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.
