Before taking Counting Runs:
- Turn ON S0 and S3 (L0.0, L0.1, L0.2, L0.3, L0.4 in both arm's HV GUI)
- For Raster Check in C-Hole
  - Ask low current <2uA such that T1 rate <100kHz
  - Ask for appropriate raster size and position lock as in WHITE BOARD
  - Follow Checking the HV HOW TOs for shift crew if you need to
  - You can start runs once the position and HV read-back are settled
- For Detector alignment Check
  - Ask for low current (0.3uA on Ca-48 target)
  - Ask for appropriate raster size and position lock as in WHITE BOARD
  - make sure the T1 rate is ~200kHz
  - turn ON VDC (L6.0, L6.3 in LHRS and L4.5, L4.7 in RHRS) if the T1 rate is good
  - set Downstream MAIN detectors HV to -1900V (L1.1 in both arms), and turn them ON
  - once the position and HV read-back are settled, take runs
  - follow Taking MAIN detector Counting Run if you need to analyse data
Once you are done with counting Runs:
- Turn OFF S0, S3, Downstream MAIN detectors, and VDCs and set Downstream MAIN detectors HV to 0.0V
- Ask for high current (production) only after turning OFF the detectors mentioned in the previous step
