Run Coordinator report: fall 2022 w9

The week of Oct-19-26 started with Beam down for ARW Tour and Associated Maintenance Day. During this event some activities were conducted in the hall: replacing Fcal bases (Mark&Malte), work on PS test stand (Vlad&Arshak), GEM-TRD (Kondo).

Oct-19 at ~22:30 beam is back, we asked MCC for Harp Scans. Then started taking production data on Empty Cell Target until Friday Swing. There were target issues on Friday swing, the Pulse Tube Refrigerator (PTR) switched itself off resulting in increase of the target cell temperatures from 4.27 to about 4.6 K, informed Chris Carlin, late evening Chris C came in to check the heater/cooler box. After he cycled the target GUI from hall, everything was fine. Continued taking data on LHe Full target. Around midnight of Saturday during run_111140 one of FCal fADC was found broken, contacted Sergey, he removed it from triggers, until experts will replace the broken fADC. On Saturday around noon, asked Rapid Access to let A. Somov replace the FCAL fADC. Mostly no other major issues during the weekend. There was injector slit water flow interlock issue during Monday OWL shift, which affected to beam down for ~5hrs. On Tuesday Oct-25 around 9am we emptied the target and continued taking data on empty cell target until next maintenance day. On Wednesday early morning “VTP5H00SPD” vacuum pump tripped, contacted on call expert, ~4:00am entered to Tagger Vault with the MCC/ARM, rebooted the pump. There were some issues with DAQ, and FCAL bases some of them have been taken care of, some will be checked during next “Maintenance day”. Overall beam was stable when it was ON.
