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
