Shift Duties

  • Take Production data
  • Log all issues, alarms and questions.
  • Perform shift checklist.
  • Log target status twice per shift.

prescaleR PS1=PS2=PS3=1, && PS8=100 (all others zero)

Compton runs

Stop/Start a Compton run every 2 hours - The Compton DAQ is running on the COMPTON computer located in the back room in the Hall A counting house (the room with food)
