RC Meeting Information
RC Daily Meetings are at 11:00 (am) via Zoom and in person in the counting house meeting room (2nd floor)

Current Issues
- On call list seems incomplete and should be addressed by the Hall: https://logbooks.jlab.org/entry/4230495
- We need other indications of this interlock. In Hall A, we have it shut off detector HV via the alarm handler, and we have a flow rate alarm. Seems the useful PV values have not been working since 1-Sept.
- NPS PMT/Base failures are propagating into columns 9 & 10
