2.4.2 Details of the measurement plan: 2-3 days ofphysical setup in the test beam. 3-4 days of setup and debugging of readout of EMCal and associated beam trigger counters. Then 1) 1-2 days for gain-matching scan with -10 GeVIe electrons through all 64 towers (-1000 e /tower). 2) 1 day for Momentum scan with electrons to investigate linearity and energy and position resolution. 3) 3 days to repeat 1-2) with alternative electronics shaping time. 3) 2 days for detailed position and angle of incidence scan with -10 GeVic electrons to investigate uniformity of response. 4) 3 days for high statistics momentum/position/angle scans with e/pi/p to investigate particle identification by shower shape. 5) 1 day with thick C target in beam just upstream of the EMCal as neutral pion production source via charge exchange reaction to study energy-position resolution via neutral pion invariant mass reconstruction. III. RESPONSIBILITIES BY INSTITUTION - NON 3.1 The EMCal modules and all of its associated readout electronics will be brought by the ALICE EMCal group. 3.2 The array of EMCal prototype modules will be assembled and disassembled on the moveable platform by members of the EMCal group. 3.3 The DAQ computer will be provided by the EMCal group

4.1.7 The integrated effect of running this and other SY120 beams will not reduce the antiproton stacking rate or protons on target for the neutrino program by more than 7 --~~..- -.... ---------~ 5% globally, with the details of scheduling to be worked out between the - experimenters and the Office of Program Planning. 4.2 Particle Physics Division 4.2.1 The test-beam efforts in this MOD will make use of the Meson Test Beam Facility. Requirements for the beam and user facilities are given in Section 2. The Particle Physics Division will be responsible for coordinating overall activities in the MTest beam-line, including use of the user beam-line controls, readout of the beam­ line detectors, and MTest gateway computer. 4.2.2 Maintenance of detector elements in the beamline used to trigger on beam (scintillators, Cerenkov counters, MWPC, etc.) 4.2.3 A horizontal moveable platform with remote control and readout will be provided for mounting the EMCal in the test beam. An engineering assessment of this platform will be done by the PPD. (0.5 person-weeks) 4.2.1 Initial assistance with operation and readout of all beam trigger counters will be provided to the ALICE EMCal group. (0.5 person-weeks) 4.3 Computing Division 4.3.1 The ALICE EMCal group will supply all needed computer equipment. 4.3.2 FNAL will provide Ethernet access in the counting house with access to a printer. 4.4 ES&H Section
