We started the week with production running on the empty target. Thursday began with an access during RF recovery and work was done in the hall on parasitic tests on the upstream platform and to replace FCAL bases. During this access the target was filled and we attempted to begin production after taking harp scans on Thursday afternoon. Late Thursday night a power supply in the accelerator had a failure which took the beam away until early Saturday morning. On Friday a TOF HV failed and was replaced by Beni and Sasha that evening. When beam was restored on Saturday morning we ran smoothly over the weekend with the full target cell. We continued running with the full target cell until an accelerator maintenance day on Wednesday morning. On Monday and Tuesday we had a few FCAL bases with communication and voltages that were replaced during Wednesday's maintenance.
The accelerator efficiency this week was about 62%, with ~4 hours of BANU due mostly to DAQ overhead.
