Agenda

  1. Devi: PMT non-linearity bench test HAPLOG 4170
    • KP: is DAQ at the same setting as normal run? DA: Yes.
    • KK: Have we tried leaving PMT on for a day long then performing measurement? DA: We tried hour long warming up and we have temperature sensors.
  2. Ciprian: Transverse asymmetry summary spreadSheet
    • CG: we need further work to correct asymmetry sign
    • David A: is it blinded? CG: No.
    • Devi A: the target impurity is Carbon rate divided by Pb rate
    • KK: we can have straight average from Moller and Compton results instead of weighting average.
    • David A: is the transverse spin direction perfectly vertical? CG: based on Mott results, I think it is within 2 %.
    • KK : We can tell this from the average.
    • PK : transverse spin direction will affect loss in analyzing power. KK: HRS acceptance will make difference as well.
