RC summary September 23 - September 29, 2021
There was no beam for a little bit more than half of the week. We lost 4 hours when the beam was available to debug the tagger microscope (there was a wrong cabling issue). During the downtime, a dozen FCAL channels were required to be debugged, by either replacing a PMT or more frequently a base. Throughout the week, HV was changed in different detectors: TOF, TAGM & FCAL. During this week, the PrimEx physics production started with Be target (50 nA) and CDC & FDC turn on aka FDC straight track run for 2.5 shifts. Then, we continue for 2 shifts to take data with the chambers off and the beam current increased to 100 nA. Finally, we started the 10 shifts chunk of 200 nA Be data set.
