Agenda

• 1. Simulations for GEn-II -> Sean Jeffas [1]
• 2. Summary of Moller measurements for GEn-II experiment -> Faraz Chahili
• 3. BBCAL plots with and without GRINCH cuts -> Kate Evans [2]

Attendance

Arun, Kate, Hunter, Sean, Todd, Faraz, Gordon, Gary, Jiwan, Andrew, Jack, Nilanga, Bogdan, Jimmy

Minutes

Sean's talk:

• updated target geometry
• is target too close to target frame?
  • check positioning, the ladder is too close to the target
  • how thick are the shims between the target ladder and transfer tubes?
• generic target geometry doesn't affect neutron efficiency
  • important for backgrounds
• we need the following generators:
  • elastic eN with radiative methods (SIMC)
  • inelastic to look at inelastic cross sections (g4SBS)
  • inelastic for pion electroproduction (MAID)
• how will we calculate asymmetry from simulation?
  • need Misak's code to fold in all nuclear effects
  • how many "false" elastic events do we have?
  • event-by-event asymmetries are very computationally costly
  • effective neutron polarization might not be enough
  • how often do we need polarization values supplied?
    • Bogdan suggests every 20 minutes
  • need correction for field direction for GM
• implementation of SIMC underway
  • needs updated target geometry -> Mark Jones

Faraz's talk:

• is there any transverse polarization?

Note: Gordon has a graduate student who would like to work on GEn analysis.
