<p>During the maintenance day yesterday, we accomplished the SBS magnet acid flush, carbon hole target change and fixing issues with different detectors. After all the work, hall was taken to controlled access around 6pm. During the controlled access, HCAL hardware is checked again to make sure that it's functioning well. Around 7pm, hall was taken to beam permit and we got beam to the hall after 9 pm. Beam recovery procedure wall followed thoroughly, and it was completed around early owl shift. New carbon hole center is found at (0.8,-1.1) <a href="https://logbooks.jlab.org/entry/4184156">https://logbooks.jlab.org/entry/4184156</a> along with the previous SOFs. After that MCC struggled to send the CW to the reference cell during the whole owl shift. As planned, Moeller experiment was started from the early day shift today.</p>
<p>During the owl shift we had three issues in our side: 1) FSD engaged due to cooling jet (found out that it's intermittent only) 2) SBS GEMs made DAQ unstable, so changed to NoSBSGEMs config. 3) hodoscope alarm going off even though HV is okay (EPICS not subtracting SET - READBACK for alarming)</p>
<p>We will have RC meeting in the CH conference room starting from 3:30pm to discuss details. You could also join remotely with the following info:</p>
