500 GeV transverse ZDC Polarimetry Run QA

I have tried to QA the 500 GeV ZDC polarimetry runs.  If you go to the run page, for example, for 10075024 it is:

HOWTO: Use pythia 6xx in ROOT

Root's TPythia6 interface allows the user to run pythia only simulations within root.  By default, root will load a given version of the pythia library.  At present it is version 6.4.16

Cuts and calculation for Z invariant mass

The Z invariant mass plots are generated by looping over every pair of tracks that are associated with a common primary vertex:

-Both tracks must have at least 10GeV.

Pi0 energy distribution from Pythia

Run 10 MDC, testing data rate to HPSS

General

At every HPSS software revision (API changes), the experiment re-test the data bandwidth to ensure rates and functionality under a minimal test period of 24 hours, can be sustaine

HOWTO: Perform basic sanity checks on pythia in starsim

Pythia contains a subroutine PYTEST, which is a fully-functional pythia program.

HOWTO: Check for overlaps / extrusions in a geometry using TGeoChecker

Root's TGeoChecker class provides some useful functions to check for errors in geometries.

 * --===================================================================--*

     Agenda:

     1) Run10 preparation: Bill
     2) LPV news release discussion - Draft(V3).doc and comments from Jack: Jack_message.pdf; Jack_release.doc
     3) STC candidates and LFSpectra PWG co-convener candidate - Nu
     4) Publication policy - Jerome

           *--====================================================================--*

     Brief Summary:

      0) Attendency: Olga, Flemming, Jerome, Jamie, Nu, Bill, Helen

      1) Run10 status: STAR is progressing smoothly. By Saturday, TPC laser will be ready; Magnet on over the weekend.

          Run10 trigger: data volume for 62 GeV // PMD data:

          CAD: beam in Blue. Thursday evening, beam will be in Yellow.

      2) LPV news release: make a merged version and send it to Steve et al.

      3) Publication policy seems not work at the moment. Should modify the policy?

         PWG: ?         Council representative at each group?         Policy amendment?

         Nu: (i) Ask STC chair to cc the nomination to each council representative; (ii) encourage PWG co-conveners

               pay more attention on talks; (iii) Bedanga summarize the responsibilities at each stage of a STAR talk, start

               tracking.
