Agenda

1. Timing Update - Gary Penman

1. Roundtable - all

Attendance

Arun, Kate, Jack, Vimukthi, Silviu, Hunter, Saru, Andrew Cheyne, Andrew Puckett, Bogdan, Brayan, Gary, Xiaochao, Nilangs, Bhashitha, Jacob, Jiwan, Todd, Bill

Minutes

Gary's talk:

• position dependence (HCal module of Hodo bar) of coincidence time (HCal TDC - Corrected Hodo TDC)
  • groups of HCal blocks show patterns
  • some kind of wiggle in timing shift
• Even the current state of the calibration is visible in the final physics
• there are time shifts across kinematic configurations

Roundtable:

• Braian - going over Hunter and Sean analysis to learn more, full time analysis starting next year
• Gary - thesis and timing (first draft of thesis done!), thesis will be submitted at the end of the year
• Hunter - polarimetry and thesis work, moving soon (yay, congrats!)
• Jack - GRINCH track matching and improving PID, how to use grinch cuts at higher Q2, helping to solve mysteries
  • Eric made a helpful presentation for bbcal digitization [1]
• Jacob - elliptical cuts on scattered e energy vs angle - obtaining cut definitions from simulation
• Kate - NIM paper and BBCal timing
• Vimukthi - looking at energy cuts and looking at kin4

Bogdan comment: dead time between helicities - need correction for change of IHWP? look at pion events and see how they vary with helicity (did Sean look into this?)
