Subject: [Star-tpc-l] TPC Meeting Minutes

 

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

 

== Hardware

— have received a couple additional 6-packs (have 4 full and 1 ~30% now)

— this is about 90 days of supply

— moved 1 6-pack to front of building, sitting on concrete

— may need a roof of some kind

— measurements of TPC supports are complete

— TPC cannot move in north and west direction  

— can move only in south direction 

— will present next week

— west laser failed again

— have 2 spare boards, will check with those

== Electronics

— a couple of boards pulled (sector 4 for example)

— some contacts corroded on RDOs (due to water leak)

— question about corrosion on pad plane itself

 

== Software

— working on SC calibration

— may do an initial calibration and continue working if there is immediate interest

— Yuri sent a link on (i)TPC measurement systematics

— https://drupal.star.bnl.gov/STAR/system/files/Revision%20Tpc%20sytematics%20and%20errors_0.pdf

— see slides for conclusions and plans

— 2D parameterization seems to be insufficient, want to try 4D parameterization

— Gene mentioned there is some priority on FXT productions including 3p85 from Run 21

— may need to account for any new parameterization after those productions

 

== AOB

— Yuri out next week 

 

Best Regards,

  Richard
