Logentry Text:
The vacuum downtime incident was fixed yesterday and we went to Beam Permit at ~2am.  MCC spent all of owl and part of Day shifts trying to set up tune beam into the hall.  Harp scans were done this morning however the spot size was large ( > 600 µm) and will have to be addressed after the Moller measurement.  Currently we are doing beam centering with the Carbon hole target and then plan to go into Moller commisioning.  After Moller commissioning we will be taking defocused runs in the SHMS in order to calibrate the fly's eye.  The next item in the agenda will then be the BCM calibration.  Tomorrow day we will be doing the Spin Dance with Hall A (assuming the commissioning will be happening soon).

Target work that occurred last night:
A fuse for the oven heater was replaced after the temperature dropped from 200 C to 100 C (https://logbooks.jlab.org/entry/3750923)
The EPR system was tested however a polarization was not measured and is still being troubleshooted.  (https://logbooks.jlab.org/entry/3750991) (https://logbooks.jlab.org/entry/3750996)
EPR software was finished (https://logbooks.jlab.org/entry/3750939)
Target polarimetry is ongoing
