— Gene working on dE/dx production for Run22 pp500

 

 

    The  production for Run22 pp500 does not have *event.root files, and thus it  cannot be used for dE/dx calibration.

See, for example,

/star/data113/reco/production_pp500_2022/ReversedFullField/P24ib_calib/2021/355/22355023/

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

 

 

Present: Alexei, Jim, Gene, Emmy, and myself

 

 

== Hardware

— working on east laser

— poletip to be closed about 20th of Feb.

— gas system has enough methane and argon for run

 

 

 

== Electronics

— Tonko mentioned some problem with sector 24

— two side-by-side RDOs, one was less efficient at reconstructing hits

— no obvious correlations, unclear why one RDO is less efficient

— still under investigations

— Flemming working with Isaac Mooney to produce some automated QA for TPC

— Gene helped setup in FastOffline

— was a great help last year, much less work for Flemming during run

 

 

== Software

— Gene working on dE/dx production for Run22 pp500

— some discussion of twist (ExB) correction 

— Emmy’s work on mass differences

— see slides sent to list

— looking specifically at vertical track mass difference

— some definite improvement after sector alignment work

— some irregularities in m^2 vs pt in edge plots

 

 

== AOB

— Nothing additional reported this week.

 

Best Regards,

  Richard
