Yesterday, work was performed to plug the leak allowing water into the electrical box. A sealant was applied and allowed to cure over night. The good news is that it seems to have worked, and the box is now dry. We are planning to restore power to the hall this morning, pending the completion of a few other tasks to button everything up. Once power is back on, we will begin doing the work to ready the Hall for beam operation, with the goal of resuming data taking Saturday. 

In terms of other work in and around the hall:
- Holly has been working to solve the issue of the high current draw on one of the GEM sectors. See:

SHIFT SUMMARIES:

No shifts

RUN PLAN:

If all goes well, we restore power this AM, and then begin the work to restore the vacuum, cryo, magnets, spectrometers, etc.  We aim to begin restoring beam to the hall on Satuday day shift. 

Once, we are back online...we would like to take a few hours with carbon multifoil at 1 uA for calibration, but then we plan to continue production with D2, with single arm measurements once per day.

NOTES FOR SHIFT TAKERS:

Please keep an eye out for further shift cancellations. The situation is evolving, and I thank you for your flexibility.
