Current Status

On the accelerator side:

--> Ops took the machine offline for retuning since yesterday morning. It has been a very, very long process. As of 11:38 am we still haven't seen beam to the Hall A dump. https://logbooks.jlab.org/entry/4281320

On the Hall side:

--> Dave Meekins condensed H and D overnight. The target was ready shortly before 5 am. We took Hall A to beam permit at 4:49 am.

--> Faraz trained the Moller solenoid up to 60 A: https://logbooks.jlab.org/entry/4281224
