeated tasks have been automated (access preparations, beamline
steering, automated economy settings, software interlock systems). This presentation will explore some of
the automation systems used by operations at the SPS complex, and will address some of the advantages
and disadvantages that automation brings. Examples of how and where automation is used in the SPS will
be demonstrated along with some potential future improvements and other areas where automation could beof benefit. The relationship between operations personnel and their machine will be examined and how
increased use of automation may affect this relationship.

THE AUTOMATION OF THE SEQUENCING OF ACCELERATOR CYCLES AND EVENTS AT FERMILAB
Stanley Johnson, FNALThe accelerator complex at Fermilab has evolved over the years to include many different accelerators, beamlines, and modes of running. The various modes of running or accelerator cycles need to controlled andsequenced for safe and efficient operation of the accelerator complex. This control is provided by a device
called the “Timeline Generator”. This talk will look at the past, present, and future of this device. In particular,
this talk will look at how setting up this device has become more automated during the evolution of both thesoftware and hardware components. The talk will also include a discussion of how the automation affects
operators and knowledge of the system.

SEMI-AUTOMATIC BEAM ADJUSTMENT USING MIRKO AT GSI/FAIR
Stephan Reimann, GSI
At all accelerator facilities many tasks are going the path of increasing automation. At GSI the interactive
ion optics application MIRKO is used to adjust optical settings and semi automatically adjust the beam
position within transport lines. This talk will present the use cases for operators and the problems withinterpreting their results. In this context it will be shown, that this kind of automation leads in fact to a gain in
efficiency but also holds some pitfalls, which are important to avoid. On one hand there is the simplification, on
the other hand still the need remains to understand the underlying technical and scientific concepts.

Session: Operator Training – Online Lectures
OPERATIONS MACHINE SIMULATOR
Adrian Johnson, DIAMOND
The ever increasing emphasis on machine reliability and minimising number of trips and downtime means thatexisting Operators are actually operating the machine less and less frequently, and new Operators have very
little hands on machine time for learning. To provide a tool which can be used by Operators for training andpractice we have started development of a machine operations simulator. The simulator is based around asingle EPICs soft IOC with python ‘process’ scripts simulating the behaviour of machine sub systems and python
GUI scripts for control and parameter read back. The simulator is modular in construction so that more subsystems and more complexity and realism can be added piece by piece.

OPERATORS TRAINING EXPERIENCE AT THE ALBA SYNCHROTRON LIGHT SOURCE
Ferran Fernandez, ALBA
Since the ALBA synchrotron light source started operation with users on May 2012, up to five new operators
have joined ALBA and have been trained. A program has been established to train the new operators from14

scratch in about six to nine months. The training is divided in five steps. First, there is a set of lectures about the
ALBA accelerators and its sub-systems, which include assignments marked by the different lecturers. Second,
there is a set of lectures and hands-on training on the operational procedures, which cover everything fromnormal operation to troubleshooting and common repairs. In the third step the trainees discuss different
failure scenarios proposing how the failure should be solved. The 4th step is dedicated to radiation safetyincluding an official course required by the Spanish radiation regulatory agent. And finally, the trainees go into
the control room to accumulate hours of hands-on training. The experience with this training program will be
discussed.

HOW TO FIND BEST PRACTICES FOR OPERATOR TRAINING
Andreas Luedeke, PSI
At all accelerator facilities operators needs training. But how is this training organised? How much effort isnecessary until an operator can safely operate the machine? Are there best-practices that could be applied tothe training of operators for a variety of different facilities? We did a survey of 17 different accelerator facilities
to find answers to these questions. This contribution will evaluate the results of the survey and present someideas on how we could collaborate for the benefit of our operator training.

TRAINING THE CONTROL ROOM ACCELERATOR PHYSICISTS
Isadoro “Terry” Carlino, JLab
Re-training control room staff after a major accelerator upgrade is already a considerable challenge, but add inrequired training for Accelerator Physicists, a limited training development budget, and no training-tracking
mechanism, and the task becomes even more daunting. Using “Just-in-Time” training provided by System
Experts and existing on-line training, two different training paths were created: one for Accelerator Operators
and another for Accelerator Physicists. Content was developed and stored on an independent server, while
tracking of course completion was done using the already-established Jefferson Laboratory Training
Department database.

Session: Operator Issues, Motivation, Managing OPs
OPERATOR ROLES AT THE AUSTRALIAN SYNCHROTRON LIGHT SOURCEDon McGilvery, SLSAThe Australian Synchrotron schedules over 5000 hours of user beam each year as well as 2000 hours ofmachine development and physics. This requires 24/7 Operator support. Since transitioning to Top Up
operation and the installation of a UPS for the storage ring, the Control Room functions have become muchless demanding. How to keep the Operators Motivated? Using a combination of creative shift rostering, theirinvolvement in projects matched to their skills and interests and by extensive training to provide “Expert Out of
Hours Support” to Beamline Users, are we providing a challenging but satisfying work environment for our
Operators?

