Hello, All:
Much good data was taken this shift. For all of the pertinent runs, the
elastic_tof_wire.settings trigger was used; this is (front 8)and(back 8).
The following runs have data in them which have a number of hits per
event distribution peaked around 30-40 hits:
Run Number of Built Events
2064 55000
2068 29000
2069 80000
Using nsed, it looked like all three runs have about 1 event out of every
25 originating in the target (the rest are downstream or else just noise).
In addition, Run 2065 is a run done with no target. With no target, the
built data rate is about 12Hz at 50mA beam current and drops linearly to
2Hz at 10mA. Knowing this, I tried to keep the built data rate around
15-25Hz.
