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.
