Detector checkout and calibrations

Additional instructions:

• We run both the COIN and separate DAQs during this phase!
• Inelastic measurement:
  • Take 5min of MODE 10 data before starting the the inelastic measurement, then switch back to MODE 9.
• Coinc elastic:
  • Take 5min of MODE 10 data before starting the the inelastic measurement, then switch back to MODE 9.
  • Take pre-scaled 3/4 singles in both arms, set pre-scalers so the singles rate is <100Hz
  • This run needs a special temporary trigger that will be connected to PS5
  • Make sure sure PS5 = 0

Production

Production phase 1 (Production checkout and 66% of High-E/low-t point)

Additional instructions:

• High-E/low-t:
  • Take 5min of MODE 10 data before starting each polarity, then switch back to MODE 9.
  • Make sure to do at least one dummy run every shift
  • Make sure to do at least one 30min radiator-out run every shift
  • Make sure the production pre-scaler is set to 0
  • Take pre-scaled 3/4 singles in both arms, set pre-scalers so the singles rate is <100Hz

Additional instructions:

• Mid-E/low-t:
  • Take 5min of MODE 10 data before starting each polarity, then switch back to MODE 9.
  • Make sure to do at least one dummy run every shift
  • Make sure to do at least one 30min radiator-out run every shift
