The position of a removable collimator in the beamline has been adjusted
for centering the beam on target location. All the signal cables,
electronics and data acquisition system were checked out during the
test measurements. For multi-crate readout of ∼ 120 parameters,
the total dead time including signal processing and readout time per
event was measured to be 75 μs. Typical coincidence count rates
were ∼ 12 kcs γ-γ doubles and 3-4 kcs γ-γ-γ
triples for a total singles γ rate of 60-80 kcs.
