Run Coordinator's Report for Saturday November 28 Day to Sunday November 29 Owl

Summary

• 4 shifts in the next week need a volunteer. Please sign up!


• On Day shift MCC did a brief tweak of some injector parameters which improved the Compton rates considerably.


• A successful deadtime study was done during Day shift for about 3 hours.


• During Owl shift there were muliple magnet trips. Eventually the RHRS Q1 went down and couldn't be reset. Ed made an access today and tried increasing the lead flows but that didn't help. The power supply is suspected and we will have to run with only the LHRS until tomorrow.


• We achieved ~630 K good LD2 pairs for slug 10 in the last 24 hours, some with the LHRS only.

Run Plan

• High current production running throughtout weekend.


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

Requests

• 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.
