RC Report 24 June 2022

General Summary

- Day of upkeep, reparations and testings. 
- We entered in controlled access at 8:15
- Valery has tested a new trigger (v1.2) --> https://logbooks.jlab.org/entry/4006305
- Daniel tested for Helium poisoning in the CTOF PMTs. No evidence of such effect --> https://logbooks.jlab.org/entry/4006344
- target:
-- ND3 cell was tested in situ and it was found some issues with the deuterum NMR, so its use will be delayed. 
-- empty (real empty) target was set to be used in the next days. --> https://logbooks.jlab.org/entry/4006398
- the quadrupoles issue was reported orally that has been found a solution. Extra fans for cooling in the circuits were added. 
- Eugene lead the walk-through training late afternoon.
- when in principle, the beam was expected to be back at 18:00, it hasn't been delivered yet.
- After PD meeting, we were informed that beam will be delivered at the end of the day. Thus the spin dance will be delayed to the next week.
