INTRODUCTION

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and experimenters from Indiana University,
University of Notre Dame, Wayne State University, University of
California at Davis, and Fermilab/ILC, who have committed to participate
in beam tests to be carried out during the 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
may necessitate revisions. The parties agree to negotiate amendments to
this memorandum which will reflect such required adjustments.

The tests are to study the performance of a set of four prototype ILC
muon detector modules. The modules are each 1.25 m x 2.5 m and consist
of 64 strips of scintillator oriented at +/- 45º to the edges of the
module. Thus far the group has tested two of the modules in Lab 6 using
radioactive sources and cosmic rays. The source does not accurately
reproduce the energy deposition of a muon in the scintillator, and the
cosmic ray rates are too low to map the response of the detectors at
sufficient numbers of points on all the strips. Thus the experimenters
need to test in a beam to determine the strip-to-strip variation in
efficiency and the average number of photoelectrons from the modules.
The test data will also provide important information about the
position-dependence of the response along the strips. Two of the modules
have readout at one side of the counter and the other two have
double-sided readout. The tests will provide a quantitative answer to
whether it is necessary to use double-sided readout or not.

The experimenters have reported earlier test results of a smaller
pre-prototype module at the March, 2005 ILCWG meeting at Stanford, and
source and cosmic ray tests of the first two prototype modules at the
August, 2005 ALCPG meeting at Snowmass.

This proposal outlines a plan for test beam time during 2006. The
experimenters plan to initiate testing prior to the March, 2006
accelerator shutdown, and continue the tests after the shutdown.

#  EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS

2.1 LOCATION

2.1.1 The tests are to be performed in the MTEST beam line, in the MT6
enclosure. The experimenters are considering 2 locations in the MTEST
enclosure. One is in the MT6-B1 area,. The second is in the MT6-B4 area,
or downstream of the movable table in MT6-B3. In both of these locations
the shielding wall and the electrical conduits along the wall limit the
movement of the apparatus toward the west, such that approximately 20%
of the detector could not be moved into the beam. To pass the beam
through the remaining parts of the detector requires removing the
detector from its cart and turning it 180º about a vertical axis, and
replacing it on the cart. See Appendix II for a diagram. The
experimenters note that there is more space available in the MT6-B4
area.

2.1.2 Several modifications to the MTEST area are needed to support the
tests. The experimenters may need an additional cable tray or patch
panel to carry the signal cables from the detector to the fast
electronics control area. The experimenters will need some support to
align the apparatus relative to the beam line. In the MT6-B1 location it
would be necessary to move the silicon detector that is just upstream of
the MT6-B2 enclosure to allow room for the apparatus.

2.2 BEAM

2.2.1 BEAM TYPES

The experimenters can operate with a variety of beam types. The main
requirements are rate and spot size. The experimenters need a spot size
that is well contained within one strip. The 45° crossed strips have a
diamond-shaped overlap area that is about 6 cm by 6 cm in size, so a
beam spot of about 1 cm x 1 cm would be very good. The experimenters
first choice for best rate and spot size is the 120 GeV positive beam,
although the experimenters could run with lower energy beams. The
experimenters also intend to test with muons after the efficiency
mapping tests are completed. This would be after the March shutdown.

2.2.2 BEAM INTENSITY

The experimenters prefer running at 120 Gev positive beam, with ≈150 K
particles per pulse. This gives the smallest spot size as well. The
experimenters could also operate at lower beam energies, but the data
collection times would be increased. A detailed estimate of running time
is given in section 2.2.4. As an example, a beam rate of 50 K per pulse
would increase the time for coincidence measurements from 4 minutes per
point to 12 minutes per point, and would not increase the time for ADC
data collection or non-data collection task time. It would increase the
overall time per point by 8 minutes, from about 17 minutes to about 25
minutes.

2.2.3 BEAM CONTROL

The experimenters are requesting control to steer the beam so that the
experimenters are able to move the beam to hit several strips for a
given position of the set of counters. This means that the experimenters
would like to be able to control the elements in M05, including MT5E and
MT5V. This would enable them to reduce the number of accesses required
to reposition the apparatus. A typical run entails a horizontal scan to
take measurements on all 64 strips at a particular vertical position.
Then the set of counters is moved up or down to another vertical
position for the next horizontal scan. The experimenters intend to make
about 8 scans. At each position the fraction of beam counts in
coincidence with the counters is recorded on scalers. In addition the
experimenters will collect pulse information on ADCs to analyze the
charge collected.

2.2.4 BEAM SHARING

Because of limited manpower availability and other commitments the
experimenters would be unable to run continuously. They prefer to
alternate beam time with other users. The amount of material in the beam
would be 4 cm of scintillator for the test counters, 1 cm more for the
beam defining counters, and 2 mm of aluminum for the packaging on the
test counters. If this amount of material is not compatible with other
users, the counters could be moved eastward out of the beam in either
the MT6-B1 or the MT6-B4 location.

2.2.5 RUNNING TIME

Assuming a conservative figure for the particle rate at 120 GeV, 150 K
per spill, two spills would give 300,000 beam particles, for 0.2%
statistics for coincidence measurements. A typical scenario would be to
do a horizontal scan across the counters; then move the counters to a
new vertical position, and do the next horizontal scan, etc. Assuming a
spill every 2 minutes the following more detailed scenario is envisaged:

1.  Two pulses to collect coincidence data (4 minutes)

2.  Unplugging the signal cables from the discriminators and connecting
    them to the ADCs in the control area, or vice versa (2 minutes)

3.  Time to accumulate ADC data: LeCroy 2249 ADCs have a digitization
    time of 60 μsec, which limits the acquisition rate to 17000 per
    pulse. Two pulses are sufficient for a spectrum. (4 minutes). The
    experimenters are looking into the use of LeCroy 4300, 16 channel
    ADCs, which have a shorter digitization time.

