Current Status
- On the second cycle here on p158 of the run plan. Obtained half stats on 40Ca yesterday and finished 3He this morning, going to Al when beam comes back.
- Accelerator was plagued by BLM trips starting Saturday evening. Beam was taken away for most of the day yesterday to try to resolve the problem. Over night, beam continued to be intermittent and often at reduced current.
- Accelerator is currently off as of 0830 this morning to fix a Hall D magnet. The fix has not yet been assessed to be a short or long fix and will likely dictate how long we will be down today. Once that issue is resolved, experts will work to resolve what happened to the beam causing the BLM trips.
- RF recovery day is scheduled for tomorrow day shift.
Current Run Plan
- Continue with run plan at p158: SHMS at 10 deg, HMS at 35 deg on 3He.
Notices in Effect for Shift Crew
- HMS dipole NMR has trouble locking at this setting. Current NMR alarm is disabled.
Current Issues
- Possible issue with 6Li target density. See https://logbooks.jlab.org/entry/4123083

Planned Accelerator Configuration Changes
