May 12, 2004 TJR5 Conditions of this Study The following are configured as in the TRD (March 28): –The beamline (MAR04 design) –Upstream PiD counters (except as noted) –Downstream PiD counters (including iron shield) These have older configurations: –Magnetic cooling channel, absorbers, and RF are as in the MICE proposal –No vacuum windows; experimental hall is filled with vacuum –Tracker1 and Tracker2 are modeled as virtualdetector-s, vacuum –Absorbers have the bellows windows, both LH 2 and safety Absorbers are empty, RF is off A fixed set of 1M target pi+ is used for every run
