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

== Hardware

— Access yesterday

— tuned east laser for more power

— Trips appear to be result of beam dumps 

— during very hot days we are running only half field to compensate for difficulty cooling the magnet

— high temp policy seems to be working

— some maintanance work was also done on power supplies

— humidity does not seem to be problem (only about 38% in IFC)

== Electronics

— Tonko was out for a period but restored all RDOs but two that were dead yesterday

— went from 7 RDOs out to only 2

== Software

— TPC SC

SC not yet done for half field so fast offline has wrong SC correction at present

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

— ran into memory issues on the farm

— should be finished soon

— TFG25e release

— see https://drupal.star.bnl.gov/STAR/event/2025/07/17/STAR-Weekly-TPC-Meeting

— versions for SL7 and Alma Linux (with Root 5.34.39 and 6.37.01)

— Alma Linux version required new cernlib (works but need to check how well)

— GEANT 3 geometries were revisited (now with tag z)

— next will run some small samples to do track-by-track comparison between 32 and 64 bit versions

— need more disk space for full sample

— CPU comparison shows significant (25% or better) speed-up with Alma Linux vs SL7

== AOB

— Nothing new for this week

Best Regards,

  Richard
