Logentry Text:
After the beam studies yesterday, beam came back around 8pm due to a NL pressure and cavity issues. We asked for Harp scan with H07A  and H07B. H07A failed to scan, but we got results with H07B (https://logbooks.jlab.org/entry/3557594) and 3C20 (https://logbooks.jlab.org/entry/3557599). System expert will look into the H07A issue today. After Carbon Hole spot check (https://logbooks.jlab.org/entry/3557613), we resumed production.

Smooth running over night and we finished data taking for Deuteron Electro-Disintegration (E12-10-003) Run Plan. We collected ~75% of data for the Pm=750 MeV. We will switch to the SIDIS today.

At 8am this morning, SHMS magnets failed followed by ESR problem which seems to be triggered by the magnet problem. LHe levels are recovering and magnets are slowly coming back. Steve Lassiter came in and he went down to the Hall to check magnets.

RF recovery has begun at 9:00. We will go in Restricted access for the Aerogel tray change which requires using s a truck ramp. RadCon is here, and the Hall will be open around 10:00 am. If you have work to do in the Hall, please stop by the Counting House and let the Shift Leader know. 

We will meet in 200C at 1:30 pm (second floor of the counting house).
