Update on BB GEMs(Sean, Ezekiel, Holly, Anu)
- GEM Alignmnet - Sean
- UV replacement layer is in INFN test lab on nitrogen. HV has been tested. Unclear when we will install (depends on Jessie for support). Resistor replaced photo
- Current BB/SBS experiment status: https://logbooks.jlab.org/entry/3932961
- 10uA on deuterium in last SBS kinematics (highest currents/occupancies so far): https://logbooks.jlab.org/entry/3931870
- BB GEMs currently back on nitrogen while Hall A work is ongoing https://logbooks.jlab.org/entry/3932943
- GEM HV supplies disconnected yesterday for Hall A work https://logbooks.jlab.org/entry/3932945
- BB GEM gas switches ok now. Still plan to calibrate the mixing unit in the future with Jack, but probably lower priority than the Hall A issues.
- INFN trip limits https://logbooks.jlab.org/entry/3931889
- Currents and set voltages in the EPICS archiver as of Monday https://logbooks.jlab.org/entry/3932174. This was always reported as a snapshot in the HALOG with the BB EPICS start of run entries.
- Replay plots post to logbook automagically. Example here: https://logbooks.jlab.org/entry/3932008
