**introduction**

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and experimenters from University of Chicago,
KEK, Kyoto University, and Osaka University, 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 4x4 array of 16
undoped CsI crystals (aka KTeV CsI crystals). Each of these crystals is
5cm (W) x 5cm (H) x 50cm (L) (27 radiation length). The focus of the
test is to validate a new electronics technique to measure both charge
(ADC) and time (TDC) simultaneously. The raw CsI pulse will be shaped by
a front end 10-pole Gaussian filter, then digitized with 125 MHz FADC
with FPGA/VME readout. From simulations and cosmic ray tests, the timing
resolution is \~ 100 psec, but needs to be validated by high energy
particle beam measurement.

JPARC experiment E14, an approved experiment to measure the rate of K~L~
-\> π^0^ ν ν plans to use the new technique for all its detector
elements including \~3000 channels of KTeV CsI crystals. With the
anticipated time resolution, it is possible to perhaps determine the
momentum of the measured photon. When a photon (\~few tens of MeV to
GeV) strikes the CsI array, few tens of blocks will have deposited
energy. The times of arrival of the blocks, therefore the longitudinal
distances of shower development can be measured with resolution of \~3cm
(corresponding to the 100 psec time resolution). Therefore, the
direction of the photon perhaps can be determined by these time
distributions.

The tests will take place in December 2007. This test is limited by the
number of electronic channels; pending results of this test, larger
array of CsI test may be needed.

**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 one VME crates)

-   Dry nitrogen supply

-   The upstream motion table, which is capable of holding the 200 lb
    detector assembly.

-   Space in the beam line for a 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.

    ```{=html}
    <!-- -->
    ```
    1.  

    2.  BEAM: The tests will use the slow resonantly-extracted, Main
        Injector proton beam focused onto the downstream MTest target.
        The experimenters will need mostly low energy (1-8 GeV) electron
        beam. Low intensity beams (50 -- 1000 Hz onto the 1 x 1 cm^2^
        trigger counters) will be ideal.

    3.  

    4.  2.  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.

        3.  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^.
            Measurements with low momentum electrons (1 -- 8 GeV/c) are
            needed. The experimenters will likely require about 10 days
            of beam time.

    ```{=html}
    <!-- -->
    ```
    2.  SETUP: The experimental setup consists of two parts: a) a
        calorimeter stack (see Figure 1) with the 16 CsI crystals. Each
        crystal is 5cm x 5cm x 50cm. The stack will be placed inside a
        light tight box with dry nitrogen feed. The dimension of the box
        is 75cm x 75cm x 100cm. The total weight of the setup will not
        exceed 200 lbs. The stack is to be located on top of a scanning
        table; and b) a beam telescope consisting of 2 scintillation
        counters, fixed in space and located in 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 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
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 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 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 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 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
