Beam?	Yes
Additional Personnel

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:¶

• Post Daily Meeting
  • Shifter controlled entry training prior to shift
  • Henry to do a quad soak test to verify upper limit to quad currents.
• 8:45pm
  • Shifters and BLOC arrive to complete Hall preparation (i.e. target prep)
• 10pm
  • Complete diffuser studies continuing from where they were left off on Monday.
  • When complete, take 1/3 of shift with the 190 MeV pion beam (settings below)
  • When complete, take 1/3 of shift with the 300 MeV pion reference beam (i.e. in run control) if not contra-indicated.
  • When complete, take 1/3 of shift with the 290 MeV pion beam (settings below)

• Check that POMPOMs read magnet polarity correctly for input to CDB
• Photograph/Screenshot Run Summary at end of run for comparison to CDB (see screenshot attached to https://micewww.pp.rl.ac.uk/elog/MICE+Log/3223)
• Write more verbose eLogs, describe the problem, its symptoms and solution (if known).

Data Requested¶

• Pion reference beam for diffuser studies.
• 1/3 remainder of shift with 190 MeV pion beam, 1/3 shift on the 290 MeV pion beam, and 1/3 with the nominal beam.

Beamline Configuration¶

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