MAINTAINING A VIABLE OPERATIONS GROUP; MOTIVATING AND MANAGING OPERATORSPeter Ingrassia, BNL
Retaining operators has always been a challenge for operations managers. One might say the challenge tends
to increase with time given, for example, changing budgets, a new mission, an increase in complexity ofoperation, or added responsibilities for the group. Reducing the challenge is not entirely deterministic – someluck is involved. Each operations manager has strong opinions regarding methods used to meet the challenge.
This presentation will summarize some of the lessons learned while attempting to manage the challenges
during more than two decades at the AGS-RHIC complex with the hope that it will spark an open discussion by
the workshop attendees and encourage them to share their positive and negative experiences.

DATA SUPPLY OF ACCELERATOR DEVICES – HANDLING A HUGE AMOUNT OF DEVICE PROCESS DATAAT A MEDICAL ACCELERATOR
Michael Galonska, HITThe Heidelberg Ion Therapy Facility (HIT) is the first dedicated proton and carbon cancer therapy facility inEurope. It uses full 3D intensity controlled raster scanning dose delivering method of pencil beams provided
by a linac-synchrotron-system to four high energy beam lines including a 360° rotating heavy ion gantry. Eachbeam line combination, i.e. a combination of the three ion source branches and treatment rooms isrepresented as a virtual accelerator (VAcc) within the control system. For each VAcc and for each ion kind(C, p, O, He) the device settings for all energy steps (255), beam sizes (4), intensities (10), and gantry angles(36) -making up for more than 100,000 possible settings- have to be provided by the control system. This
contribution outlines some issues of the data supply and data handling of this huge amount of device input
and process data at HIT from an operator’s point of view. That is the operator’s database interfaces and tools
which display the device settings and in particular its change history, and the backup and restore functions ofdevice settings according to the strong quality needs of medical treatment.

UPGRADING ELECTRONIC LOGBOOKS TO THE 21st CENTURY
Gregory Marr, BNL
The Collider-Accelerator Complex at Brookhaven National Laboratory converted from paper to electronic
logbook records in 2001. Since then our “elog” system had only 2 revisions, without much more than cosmeticchanges for the end user. This past year the Operations group collaborated with our Controls division for amajor update to our elog system, addressing many of the deficiencies found in our old elog package. Creating
and introducing a new interface has not been without difficulty. Our goals, progress and challenges will bepresented here.

THE AUSTRALIAN SYNCHROTRON ELECTRONIC LOG BOOK
Don McGilvery, SLSA
Since commissioning, the Australian Synchrotron has kept all operational logs in electronic form. Due to many
shortcomings of other Log books the Operators have developed a comprehensive Web based log book in house.
The eLog has standard features of formatted text and graphics, cut and paste capability, embedded objects
such as video, hot links and annotations. Regular entries such as shift summaries, beam dumps and operational
dropouts are auto-filled into standard templates. Facility statistics on uptime, faults, MTBF, MTB and others areauto generated and available on line. Over time its use has extended to all beamlines, engineering, technicaland safety groups. Having a single searchable repository of information for systems across the facility has
enabled the Operators to provide invaluable after hours support for beamlines and support systems. Having
detailed logs and statistics from day one has proven invaluable for tracking machine performance and directing
budget expenditure to drive facilty improvements.

MAJOR EVENT REPORTS
Chris Wetton, CERN
In the event of an incident, or Major Event, it is important that all relevant information be recorded so thatmeasures can be taken to reduce or prevent further incidents. At CERN, the responsible for creating thesereports are the TI operators, who record the events directly related to the incident before a validation by the
CERN hierarchy. The original tool that we had as part of our logbook was complicated to use and resulted in a
lot of wasted time and frustration on the part of the TI operators. With the move to a new version of thelogbook, we simplified the data entry process and, with a slight modification to the approval process, weallowed the other concerned groups to add more details to these reports. This presentation will show some of
the modifications that were made to the reporting procedure and how we resolved some of the problems that
we had, resulting in a much more efficient report with greater control over the confidentiality of restricted16

information. Whilst a great improvement over the old tool there are still some issues that we want to improveupon on, and new features that we will add in a newer version of the tool to be implemented with an updated
logbook.

