RC Report 25 June 2022

General Summary

- no beam the most of the day
- at ~20:20 beam was back. Harp scan done and approved.
- Moller measurements (two target polarization) 
-- 74.7 +- 1.5 % --> https://logbooks.jlab.org/entry/4006973  
-- -92.8 +- 1.5 % --> https://logbooks.jlab.org/entry/4006973
- empty target run
- accelerator dowm at 08:00 due to vaccuum leaks from an old known, 2L12. 
- News from the PD Yan and Uberboss Doug. IF everything goes fine, we can have Spin Dance tomorrow (Sunday). The bigger picture is today Hall D will do the tagger measurements, tomorrow the Spin Dance, and Monday with all the experts, they will push to provide higher current to Hall C (I guess you know what that means).
