Yesterday thanks for the quick work of DC power and Hall A staff (thanks Jessie, Bob, Jack!) the 208V transformer was shut down and the output voltage was increased to allow the Moller quad power supplies to function (https://logbooks.jlab.org/entry/3828002).

As we were preparing to get beam back the MBSY1C magnet had a earth leakage fault (https://logbooks.jlab.org/entry/3827999). DC power came back and worked in several shifts (HUGE thanks!) to recover us. Finally at around 10PM they got it fixed (https://logbooks.jlab.org/entry/3828191) and we got back to production. Over night we had some struggles with the RHRS dipole tripping (https://logbooks.jlab.org/entry/3828408) the beam position in the Compton Chicane (https://logbooks.jlab.org/entry/3828386) and hall dpp (https://logbooks.jlab.org/entry/3828424). Our valiant shift crew was up to the task and we made maximal use of the beam time (taking about 1.5C of Left arm running while the RHRS was ramping up). 

As the day shift was starting a replacement for the cold compressor (https://logbooks.jlab.org/entry/3828556) which tripped the CHL. The recovery is expected to take about 4h.

We are going to continue steady production with a short interlude for an alignment check.