EXPERIENCES FROM USING A SHIFT REPORTING TOOL IN ADDITION TO THE ELECTRONIC LOG BOOK
AT THE HEIDELBERG ION BEAM THERAPY CENTER
Klaus Höppner, HITThe HIT (Heidelberg Ion Beam Therapy) center is the first dedicated European accelerator facility for cancer
therapy using both carbon ions and protons, located at the university hospital in Heidelberg. It provides threefully functional treatment rooms, two with fixed beam exit and a rotatable Gantry. In early 2014, we
introduced a web based shift reporting tool for accelerator operations. Its aim is both to support accelerator
operations by documenting error messages of devices, read automatically from the control system’s Oracle
database and enriched by the operator’s comments, as to document changes to device settings andconfigurations that require additional checks and verifications that are part of the quality assurance guidelines
of a medical accelerator. The tool is based on the Python based CherryPy web framework, using SQLAlchemy
for object relational mapping and jQuery to provide a desktop like look and feel. It is also integrated with thewell established Wordpress based electronic log book used at HIT. We will present the software architecture of
the shift reporting tool and report on the experiences and lessons learnt after about half a year of operation.

2nd GENERATION ELECTRONIC LOGBOOK FOR FERMILAB ACCELERATOR DIVISION OPERATIONSDEPARTMENT
Duane Newhart, FNALThe Operations Department converted from a paper logbook to an electronic logbook on March 10th, 1998. 15
years 3 months and 12 days later we launched our 2nd Generation of electronic logbook. What prompted thechange after so many years? This presentation will cover the purpose for the change; the production anddevelopment of the 2nd generation electronic log. Provide an overview of the performance of the 2nd
generation elog to date, in addition to a wish list for the future.

INTUITIVE CONCEPTS FOR HUMAN-MACHINE-INTERACTION (HMI) IN ATTENTIVE ENVIRONMENTS
Michael Voit, TU Dortmund
Intuitive human-machine interaction requires the computer to recognize the context and intention of therespective user. In everyday face-to-face encounters, humans rely heavily on visual information, in order tograsp as much context information regarding their surrounding and dialog partner. With recent advances incomputer vision, this perceptual capability can be implemented technically, and the deduced situation
awareness can be beneficially used for innovative and intuitive user interfaces.
This presentation gives an overview of the advances at Fraunhofer IOSB for enhanced user interfaces withvision-based perceptual components. The advances are emphasized by recent project use cases, in whichprevailing interfaces were upgraded to perceptual interaction modalities for user-friendly and intuitive input
solutions.

Session: Radiation Safety Tasks done by Operators
OPERATORS PERFORM ROUTINE RADIATION MONITORING TASKS AT JEFFERSON LAB
Anna Shabalina, JLAB
Jefferson Lab does not have a 24/7 on-site radiation control group presence, so accelerator operators aretrained to perform some routine radiation safety duties. All operators are required to complete Assigned
Radiation Monitor (ARM) training, which includes five days of in-class training, a practical exam, and a written
exam, all administered by the Radiation Control Department. After completing the training, operators canperform tasks such as radiation surveys, filling out and filing survey maps, providing escorted access toradiologically controlled areas, monitoring and troubleshooting area radiation monitors, conducting beam
enclosure pre-release surveys of tools and materials, and performing weekly source checks of the survey

17equipment. This paper details the motivation for this program, the required training, lessons learned, types oftasks performed by operations staff, and types of tasks operations staff are not allowed to perform.

OPERATOR ROLES AND RESPONSIBILITIES FOR RADIATION SAFETY AT THE ADVANCED LIGHT
SOURCETom Scarvie, LBL
At the Advanced Light Source, Operators play a fundamental role in accelerator radiation safety. Accelerator
Operators are directly responsible for ensuring that radiation levels in the accelerator complex and on theexperimental floor are kept As Low as Reasonably Achievable (ALARA). Floor Operators are responsible forcontrolling all work involving beamline shielding and ensuring that all beamline work is carried out safely andwithin our regulatory and procedural framework. This presentation will include an overview of radiation-­­related Operator duties, a discussion of the tools they use to carry them out, and examples of past radiation
incidents and the roles Operators played in them. The beamline shielding control methods in use at the ALS will
also be presented, and some of the challenges involved in safely controlling the work of a diverse set of
beamline personnel will be highlighted.

LESSONS LEARNED FROM NSLS-II LINAC COMMISSIONING
Raymond Fliller, BNL
The NSLS-II linac was commissioned in the spring of 2013. During the final stages of commissioning, a weakness
in the existing shielding was discovered which allowed unwanted radiation in the NSLS-II booster tunnel, which
could have resulted in unexpected exposure. A subsequent investigation of the incident revealed a number ofareas in our conduct of operations which required improvement. In this paper we briefly discuss the event, thelessons learned, and our response to it. These lessons have application to facilities within the Dept. of Energy
complex and facilities worldwide.

