Present: Alexei, Jim, Gene, and myself == Hardware — some misalignment on east laser — will address next Thursday — DV looks okay so far — some variation vs. methane, trying to stabilize — gas system is stable — otherwise TPC is running well

== Hardware

— some misalignment on east laser

— will address next Thursday

— DV looks okay so far

— some variation vs. methane, trying to stabilize

— gas system is stable

— otherwise TPC is running well

== Electronics

— 3 days ago was harsh background, losing several RDOs per day

— at present background are much lower, RDOs more stable

— only one RDO lost overnight (already repaired)

== Software

— L4 trigger folks mentioned seeing strange signed DCA this past week

— fast offline did not report the same

— perhaps was wrong magnetic field setting?

— does not seem to be a TPC calibration issue

— O+O is moving, will be done at the end of the week

== AOB

— Yesterday was supposed to be 6x6 store for sPHENIX, but did not happen

— would also be useful for STAR calibrations if it can be run

Best Regards,

  Richard
