Agenda

1. [Sean Jeffas] GEN4 Momentum calibration
2. [Faraz Chahili] Preliminary Møller polarimetry results for GEn-II
3. [Paul King] Some remarks on charge asymmetry feedback and helicity readout

Attendance

Arun, Faraz, Gordon, Andrew, Bhasitha, Bogdan, Don, Eric, Gary, Kate, Hunter, Jack, Jiwan, Mark, Paul, Nilanga, Saru, Sean, Todd, Xiaochao

Minutes

Sean's Talk:

• 700 good quasi-elastic events from H2 for GEN4
• We can use momentum calibration from GEN4b on all of GEN4
• Is peak position stable over whole measurement?
  • Residual variation of peak position as a function of x?
• Do the dead regions in BBCal bias our results?

Faraz's Talk:

• 4T field on target
• Look at results from Hall C as a comparison?
• Why did polarization drop after Wein angle change?

Paul's Talk:

• How much of the data is recoverable?
  • 10% of GEN2 data is affected -> need to decide if this is necessary to recover
• Do we need to account for charge asymmetry?
  • Need to look at how large correction is -> can it be neglected?
  • We could treat this time-dependently.
