Present: Alexei, Yuri, Gene, Flemming, Mike, and myself

== Hardware

— finished cleaning of all TPC except 12 points on east side

— interrupted by water leak

— expected that leak will be fully repaired this week

— Tonko nothing with TPC until Jan. 1st

— plenty of time for Alexei to finish work

== Electronics

— nothing new reported this week

== Software

— Yuri finished with dE/dx calibration (7.7 and 9.2 from 2020)

— will put calibration constant in dB and request production

— will prepare calibration for entire BES data set

— some other activities ongoing around combined PID (from all detectors)

— Guannan is continuing work on deep tuning of TpcRS

— Gene mentioned Babu has started working on SC and GL

== AOB

— Flemming mentioned minutes from QA 

— Run 20192001 shows anomalous drop in sector 1 in phi vs. eta

— not easily seen in QA plots (small)

— sector 1 had many auto-recoveries in that run

— seems that one RDO does not come back fully resulting in an inefficiency

— likely need a new QA plot to help identify this problem in the future

Best Regards,

  Richard