SAFETY IN MODERN PARTICLE ACCELERATORS: THE ROLE OF CONTROL ROOM OPERATORS
Pierre Ninin, CERN
The safety of personnel in charge of the maintenance of last particle accelerator generations relies on thetreatment of huge amount of information and operational conditions intended to avoid the accidental
exposition of humans to radiations or other dangers. The latest risk assessment for CERN site highlights anincreasing of risks for personnel deriving particularly from co-activities carried by different teams of technicians
inside the classified areas. Personnel safety is then granted via two complementary means: an automatic
Personnel Protection System (PPS) and the human supervision of control room operators. From one hand, the
PPS is in charge of automatically performing a predefined set of Safety Instrumented Functions preventing thepresence of personnel inside areas where a potential dangerous event may occur. From the other hand control
room operators are responsible for coordinating the various activities for avoiding operational dangerous
modes for the personnel. In this context, one fundamental question needs to be answered: what is the
optimum balance between PPS automated tasks and the ones carried out by operators? This paper analyses thereturn of experience gained on this subject after several years of operation of LHC PPS and during therefurbishing of the PS Accelerators Complex PPS.

Wednesday Poster Presentations
RELIABILITY MONITORING FOR CUSTOMER SATISFACTION
Inokuchi Hiromi, NIRS
We believe that most important factor for customer satisfaction is to supply stabilized beam without trouble.
In other words, the role of operation and maintenance for accelerator is to minimize the occurrence of trouble
during operation and the downtime for recovery. To achieve the goal, NIRS, National Institute of Radiological
Sciences, in Japan has just started to monitor the performance of accelerator with parameter of Availability,
Failure Rate and Human Error as a User’s happy index. All troubles that occurred in a month are listed withcause of trouble, defective part and downtime to calculate above parameters. Those parameters are graphed
to monitor the trend. Also, defective parts are categorized and graphed for more breakdown information.
Human errors are classified to three stages, Level 0 for low risk and Level 2 for highest risk. The quality review
meeting is held every month. If a parameter of trend shows low quality, cause would be investigated andcorrective action would be discussed in the meeting. We had experienced the number of 82 near-miss(level 0)
errors in the last fiscal year, and about 50% of errors were caused by the fact that persons having within one
year experience lack some prerequisite knowledge. As a result of this analysis, we have reviewed and improved
the training program for new face, also modified the classroom training to be performed by two instructors thisyear. While one instructor is lecturing, the other instructor is taking care of the person who has a poor
understanding of the lecture at the same time. Therefore, we expect positive effect s from this improvement inthis year.

KEEPING SHIFT OPERATORS UP TO DATE
Adrian Johnson, DIAMOND
The Operator shift patterns at Diamond include whole weeks of normal 9 to 5 ‘off shift’ days, which provides
holiday and emergency cover. To provide the ‘off shift’ operators with relevant, timely and concise information
we have developed a number of tools. These range from web based tools for viewing information on smart
phones to large displays in the control room. Operator experience has shown that keeping up to date via thesetools makes for shorter easier handover sessions and less chance of important information being missed or lost.

SOFTWARE INTERLOCK SYSTEMLouis Pereira, CERNThe Software Interlock System (SIS) was introduced to protect the SPS (Super Proton Synchrotron) complex,
mainly for some areas of the SPS ring and extractions areas in 2005. SIS protects the machine throughsurveillance and by analysing the state of various key devices and dumping or inhibiting (timing system) the
beam if a potentially dangerous situation occurs. Being a part of the machine protection, and reach the final
operational state targeting LHC (Large Hadron Collider) in 2007. The system, which was designed with the useof modern, state-of-the-art technologies, proved to be highly successful and very reliable from the very
beginning of its existence.

OPERATOR DEVELOPED CONTROL & ANALYSIS TOOLS
V. J. Winter, DIAMOND
As operational conditions of a particle accelerator evolve, the tools used to control it need to be developed andadapted. Technical groups provide detailed access and control of system parameters that may not be
optimised for ease of use, clarity and fit for purpose for when dealing with 24/7 operation or repetitive tasks.
Operators have developed tools for simultaneous control of multiple insertion devices & beamline front ends,
which both bring together existing parameters from different machine areas and add control scripts in python.
Additional tools focus on analysis such as comparing back-up parameters with the current machine settings orextracting machine protection interlock data from a data archive in a human readable format. By being
produced by the operators for the operators they have the benefit of developing operational group knowledgeof systems as well as being relatively easily and quickly developed if business needs demand.

