INTRODUCTION

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and experimenters from Argonne National
Laboratory (HEP), Boston University, University of Iowa, and University
of Texas at Arlington who have committed to participate in beam tests to
be carried out during the 2007 MTBF program. The memorandum is intended
solely for the purpose of providing a budget estimate and a work
allocation for Fermilab, the funding agencies and the participating
institutions. It reflects an arrangement that currently is satisfactory
to the parties; however, it is recognized and anticipated that changing
circumstances of the evolving research program will necessitate
revisions. The parties agree to negotiate amendments to this memorandum
which will reflect such required adjustments.

The tests involve a small calorimeter consisting of a stack of steel and
copper plates interleaved with Resistive Plate Chambers (built at
Argonne) and Gas Electron Multiplier chambers (built at UTA). The
chambers are read out with a digital readout system (developed and built
by Argonne, Boston, and Fermilab). The Iowa group contributes the gas
and High Voltage distribution system. The proposed tests are in the
context of developing Particle Flow Algorithm Calorimetry for the ILC.
The purpose of the tests is to establish the viability of the electronic
readout system for calorimeters with fine granularity and to measure the
performance of RPCs/GEMs in hadronic showers. The tests will take place
in June/July 2007 and should be regarded as a precursor to the larger
tests planned by the CALICE collaboration and the American Linear
Collider Calorimetry groups.

The research on RPCs (GEMs) for hadron calorimetry was initiated at
Argonne (UTA) several years ago. The work at Argonne (UTA) has been
funded by DOE through strategic LDRD (LCDRD) grants. The detailed goals
of this small scale beam test are listed below.

II\. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS

1.  LOCATION

    1.  The experiment is to take place in the MTEST beam line, in the
        MT6-2A area.

    2.  The following items will be needed in the beam area:

-   1 19-inch rack for electronics (to house two NIM and a VME crates)

-   Space for a gas distribution rack (to be brought from Argonne )
    close to the test set-up

-   The upstream motion table, which is capable of holding the 500 lb
    detector assembly.

-   Space in the beam line for our beam telescope, to be located in
    front of the motion table.

    1.  Additional work space will be needed in the control room,
        equivalent to at most two 6'x3' tables. This space will be used
        for the data acquisition PC and as general work space.

    2.  The experimenters propose to put a tank of pre-mixed gas near
        the gas distribution rack.

    <!-- -->
    ```
    1.  

    2.  BEAM: The tests will use the slow resonantly-extracted, Main
        Injector proton beam focused onto the MTest target. The
        experimenters will need mostly 120 GeV proton beams. Due to the
        long recharge time of RPCs, low intensity beams (50 -- 1000 Hz
        onto our 1 x 1 cm^2^ trigger counters) are needed. Additionally,
        tests with low momentum pion and electron beams (1 -- 8 GeV/c)
        will be useful.

        2.  

        3.  

        4.  BEAM SHARING: Most likely we the experimenters could run
            parasitically downstream (didn't we talk about getting our
            setup at the most upstream, MT6 section 2A?) of some other
            test during most of ourthe setup and debugging the time if
            other tests they ran require low rates. However, note that
            most of the debugging will have been done at Argonne before
            the equipment will be shipped to FNAL tes and the hadrons
            and electrons got through without too much conversion,
            contamination by muons, etc. BAlso, because of limited
            manpower the experimenterswe cannot run continuously.
            Alternating with other users is possible.

        5.  RUNNING TIME: The experimenters estimate the need for
            several 8 hour periods of running time to explore the phase
            space of experimental conditions (various HV and threshold
            settings) with rates of the order of 100 Hz/cm^2^.
            Additionally, tests with variable beam rates (to measure the
            rate capability of our apparatus) are required. Finally,
            measurements with low momentum pions and electrons (1 -- 8
            GeV/c) are needed. The experimenters will likely require two
            weeks of beam time.

    ```{=html}
    <!-- -->
    ```
    2.  SETUP: The experimental setup consists of two parts: a) a
        calorimeter stack (see Figure 1) with up to 10 RPCs and GEMs
        interleaved with steel and copper plates. The lateral dimensions
        of the absorber plates are approximately 30 x 30 cm^2^. The
        total weight of the setup will not exceed 500 lbs. The stack is
        to be located on top of a scanning table; and b) a beam
        telescope consisting of 5 scintillation counters, fixed in space
        and located in front of the stack.

3.  COMPUTING: The experimenters will supply their own DAQ computer.
    Ethernet connection (with capability of using SSH) will be required
    for data transmission offsite (and downloading of updated versions
    of firmware from outside institutes).

# **VI. SPECIAL CONSIDERATIONS**

6.1 The responsibilities of the spokesman of the DHCAL Detector Research
group and 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.

6.2 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 spokesman of the DHCAL
Detector Research group will follow those procedures in a timely manner,
as well as any other requirements put forth by the division's safety
officer and follow all procedures in the [PPD Operating
Manual.](http://www-ppd.fnal.gov/DivOffice/Operating_Manual/index.htm)

6.3 The spokesman of the DHCAL Detector Research 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.

6.4 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.

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

6.6 The spokesman of the DHCAL Detector Research 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.

6.7 The DHCAL Detector Research 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.

6.8 At the completion of the experiment:

> 6.8.1 The spokesman of the DHCAL Detector Research group is
> responsible for the return of all PREP equipment, computing equipment
> and non-PREP data acquisition electronics. If the return is not
> completed after a period of one year after the end of running the
> spokesman of the group will be required to furnish, in writing, an
> explanation for any non-return.
>
> 6.8.2 The experimenters agree to remove their experimental equipment
> as the Laboratory requests them to. They agree to remove it
> expeditiously and in compliance with all ES&H requirements, including
> those related to transportation. All the expenses and personnel for
> the removal will be borne by the experimenters.
>
> 6.8.3 The experimenters will assist the Fermilab Divisions and
> Sections with the disposition of any articles left in the offices they
> occupied.
