Current Status

  • Q2=5.5, x=0.5 (pi-) kinematic setting in progress (lowest z setting)

Current Run Plan

  • Finish Q2=5.5, x=0.5 (pi-) kinematics.
  • Continue to Q2=5.5, x=0.5 (pi+) kinematics
    • For pi+ running, we are trying to match the SHMS 3/4 rates that we saw for pi-
    • For Q2=5.5, x=0.5, this means our target 3/4 rates should be:
      • z=0.6: 440 kHz
      • z=0.5: 500 kHz
      • z=0.4: 500 kHz
  • Arc energy measurement tentatively scheduled for Wednesday

Notices in Effect for Shift Crew

  • Monitor SHMS 3/4 rates - maximum rate 500 kHz.
  • HMS polarity cannot be changed remotely - requires hall access. (Note: no polarity changes need for CSV).
  • When setting HMS Q1, always reduce current in steps of 50 A or less.

Current Issues

  • Need to melt some ice on SHMS current leads at the next opportunity

Planned Accelerator Configuration Changes

  • None
