Positron runs
setup trigger scintillators before MMS target
take 1M e+ and 1M e-
Proton runs
2. study pedestal drift vs rate:
p at 10 GeV setting LAT threshold to 5 DAC - repeat
Special runs
CAL FHE study : check DAV-MeV conversion, efficiency
+++ BT-17 to BT-21 configurations
+ electrons, 0 degree, 5GeV/c, tower 3,
FHE=500MeV-750MeV-1000MeV-1500MeV-2000MeV
+ electrons, 45 degree, 5GeV/c, tower 3,
FHE=500MeV-750MeV-1000MeV-1500MeV-2000MeV
Pile-up verification runs
Setup a random trigger and take couple of quick runs (20k evts) in random trigger to directly measure pile-up events;
