[Richard Witt <witt AT usna.edu>]

Present: Alexei, Flemming, Gene, Frank, and myself

== Hardware

— TPC running well

— lasers okay

— looking at gas system long term trend

— gas pressure slowly decreasing, will work to stop current decreasing trend

— checking 6-pack bottles individually

— t-storm this past Tuesday, pressure jump of ~1.5 mbar

— gas system did not go into purge mode

— some sector trips, may want to lower voltage, do not want to change current limit

— could also try lowering voltage by smaller amount (~20V vs 45V)

== Electronics

— high rates and luminosity produces fluctuations in RDOs and FEEs as they fail and are fixed

— down to about 2 RDOs at present (9 is the max so far) 

== Software

— TPC SC

— Baoshan working on SC in current run (HLT software)

— numbers are in dB (preliminary for ongoing run)

— Run 24 low-lumi p+p now a production priority

— should be finished next week

== AOB

— Yuri has requested SVT drawings to ensure the support cone is properly represented in simulation

— important for FXT running

— after Yuri finishes shift, will arrange meeting to discuss drawings

Best Regards,

  Richard
