HRS checkout plan after beam is estabilshed on the target with BeO target
HRS angle 15 degrees, momentum P0 = 2.0 GeV/c, Raster size = 3x3 mm, current = 5uA, target = Carbon
Take Left and Right HRS runs in the following order. Always keep deadtime to below 10 %
- 1M events with T1 trigger, prescales values: ps1=non-zero, ps2=0, ps3=0, ps4=0, ps5=0, ps6=0, ps7=0, ps8=0 (adjust ps1 based on scaler rates)
- 1M events with T2 trigger, prescales values: ps1=0, ps2=non-zero, ps3=0, ps4=0, ps5=0, ps6=0, ps7=0, ps8=0
- 1M events with T3 trigger, prescales values: ps1=0, ps2=0, ps3=non-zero, ps4=0, ps5=0, ps6=0, ps7=0, ps8=0
- 1M events with T4 trigger, prescales values: ps1=0, ps2=0, ps3=0, ps4=non-zero, ps5=0, ps6=0, ps7=0, ps8=0
- 1M events with T5 trigger, prescales values: ps1=0, ps2=0, ps3=0, ps4=0, ps5=non-zero, ps6=0, ps7=0, ps8=0
- 1M events with T6 trigger, prescales values: ps1=0, ps2=0, ps3=0, ps4=0, ps5=0, ps6=non-zero, ps7=0, ps8=0
