Agenda

1. SBS optics and HCAL calibration summary for all GEN kinematic points - Vimukthi Gamage

Attendance

Vimukthi, Kate, Arun, Bogdan, Jack, Gordon, Nilanga, Braian, Mahmoud, Saru, Faraz, Silviu, Gary, Huong, Jiwan, Dulitha

Minutes

• direction and magnitude of proton momentum
  • position reconstruction - is this done? what is the resolution?
• is field integral adjusted?
• cut on delta Pn plots for the horizontal variables?
  • how good do we need to get for the HCal calibration?
• momentum resolution? ~3-4%
  • good to show this
• slide 6 is comparison of target vertex from electron arm tracking vs from hadron arm tracking
• why do we see the spikes in the plots on slide 10?
  • geometric relation?
  • spatial relation?
  • issue with clustering?

  • need to have a clear explanation for these spikes
  • most events have small clusters so the energy weighted center is basically the center of a block
