Run Coordinator's Report for Friday November 27 Day to Saturday November 28 Owl

Summary

We took 20 hours of ABU over the last 24 hours in which we completed slug 9 and achieved ~150 K good LD2 pairs for slug 10.

There were beam quality concerns and a high trip rate during Swing shift. MCC raised the Compton ion chamber trip rate. The Compton rates have deteriorated significantly since Wednesday, the high voltage has been lowered to 1400 V. We will ask MCC to tweak the injector.

Today there will be some dead time studies for about 2 hours at variable currents.

Tomorrow there will be Compton studies for about 3 hours at low current, possibly combined with opportunistic Q2 measurement and Moller.

4 Owl shifts in the next week need a shift leader. Please sign up!
Shift Leaders: please write a detailed shift summary (including runs taken and any activities) and submit the BTA for each shift. Please log CODA reboots in the halog and shift summary.
3rd person: Please make sure to start and stop the HRS DAQ at the same time as the parity DAQ and to do the prompt analysis and the HRS analyzer for every run.
3rd person: please keep a careful eye on the online data display. Most problems can be caught quickly this way.
Please make sure that the shift checklist is done once each shift.