4.  Steer beam to hit next strip (5 minutes)

5.  After every 4^th^ strip is hit, move the structure to next position,
    4 strips over. At this time the experimenters would move the signal
    cables at the detector that connect to the panel in the MT6 area.
    (The experimenters do not intend to run cables and provide
    instrumentation for all channels at one time. The experimenters
    estimate that each move will take 10 minutes, so the time per strip
    is 2.5 minutes. (2.5 minutes). Each move requires a 10 minute access
    to the test beam area, approximately once per hour.

The total time per point in a horizontal scan is 17.5 minutes, rounded
to 20 minutes. For each scan there are 64 points, for a total of 21
hours per scan.

At the completion of each horizontal scan the apparatus must be moved
vertically for the next horizontal scan. This should require an access
of about 30 minutes. The experimenters anticipate about 8 vertical
re-positions, or 4 hours. At present the experimenters are trying to
simplify the structure to hold the detector by limiting the height of
the structure. The experimenters are planning to have the highest
position with the beam at the center vertically, and lower the detector
to pass the beam through its upper half. Then the experimenters will
remove the detector and rotate it 180º about a horizontal axis, and
remount it do the other of the scans on the other half in the same
manner. See section 2.3 below. The experimenters anticipate doing the
rotation once or twice, about 2 hours per rotation.

In total the data taking time for 8 full horizontal scans is 168 hours
plus 8 hours for vertical re-positioning, and 2 hours for turning the
detector around to expose the inaccessible end portions, or 180 hours.
This would take about 3 weeks of running time at about 60 hours per week
to complete the tests. Time permitting the experimenters would turn the
detector around to expose the portion that is unable to move westward
into the beam because of the limited space between the beam line and the
west shielding wall. This would only be done when the beam is off for
periods of 4 hours or more.

As discussed above, the experimenters are willing to split up the
testing into several separate week long periods.

2.3 SETUP

The apparatus consists of 4 scintillation counters, each 1.25 m x 2.5 m,
and a movable stand that holds the set of 4 counters. The 4 counters are
mounted in a row along the beam, aligned relative to each other so that
their active areas line up, approximately 10 cm apart. For a fixed beam
position, the motion of the set would be in increments of about 6 cm to
center the beam on individual strips, which are 4.1 cm wide at 45º. If
the experimenters have control of the beam steering the experimenters
would be able to hit 3-4 counters at any position. The experimenters
also need 4 small scintillation counters in fixed positions across the
beam to define the 4 beam positions. The set of 4 counters will be
mounted as a unit, and the unit will move horizontally on a cart
transverse to the beam. For the pre-shutdown period the counter unit
will be mounted on a simple cart, and instead of moving the counter unit
vertically upward to position the beam on the lower half of the counters
the experimenters plan to move the unit downward to expose its upper
half to the beam, then rotate the counter around so the lower half is
above the beam line. Then the experimenters lower the unit by increments
to do the remaining horizontal scans. The experimenters require the use
of an A-frame to install the unit in the cart and to lift out the unit
to turn the unit over. The experimenters are considering building
rotation capability on the cart to allow rotation.

2.4 ELECTRONICS NEEDS

The number of channels in the system is the following: each of the
single-ended readout modules has 64 channels and each of the
double-ended readout modules has 128 channels, for a total of 384
channels. For a fully instrumented system, each channel would have a
discriminator, and an ADC. This would also require hundreds of cables
between the detector and the electronics. However, a partially
instrumented system would be acceptable for tests in which the beam is
passing through a small region of the detector at any particular time.
In the minimal configuration the beam passes through a single counter in
each of the planes, or 6 channels. This is not optimal because the
cables need reconnection each time the beam or setup is moved, and there
is no information from adjacent strips for each trigger. A reasonable
compromise is to instrument a block of 8 adjacent strips at a time, or
48 channels. The signal cables could be accommodated in the 50-channel
patch panel in MT6-B3, for example. For this the experimenters would
need 48 channels of ADCs and 48 channels of discriminators, as well as
supportive coincidence logic and scalers. There are 4 functional areas
that require electronics:

1.  The experimenters need to form a coincidence between the beam
    signal (B) and each of the 4 beam steering target counters (T~i~).
    This requires fanning out the beam signal, coincidence units, and
    scalers to count the coincidences.

2.  The targeted beam signal (B. T~i~) for the selected target counter
    is then fanned out and put in coincidence with each of the 8 strip
    signals that are instrumented per module (S~jk~), where i=1,8 strips
    and j=1,6 where j is the PMT number. (Recall that the double-sided
    readout units have 2 PMTs, one for each side.) This requires a total
    of 48 coincidence channels for the 4 modules, and 48 scaler
    channels. The experimenters also anticipate the need for amplifiers
    to boost the signals from the PMTs, and discriminators are needed
    for each of the signals.

3.  The third logic area is the ADC function. Each of the 48 signals is
    connected to an ADC channel with a delay to arrive at the correct
    time with respect to the trigger gate.

4.  In addition the experimenters need miscellaneous units such as gate
    generators to gate the scalers.

A list of electronic units required, and those the experimenters already
have, is in Appendix III.

2.5 SCHEDULE

The experimenters propose to begin installing the equipment and setting
up the electronics in late January, begin data-taking in mid-February,
and to take data for several weeks before the March shutdown. The second
phase of running is after the March shutdown. If access to the test area
is not available to install the equipment prior to the shutdown the
experimenters would set up the equipment during the March shutdown and
run the tests after the shutdown.
