Shift Monitoring¶

Shifters should keep a careful eye on:

• Water chiller temperature outside the control room (bottom of the red LEDs). If this reaches 25C, immediately power down the magnets and inform the MOM.
• Magnet water temperatures.
  • Log any abnormal changes in the eLog
  • If yellow temperature alarm sounds, immediately power down the magnets and inform the MOM.
• Magnet water flows.
  • Log any abnormal changes in the eLog
  • If yellow alarm sounds, immediately power down the magnets and inform the MOM.
• EMR stopping the DAQ arming
  • Power cycle the VME crate by following the instructions here

Shift plan:¶

• 8:45pm
  • Shifters + BLOC arrive
  • Hall and beam line to be closed and prepared for beam
• 10pm
  • Try 500 spills of a (10, 240) muon beam -- settings in Run Control, make sure no diffuser is in the beam
  • Monitor magnet and chiller temperatures, ramp down on ANY YELLOW ALARM or if chiller approaches 25C
  • If (and only if) temperatures are OK, continue for 100k triggers at TOF2
  • Else: take 100k triggers at TOF2 of the (3, 200) muon beam as done last night.
  • Then: TOF calibration for remainder of shift.

Data Requested¶

• (10, 240) or (3, 200) muon beam depending on magnet temperature study -- settings in Run Control, no diffuser
  • Trigger from TOF1
  • 100k triggers at TOF2
• TOF calibration until end of shift -- settings in Run Control

Beamline Configuration¶

• We expect to run with 2V beamloss and the beam bump active.
• DS is off
• Beam settings via Run Control

TOF Calibration run¶

These settings are now in Run Control.