OPERATION OF SCANNING IRRADIATION SYSTEM AT NIRS-HIMAC
Yuji Tachikawa, NIRS
Three-dimensional scanning irradiation system has been utilized for treatment since 2011 at Heavy Ion Medical
Accelerator in Chiba (HIMAC), in the National Institute of Radiological Sciences (NIRS). The scanning irradiation
requires strict checking for beam position, size, range, and spill shape, because any changes in thesecharacteristics of beam will cause a significant impact on the irradiation dose. Therefore, the operators
perform the regular quality assurance (QA) checks for the therapeutic beam, daily, monthly, and half-yearly.
Daily QA : In short limited time before treatment session, we check the reproducibility of the beam.
Monthly QA : We check the characterization of beam as a reference for Daily QA once a month, in detail.
Half-yearly QA : After the scheduled half-yearly shut down of HIMAC, we check condition of the scanningsystem in detail.
Additionally, we newly measure the characterization of beam as a reference for Daily QA and Monthly QA andre-tune the current of magnets from the measured results. In this presentation, we report regular QA as an
operation of scanning irradiation system as NIRS-HIMAC. Improvement in Daily QA activity and relevant
progress will be discussed.

4 YEARS OF OPERATION WITH THE C70 ARRONAX
Freddy Poirier, Arronax
The Cyclone C70 of Arronax is a multi-particles cyclotron based in Nantes, France. Arronax has been running a
regular program for radioisotopes production based on protons at the intensity of the order of 100 µA
simultaneously in two beamlines and at the same time has ensured a wide variety of beams with various
characteristics and particles for an extended R & D program for experimental users. The poster presents thefacility, the machine and operations that are performed at Arronax as well as the difficulties with the runs andsolutions that have been applied.

ARDUINO, OPEN SOURCE PLATFORM USED FOR ENVIRONMENT DATA ACQUISITIONS AT ELETTRA
Andrea Vescovo, ELETTRA
Ambient variables like temperature, humidity, air pressure, vacuum chamber's vibration play an important role
about the quality and beam stability. Using the open source platform Arduino is possible to have an
inexpensive and easy to use single board for all these measurements and to have all the data integrated in thecontrol system.

EleFan SYSTEM AT ELETTRA
Enzo Benfatto, ELETTRA
Automatized remote control system for air cooling prototype of BPM and UDL.

COOLING WATER MANAGEMENT: DISSOLVED OXYGEN AND CLOGGING CORPUSCLE
Hiroki Arai, AEC
HIMAC (The Heavy Ion Medical Accelerator in Chiba) has been supplying medical treatment beam, andresearch experiment beam favorably. There are, however, instances of beam stop, once a while. Diminishedflow rate is one of the most frequent cause of beam stop. For example we use eighty five of Quadrupole
Magnets at HEBT(High Energy Beam Transport) line, and mean value of decreasing amount per week is about
0.3~0.5ℓ/min, or near 10%, when we adjust the cooling water flow during scheduled maintenance time (bi- or
tri-weekly). It is assumed that the cause of diminishing flow rate is a clogged copper oxide. Cooling water flow
increases by removing copper oxide, however we need to prevent the generating of a copper oxide in order tosolve the problem from its root cause. We have been measuring the amount of dissolved oxygen since
March 2014. We found that it is fluctuating from 200 to 1000 ppb. In this presentation, we report ourexperience on the correlation between diminishing flow rate and amount of dissolved oxygen of low
conductivity water in magnet-cooling system. In addition, we introduce other measures in order to prevent
diminishing flow rate.

AUTOMATIC EMITTANCE MEASUREMENT IN THE CERN 1.4 GeV BOOSTER
Jean-Francois Comblin, CERN
To deliver high brightness beams to the LHC, the injectors are running at their stability limit and have to beconstantly tuned to avoid beam degradation. A quality monitoring has been put in place and requires repeatedmeasurements of intensity, transverse and longitudinal emittances. For the Booster, which has 4 rings, thisrepresents a supplementary work load of 1 hour every shift. To minimize the impact for the other facilities
and users, an application has been developed to ease this task: the measurements are done automatically,
while the operator keeps the responsibility of logging the final quality results.

THE RECONSTRUCTION OF THE FERMILAB ACCELERATOR MAIN CONTROL ROOM
Stanley Johnson, FNALThe Fermilab Accelerator Main Control Room has existed in the same location and mostly the same
configuration since the beginning of the laboratory. During a recent long accelerator shutdown, the room wasmostly gutted and rebuilt. This poster will present a brief history of the control room, and look at the planningthat went into rebuilding the room. The final section will look at the new control room and present somelessons learned from the experience.

REMOTE OPERATION AT SNS: TOOLS FOR THE MODERN INTERCONNECTED WORLD
Geoffrey Milanovich, ORNL
The days of being forced to sit in a control room to monitor accelerators are over. There are several tools in use
at SNS that provide remote monitoring of systems. We will demonstrate webpage-based displays, remote EPICS
access, and CSS's WebOPI and EDM2BOY, which makes possible remote operation of an entire accelerator froma cell phone.

