INTRODUCTION

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and experimenters from Argonne National
Laboratory (HEP) and Iowa University who have committed to participate
in beam tests to be carried out during the 2005-2006 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 set of Resistive Plate Chambers which have been
built at Argonne in the context of developing Particle Flow Algorithm
Calorimetry for the ILC. The purpose of the tests is to confirm the
performance of RPCs with respect to the occupancy and hit rates to be
expected in tests of prototype calorimeter modules in particle beams.
The tests will start in fall 2005 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 Resistive Plate Chambers for hadron calorimetry
initiated at Argonne several years ago. The work has been funded by DOE
through strategic LDRD grants. The detailed goals of this small scale
beam test are listed below. Details concerning the design and properties
of Resistive Plate Chambers, including the various pad readout schemes,
can be found in Appendix I.

**II. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS**

1.  LOCATION

    1.  The experiment is to take place in the MTEST beam line, and the
        MT6enclosure. The experimenters' first choice for location in
        the enclosure is MT6-B3 on the existing motion table, downstream
        of the T950 straw-tube test. Our second choice is in MT6-A2 on
        the upstream half of the CMS table. Our preliminary running for
        debugging could be done downstream of the beam stop in MT6-C if
        there is adequate rate of muons per unit area (see beam request)
        . In addition, the main control room to the west of the MTEST
        line will be used to house electronics .

    2.  We will need one 19 inch rack for electronics in the beam area,
        room for a Camac crate and NIM bin in the control room and space
        for more camac modules in an existing beam signal crate.

    3.  Additional work space will be needed in the control room,
        equivalent to at most two 6'x3' tables. This space will be used
        for computing and general work space.

    4.  We propose to put our tanks of pre-mixed gas near the racks in
        the gas distribution area. The house with the gas bottles could
        be inappropriate because the gas lines cross several feet
        between buildings, and in the winter weather some components of
        our gas mixture could condense.

2.  BEAM

    1.  BEAM TYPES

> The tests will use slow resonantly-extracted, Main Injector proton
> beam focused onto the MTest target. We will need muons, Pion beams and
> probably Electron beams. We list a series of requirements, roughly in
> order of priority and sequence of running:
>
> A\) Muons with no more than 2% electrons, and no more than 10% pions
> for our debugging and efficiency measurements. We will need rates down
> to 10-50 Hz total over a 5 inch square. Presumably this request could
> be obtained by inserting the MT6 secondary beam stop. Setup with our
> first of 3 readout methods could require 3 to 4 weeks, and we would
> want to have priority in utilizing the test beam for one week of this
> time. Setup and debugging of the other readout methods could initially
> be downstream of the final beam stop in MT6C.
>
> B\) Pion beam: First at a low energy such as 4 GeV and a range of
> intensity from roughly 10-50 Hz. Momentum spread should be less than
> +- 20%. Part of this running would be with material in front of the
> RPC to develop hadron showers and part of the running without
> material. Total time would be one week with the first readout system,
> with control over the beam for roughly half this time. Additionally, a
> few days for each of the other two readout methods is required at a
> later time. Cherenkov signals are needed to tag electrons.
>
> C\) Pions at 10 GeV with a range of intensity from roughly 10HZ total
> over 5 inch square to a few hundred Hz over an area of a square inch.
> Momentum spread should be less than +- 20%. Running will be with
> material in front of an RPC for hadronic showers. Two days for each of
> three setups.
>
> D\) Pions at 30 GeV with a range of intensity from roughly 10HZ total
> over 5 inch square to a few hundred Hz over an area of a square inch.
> Momentum spread should be less than +- 20%. We will run with material
> in front of an RPC for hadronic showers. Two days for each of three
> setups. E) Electrons of 8 GeV, with beam intensity from 10 to 100 /
> cm\^2 / spill. Tagging of electrons will be done by the two beamline
> Cherenkov counters. Running with showering material (lead and
> aluminum) and with no showering material in the beam. At least two
> days total will be required for this run, but distributed over the
> running times for all three electronics systems.

2.  

3.  BEAM SHARING: Most likely we could run parasitically downstream of
    some other test during most of our setup and debugging. Also,
    because of limited manpower we cannot run continuously. We can
    alternate with other users

4.  

5.  RUNNING TIME: Beam time is requested in beam requests A- E above. We
    would be constrained in time by not having a lot of manpower. We
    propose that the setup could be done in steps over a few weeks, and
    the running could be various short runs of hours to a couple of days
    as beam and manpower were available. We request to remain in the
    beam area until March, but with our material moved out of the actual
    beam when necessary for other users.

SETUP

2.3.1 Our setup consists of a stand with one to five RPC's and removable
material to generate hadronic showers as in a calorimeter. The detector
part would be less than 1 cubic foot in the beamline (above some table),
but we need room for iron plates for shower development in front of our
detector. The parts can be carried in by hand. (the total weight might
be a few hundred pounds).

2.3.2 A table in the beamline to support the detector, and the iron
plates for shower development. We request to use the existing motion
table in MT6-B which is at least 7 inches below the beam and also would
allow our showering material to be rolled to the side of the beam
easily. We expect to have less than 600 pounds of material in less than
1 meter length.

2.3.3 Electric power for electronics both in the beam area and in the
counting house.

2.3.4 Ethernet connection for data transmission offsite from a computer
which will use ftp to transfer image files to a processor in VME. If
there is a firewall issue, the data can be transferred in sequential
transfers between networks.

2.3.5 We require crate with either , a network connection, ing RPC
readout software for a at Fermilab

2.3.6 Access to the beam area periodically for installation and cabling
and installing gas lines. 2.3.7 will supply at least one DAQ computer.

2.3.8 We need discussions on whether to use the MTBF how to combine data
from 3 different readout systems.
