a) Runs 43299-43305 . The HV for the some HMS
scintillators was changed (
see
logbook
entry 46239 for list) during run 43299. During run
43301-2 more HV channels were changed (see
logbook
entry 46249) ). This was done to because there was not an equal
number of hits for the opposite ends of the scintillator for some
paddles ( see
logbook
entry 46242 ). The HV were set back to the original values during
run 43305 ( see
logbook
entry 46263). All runs except 43300 are about 5% high compare to
the average normalized yield which indicates that the scintillator
trigger efficiency did improve for these runs.
b) Run 43611.
c) Run 44030.