CUSTOMER SATISFACTION IN RI PRODUCTION -PRESENT AND FUTURESatoru Hojo, NIRSA NIRS-930 cyclotron has been used for the various purposes since the first beam in 1973. Among others, Radio
Isotope (RI) production has been one of the most important purposes at the NIRS-930. It is necessary to fulfill
the demands from the users of a higher intensity beam such as protons and helium with various energies for RI
production. In order to respond to such demands from users, a future conceptual upgrading plan oriented forhigher intensity beams and stable operation is now under development based on our operation experiences
and hopefully also on the ones at other world front-running facilities.

OPERATION OF NIRS CYCLOTRONS
Yuichi Takahashi, AEC
The cyclotron facility at National Institute of Radiological Science (NIRS) consists of a NIRS-930 cyclotron(Thomson-CSF AVF-930, Kb=110 MeV and Kf=90 MeV) and a small cyclotron HM-18 (Sumitomo- HeavyIndustry HM-18). The HM-18 has been used for production of short-lived radio-pharmaceuticals for PET.
The NIRS-930 has been used for various purposes spreading over from basic sciences to such applications as RI
production and beam irradiation. The control system of axial injection beam line was updated to the systemusing PLC. The beam monitors such as higher intensity viewer and phase probe were installed for operation.
The operational status of the cyclotron facility is to be presented.

COMMISSIONING THE NSLS-II WITH CS-STUDIO
Tasha Summers, BNL
The NSLS-II restarted commissioning in November 2013. By July 2014 the initial goal of storing 50 mA in thestorage ring had been achieved. The primary tool at NSLS-II for interacting with the EPICS control system isControl System Studio (or CS-Studio). CS-Studio is an integrated set of tools which combines operator interfaces(runtime and development), data trending and archive viewing, alarm handling and logbook services. The
operations experience using CS- Studio during commissioning will be presented.

OPERATORS INVOLVED IN MAINTENANCE WORK ON THE ACCELERATORS
Gilles Garnodon, ESRF
Experienced accelerator Operators have a global working knowledge of the machines. During shutdown
periods, Operators are encouraged to utilise and share this knowledge by assisting in maintenance activities
relating to their experience and interests. In this way, they integrate and create links with other groups. Thisvalorises Operator skills and provides variation in their role. We present a poster of ESRF Operators
participating in maintenance tasks around the machine.

THE IMPORTANCE OF COMMUNICATION ABOUT THE ACCELERATORS BY THE OPERATION GROUP
Philippe Roussely, ESRF
Activities and developments on the accelerators are often carried out by small, highly specialised groups. Oneof the principal roles of the ESRF Operation Group is to communicate these activities to the other groups in the
Accelerator and Source Division, both to promote the high-quality work carried out by each group and tocreate a global, cohesive view of the progress of the ASD. This is often done by means of a poster and we
present an example of a typical Run poster, describing the main events, machine parameters and activities
carried out during six weeks of operation.

NEW PARTICLE ACCELERATOR RELIABILITY WEBSITE
Philippe Roussely, ESRF
Following a request from the Accelerator Reliability Workshop in Vancouver in January 2009 for a collaborative
website to enable information exchange and failure trouble-shooting within the accelerator community, theParticle Accelerator Reliability website has been created! We present a poster outlining the main features andthe information available on this site and encourage colleagues to utilise it.

RADIOACTIVE MATERIAL LEAK AT THE HADRON EXPERIMENTAL FACILITY OF J-PARC
Kazuro Furukawa, KEK
In J-PARC, a radioactive material leak accident occurred at the Hadron Experimental Facility (HD facility) on
May 23, 2013. The accident was triggered by a malfunction of the slow extraction system of the Main Ring
synchrotron (MR). A beam of 2x1013 protons was extracted within a very short time of 5 ms and delivered to
the gold target in the HD facility, whereas normally a total of 3x1013 protons were extracted for 2 s. The gold
target was instantaneously heated up to an extraordinarily high temperature due to the short-pulse beam andpartially damaged. As a result, the radioactive material dispersed from the gold target and leaked into theprimary beamline room, because the target container was not hermetically sealed. Since airtightness of the
primary beamline room was not sufficient, the radioactive material leaked into the hadron experimental hall (HDhall) and workers were exposed to radiation. Additionally, due to operation of ventilation fans in the HD
hall, the radioactive material was released into the environment outside of the radiation controlled area of the
HD facility. In this paper, the causes and preventive measures of the accident are presented.

