Run Coordinator report: fall 2022 w15

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 monitors 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. It was ultimately fixed by Benedict Zihlmann, and this was a stroke of luck, since the problem could well have been beyond the expertise of the Hall D staff. This cost us about 6h of ABU. Beside this, we had the regular usual minor problems such as the need to restart from scratch the DAQ from time to time, more frequent start/stop overheads since many runs are less than the nominal 2h due to CDC pressure alarms, regular change of FCal bases,... At the end of the week, we had collected 96% of total experiment data expected (for this Fall 2022 run, and based only of ABU/scheduled time, not data quality) for 89% of the total scheduled time spent.
