Run Readiness

All of the Hall D Hot Checkout items will be set to "not ready", including the start counter. Mark will go through the checklist. Thomas will observe.


Mahmoud is having trouble doing the propagation time calibration for the Fall 16 Run. It appears that often the wrong RF bunch is being chosen. Sean thinks this may be due to poor timing calibration of the TOF at present. Mahmoud has put the project on hold until he hears more from Sean.

The calibration programs are ready to go for the upcoming run, assuming that all precursor calibrations are in place.

Items for Future Discussion

  • Time-dependent geometry adjustments.
  • Mcsmear procedure and parameters for the start counter.