Thursday Oral Presentations
Session: Commissioning & Recommissioning, Checkout before Beam
RECOMMISSIONING OF CPS COMPLEX
Denis Cotte, CERNThe CERN PS Complex just came out of a long shut down period that started in March 2013 and ended June 2014.
During this long shut down the entire accelerator control system was renovated and upgraded. As consequence theuser interfaces were updated and controls tools have been reconfigured. All the machine hardware was recommissioned at the end of the shutdown period, after which many dry runs were performed to test and validate theindividual systems. Prior to the re-commissioning of the accelerators the new and state-of the-art PS Complex access
control and safety system was commissioned and validated. After a cold checkout period during which the machines
are made fully operational without beam, the beam commissioning period took place to setup and provide beams toththe different physics facilities by July 10 . This presentation provides an overview of the major changes together withthe way to make the machines operational again.

RECOMMISSIONING THE FNAL RECYCLER RING FOR PROTON OPERATION
Martin Murphy, FNALIn 2012 the FNAL Main Injector & Recycler Ring were turned off for a 15 month long period of upgrades andrepurposing. The end goal of the project is to increase the beam power delivered to the Neutrino program from 300
KW to 750 KW. We are now over one year removed from the end of that shutdown and the Recycler commissioning is
an ongoing process. The talk will outline what has been accomplished thus far and what obstacles remain. The primarytalking points will be the motivation for the upgrades, an overview of the changes to the machine, the current statusof the recommissioning process, the integration of operators into the process, and how operators are being trained to
run the “new” machine.

COMMISSIONING OF THE 12 GeV CEBAF ACCELERATOR
Brian Freeman, JLAB
The 12 GeV Continuous Electron Beam Facility (CEBAF) was commissioned in two stages. Each stage included extensive
component replacement, rework, and reassembly, followed by a period of commissioning with beam. An inefficientsystem checkout process used during the first commissioning stage contributed directly to a serious magnet fire. As aresult, during the second stage of commissioning, new software tools and processes were put in place to handle
system checks in a more streamlined, comprehensive manner. System owners used a web-based tool to check offcomponents as they were readied for beam, and progress toward completion was tracked in the daily planningmeeting, raising awareness of the requirement for rigorous checkout. Operators and Crew Chiefs used this same tool
to verify the readiness of each machine component before powering-on or operating any device. Commissioning was
successful, and all performance goals were met, without further incident.

“WHAT’S OLD IS NEW AGAIN”: OPERATIONS CONTROL OF RHIC START UP
Travis Shrey, BNL
The RHIC accelerator complex is in a constant state of evolution from run to run. While individual systems may be
modified or added and need to be commissioned, the process of getting the machines ready for Physics production
remains very much the same. The last two runs have seen management of the Start Up period move from control byan accelerator physicist (Run Coordinator) to the Operations group. By reducing the load of scheduling and decision
making from a single person (with usually very limited Operations experience) to a group of people the setup period
has become shorter even as the complexity of the machine has increased. This talk will discuss the mechanisms andcommunications used by Operations during the start-up period.

USING CHECKLISTS AS AN OPERATIONAL TOOL IN ACCELERATOR OPERATIONS
Vince Kempson, DIAMOND
Having presented general benefits of checklists at ARW Melbourne ­ now, a year onwards, it’s time to show checklists
in actual use for important functional steps in accelerator operation: 'Start­up of multiple accelerators , 'shut downs'
each of which we do 5 times a year, machine days (28­30 times a year) and some specific short checklists forreinstatement of beam if it lost are all important areas using dedicated checklists. Development of the checklists andconsolidation of them in a common database structure increases the flexibility available and the ease of creating newones or variants of existing ones. The database has permitted more flexible tools to be used with the checklists toallow work to take place outside the control room avoiding handwritten sheets and tedious manual transfer back into
the diamond elog system.

“NEW AND IMPROVED”: THE JLab (STATE-OF-THE-ART) HCO SYSTEM
Kenneth Baggett, JLab
Determining machine readiness is crucial to ensure safe accelerator operations at machine start-up. Based on lessons
learned at JLab (and other accelerators) a new process and software tool has been developed to allow operations tobetter understand system readiness with respect to accelerator components, checkout requirements and work
interactions. The strength of the new system is its ability to clearly identify the state of all accelerator components
while providing accountability of process. This is accomplished by improving communication between operations,
technicians, system owners, and group leaders, requiring group leader and technician signoff of HCO elements, andsupporting coordination by defining prerequisite tasks. A web based interface provides real-time work completion
status, by group, on accelerator components. Details of how the process was developed, including group feedback
integration, and how it was accepted and utilized during the JLab 12GeV re-commissioning effort and facilitate thepeer-review Accelerator Readiness Review process will be presented.

