Agenda

  1. Ciprian : preliminary results for transverse run spreadSheet atPlots
    • Devi:cos(phi) is from PREX-I. CG: will cross-check.
    • KK: we are not going to present An-hat (impurity corrected) next week.
    • David A: I checked - the PREx point in the original version of the paper was plotted with the error bar being total (stats + syst added in quadrature): 0.28 +- 0.25 ppm
  2. Don : Discussion on Moller result during transverse run Moller elog or Ace Elog
    • KK: what's the total error from polarimetry. CG: about 2% relative error.
  3. Paul: Initial look at drifts in BCM event-level difference; follow up needed. http://ace.phys.virginia.edu/HAPPEX/4162
    • TY: run 3454, the rising behaviour only happens in analog upstream BCM
    • CP: there is a power supply replacement in the BCM. Majority of the runs happen before power supply replacement.
    • GU: is there any intensity dependence. PK: No.
    • GU: is the beam current at normal run condition. PK: these runs are in typical beam current.
  4. Victoria: glance at PREX-II statistics including bmod data
