The week from Oct. 30th-Dec. 7th 2022 went well. Most of the time was spent running on filled 4He or empty targets, with in all a total 120.5h of ABU, or 72% of the time scheduled for this week. The beam was quite good, with the only long downtimes being about 7h lost on Dec. 6th to separator and RF problems, and 10h of RF recovery on the 7th. On our side, the only significant problem was Saturday Dec. 4th around 10:15am, when we had a power supply failure for a tagger hodoscope mainframe. This compromised 120 channels on the photon high energy side of the tagger hodoscope. (The crate also services the beam halo monitor in the tagger hall beam line, so we lost those too.) Because we have no off-work-hours electronic support and we did not know initially what was wrong with the crate, fixing the problem was difficult. Many people were called (sometime not immediately successfully owing to the week-end), Richard Jones, Alex Somov, Boris Grube, Benedict Zihlmann, Eugene Chudakov, Tim Whitlatch, Hovanes and Lubomir) but non of them had a contact number for electronic support or, with the exception of A. Somov and Beni, the expertise/availability to help with the problem. This cost us about 6h of ABU. A. Somov was able to come in around noon and accessed the tagger area. However, he could not reset the crate. This was a problem since the knowledge of good crate spares and expertise to replace crates is with the electronics group. Meanwhile, Beni had come to JLab and looked for a spare in the EEL building. He diagnosed that the problem was only with the crate power supplies and had found some spare in the EEL. At 15:45, Beni went in the tagger hall to swap the power supplies. Boris was by then appraised of the problem and went in to help Beni do the replacement. After that, we could restart data taking around 17:00. Beside this major issue, we had the regular usual minor problems such as the need to restart the DAQ from time to time, changes FCal bases regularly, beam/transmission instabilities because the position/energy locks are disabled without us being informed. At the end of the week, we had collected to date 96% of total experiment data (for this Fall 2022 run, and based only of ABU/scheduled time, not data quality) for 89% of the total scheduled experiment.
