> **1. INTRODUCTION**
>
> This Memorandum of Understanding applies to the use of the FNAL test
> beam to study the performance of monolithic pixel sensors developed at
> LBNL, Berkeley as part of an R&D program to design and build sensors
> matching the specs of the ILC Vertex Tracker. This activity is carried
> out with funding from a Laboratory Directed R&D (LDRD) grant (P.I.
> Marco Battaglia) in collaboration with INFN Padova, Italy. The tests
> will be carried out as as a collaborative effort of UC Berkeley, LBNL,
> INFN Padova and Purdue University.
>
> The sensors which will be characterized on the Fermilab beamline are
> two CMOS pixel sensors, one with 3T pixels of different sizes and a
> second-generation device which includes in-pixel CDS and fast,
> column-parallel readout. The third sensor is a pixel device, which is
> currently being fabricated in SOI technology, featuring sectors with
> analog and digital pixels. The detectors under test (DUT) will be
> mounted at the end of a beam telescope consisting of three or four
> planes of thinned CMOS pixel sensors, each featuring 1 M pixels.
>
> The purpose of the beam test is first to determine the response of the
> DUTs with high energy particles in terms of S/N, single point
> resolution, two-track separation and detection efficiency for particle
> tracks both at normal incidence and inclined. Then the experimenters
> intend to operate the beam telescope at various levels of particle
> densities to study tracking with four layers of thinned CMOS pixel
> sensors in a realistic environment, matching the track density values
> expected at the ILC in the core of hadronic jets. Finally, the
> experimenters plan to take data with 120 GeV protons on a thin target
> and an interaction trigger, to study vertex reconstruction
> capabilities. These data will be used both to guide the R&D process
> and to validate the event simulation and reconstruction of benchmark
> physics reactions at the ILC.
>
> The memorandum is intended solely for the purpose of providing a work
> allocation for Fermi National Accelerator Laboratory and the
> participating universities and institutions. It reflects an
> arrangement that is currently satisfactory to the parties involved. It
> is recognized, however, that changing circumstances of the evolving
> research program may necessitate revisions. The parties agree to
> negotiate amendments to this memorandum to reflect such revisions.

3\. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS

1.  3.1 LOCATION

    1.  The experimenters plan on using the beam MT6-2b area.

    2.  The experimenters shall mount the experimental setup on an
        optical rail, which will offer the possibility of alignment in
        height. The optical rail should rest on a flat surface, possibly
        an optical table.

    3.  The experimenters shall need some lab space for pre-testing of
        the detectors and possible repairs. The experimenters estimate
        to need two 30x72 desks in a low dust environment (but not
        requiring clean room specs), equipped with ESD-safe surfaces and
        grounding. The experimenters shall also need some office space
        with two desks and ethernet connections.

    4.  The experimenters shall bring all the computers needed for DAQ
        and data analysis and ethernet disks for data storage. The
        experimenters would like to have the possibility to back-up
        approximately 250Gb of data on a centrally managed disk server
        until the data has been transferred to the LBNL cluster.

> 3.2 BEAM

1.  Type of Beam Needed: 120 GeV proton beam and 16 GeV pion beam

> Intensity Needed: 0-100k particles/ (4s spill)
>
> Beam Size Needed: \~ 3 cm**^2^**
>
> The Experimenters shall need the beamline clear of significant
> material upstream of the apparatus during data taking, but can
> tolerate material in front during setup and tuning. The apparatus can
> be removed from the beamline if needed, but requires accesss.
>
> 3.3 EXPERIMENTAL CONDITIONS
>
> The telescope and DUT are installed in an optical box, equipped with
> ventilation and all connections for supplying voltages and trigger
> signals and computer connections for data transfer. The DUT is
> installed on a pair of computer controlled XY stages for relative
> alignment wrt the beam telescope and scanning different sectors. For a
> trigger, the experimenters shall need a NIM/TTL signal from the beam
> line hodoscope and a begin-of-spill which precedes the spill by at
> least 100ms. The experimenters would benefit by being able to record
> the Cherenkov response on beam composition and have information on
> beam energy and energy spread. For the run with a target the
> experimenters shall add a detector plane in front of the target and
> provide an interaction trigger signal using a pair of scintillators
> installed in the telescope box.

4.  ELECTRONICS:

> The system is readout through a custom DAQ system. The readout boards
> will be located in the same box housing the telescope and DUT and will
> communicate with the DAQ PC via a NI PCI interface. The board firmware
> is uploaded through a USB-2 link. The board takes a TTL signal input
> for the trigger and the experimenters shall route about ten digital
> signals out to the control room for diagnostics during tuning and data
> taking. All detectors are operated at low voltage (6 V), low currents
> (\< 2 A) with the only exceptions of the SOI detector which will be
> biased to 50-60 V. HV connectors will be installed on the telescope
> optical enclosure and no exposed HV parts will be present.
>
> 3.5 SCHEDULE:
>
> The experimenters are currently envisaging two possible run periods,
> depending on the Fermilab accelerator schedule. The first is from June
> 25 and the second from August 12.
>
> Day 1: Installation in Lab, detector tests, cable connection, PC
> connection and tests, deploy
>
> setup on beamline, basic test with random trigger.
>
> Day 2: Safety inspections, alignment and setup with beam.
>
> Day 3: Run beam Telescope with 120 GeV protons, track alignment
>
> Day 4: Run beam Telescope with 16 GeV pions, change intensity,
> tracking tests.
>
> Day 5: Install LDRD-1 detector, run with 120 GeV protons
>
> Day 6: LDRD-1 detector, sector scan, inclined tracks
>
> Day 7: Install LDRD-2 detector, run with 120 GeV protons
>
> Day 8: LDRD-2 detector run, inclined tracks

7.  SPECIAL CONSIDERATIONS

7.1 The responsibilities of the PI of the LBNL group and the procedures
to be followed by experimenters are found in the Fermilab publication
\"Procedures for Experimenters\":
(<http://www.fnal.gov/directorate/documents/index.html>). The Physicist
in charge agrees to those responsibilities and to follow the described
procedures.

7.2 To carry out the experiment a number of Environmental, Safety and
Health (ES&H) reviews are necessary. This includes creating an
Operational Readiness Clearance document in conjunction with the
standing Particle Physics Division committee. The PI of the LBNL group
will follow those procedures in a timely manner, as well as any other
requirements put forth by the division's safety officer.

7.3 The PI of the LBNL group will ensure that at least one person is
present at the Meson Test Beam Facility whenever beam is delivered and
that this person is knowledgeable about the experiment's hazards.

7.4 All regulations concerning radioactive sources will be followed. No
radioactive sources will be carried onto the site or moved without the
approval of the Fermilab ES&H section.

7.5 All items in the Fermilab Policy on Computing will be followed by
the experimenters. (<http://computing.fnal.gov/cd/policy/cpolicy.pdf>).

7.6 The PI of the LBNL group will undertake to ensure that no PREP or
computing equipment be transferred from the experiment to another use
except with the approval of and through the mechanism provided by the
Computing Division management. They also undertake to ensure that no
modifications of PREP equipment take place without the knowledge and
consent of the Computing Division management.

7.7 The LBNL group will be responsible for maintaining and repairing
both the electronics and the computing hardware supplied by them for the
experiment. Any items for which the experiment requests that Fermilab
performs maintenance and repair should appear explicitly in this
agreement.

7.8 At the completion of the experiment:

> 7.8.1 The PI of the LBNL group is responsible for the return of all
> PREP equipment, computing equipment and non-PREP data acquisition
