Current Status
- Currently in Controlled Access during the RF recovery
- HMS Q1 power supply. Ellen replace the signal conditioner: https://logbooks.jlab.org/entry/4097300
- Helium-3 pressure problems: https://logbooks.jlab.org/entry/4097562
- Likely a leak in the Helium-3 cell which was fixed by Dave
- Warm up and recover Helium-3.
- Fill Helium-3 cell with Helium-4 and check for leaking over the next several days.
- If it appears stable, return the Helium-3
- Or if the leak is fixed, leave at the pressure it currently is
- Target boiling study: SHMS at 20.0 degrees (-4.4 GeV) and HMS at 20 degrees (-4.4 GeV)
- Finished He-3, He-4, Dummy, and limited carbon before beam stopped at 8 am.
Run Plan
-
Target Boiling - BCM Calibration?
- Energy Measurement?