PREPARATION PHASE OF THE FAIR PROJECTUwe Scheeler, GSI
FAIR will be an unique international accelerator facility for research with heavy ions and antiprotons, hosted by GSI.
The new facility will provide higher energies and higher intensities compared to the present GSI accelerators. The
Commissioning will start in 2017 and operation of the first module is foreseen in 2019. This talk describes the changes
in GSI operation regime and the involved operation group during the project.
Main topics are:

•
•
•
•

Establishing long shutdowns for upgrade and maintenance programs of the present GSI accelerators
Redirection of the operators to new working tasks
extensive accelerator development program in 2014
Coordination of the construction of the new Main Control Room
Training of personnel for the operation of the new machines

INITIAL OPERATION PLANS FOR THE ESS LINAC
Marc Muñoz, ESS
The European Spallation Source (ESS) is planned to be the world-leading source of slow neutrons for neutron
scattering experiments. The facility will aim at a two orders of magnitude performance improvement compared topresent facilities in Europe and consists of a 5 MW, 2 GeV proton Linac for long (ms) pulses, a Target for neutron
production and 22 Instruments for experiments. ESS will be built in the period 2014-2019, with commissioning of the
Linac during 2019, the first neutrons at the end of that year, and expecting to provide 1 MW of power for neutron
production at the end of 2021, with only a part of the superconducting Linac installed. After installation of theremaining part of the Linac, the power would ramp up during the initial operation, reaching 5 MW by 2025. Steadystate operation of ESS will start in 2026, with routine operations and commissioning of initial suite of 7 instruments, toreach the baseline suite of 22 neutron instruments in 2028. This paper presents the plans being developed at ESS for
Linac beam commissioning in order to provide a successful transition from construction to steady state operations,
including details on availability and reliability.

Friday Oral Presentations
Session: Incidents and Lessons Learned
DISSOLVED GAS-IN-OIL ANALYSIS FOR PREVENTATIVE MAINTENANCE OF THE LANSCE HIGH VOLTAGE
SYSTEMS
Karen Young, LANL
The LANSCE linac RF system consists of four 201.25 MHz RF stations that supply RF power to the drift tube linac (DTL),
and forty-four 805 MHz RF stations, that supply RF power to the coupled-cavity linac(CCL). There are four large highvoltage power supplies for the DTL RF systems and seven high voltage power supplies provide the power for the 805
MHz stations. All power supplies consist of a transformer/rectifier, Inductrol Voltage Regulator (IVR) and a capacitor
bank with crowbar protection. After 44 years of operation, some components are approaching the end of life. An
analysis of the oil in the high voltage power supply units was done to assess their health and to determine if units
require maintenance or repair. Since 1998, the oil in each unit has been sampled and tested annually, andreprocessed when required. Gas-in-oil data for these units from 1998 to present was analyzed. The levels of each gas
component, trends in the data and the significance of the each dissolved gas are discussed. Several units have been
re-built. Case studies are presented that correlate the dissolved gas analysis with the failures found.

TROUBLE-SHOOTING IN INITIAL OPERATION OF THE KOMAC 100-MeV PROTON LINAC
Dae-Il Kim, KAERIThe 100-MeV proton linac of the Korea Multi-purpose Accelerator Complex (KOMAC) started to provide a proton
beam to users on July 2013. The KOMAC facility has a 100-MeV proton linac, five beam lines for
20-MeV beam utilization, and another five beam lines for 100-MeV beam utilization. During the linac operation, thedowntime occurred by some troubles related with utilities providing cooling water and electricity, high voltage
modulators for klystrons, and Interlock systems of the MPS (Machine Protection System) and PPS (Personal Protection
System). In 2013 operation, the availability was 82% and the downtime was 94.7 hours. This paper summarizes
troubles in initial operation of the KOMAC facility and presents a preparation to reduce the downtime.

CATASTROPHIC EQUIPMENT FAILURE DURING AN EXTENDED OUTAGE
Thomas Spickermann, LANL
During the most recent extended maintenance outage of the LANSCE accelerator complex at Los Alamos
National Laboratory, a 30-degree bending magnet used to send 800 MeV protons to the WNR facility failed
catastrophically. During shutdown for the maintenance period the magnet was de-energized and the cooling water
system for this magnet turned off. A short circuit in the 24 volt DC magnet control power supply caused failures inseveral control circuits for the magnet, including the module that controlled the magnet power supply. Contacts formagnet interlocks were bypassed by the control circuit failure and the magnet power supply automaticallyramped up to the operational setpoint of about 1800 amps. As a result, the magnet coils overheated and weredamaged beyond repair. A sprinkler right above the magnet was set off and caused a flood that spread soot frommelting plastic over a large area. I will present the course of events as established by two investigation teams, aswell as Lessons Learned regarding shutdown procedures, incident response during outages when the control room is
not staffed, beam tunnel access by incident responders and tracking of legacy inventory.
