keyword=BB HV mainframe replaced, will be down for about an hour due to ESR
The BigBite High Voltage mainframe has been replaced and its now working (thanks for the responsible crew including Jack). We will still be down for about an hour due to the undergoing ESR work. Once the ESR comes back will bring the HRS magnets back on and resume production.
Hall C will be up latter today. Due to that, there may be about an hour of beam stop to Hall A.
Since most of the pending works planned for tomorrows 10:00 AM downtime are already fixed by now, I will propose tomorrows downtime will only be limited for Transverse to Vertical polarization change stuff.
