• G4HRS Simulation - Documentation, Github
• HAMC Simulation - Notes, tech-note, formulae, Github

HRS Analyses

• Bob's October 2019 analysis plan, Kent's October 2019 plan, Ryan's October 2019 Update (most useful starting point), Ryan's FOM calculation for CREX notes
• Notes from Tyler: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,

Analyses Projects

• Optics Database Tuning - Ryan, Siyu, etc.
• Acceptance Function - Ryan, Chandan, Bob, etc.
  • PREX I notes from Bob
  • Average Q^2 from Analyzer and Simulation - Devi, Ryan, Dustin
  • Inelastic backgrounds and contamination - Ryan, Devi, Hanjie
  • Radiative corrections for APV extraction - Hanjie
• AT extraction, verification in Analyzer and Simulation - Ryan, Devi, etc.
• Rescattering, Pole Tip backgrounds, and more - Devi, Bob, etc.

Outstanding Issues

• Super-elastic tail in G4HRS simulation but not in the Analyzer data
• Related, questionable quad magnetic field implementation in G4HRS (see some of Tyler's notes above for reference)
• Raster / BPM corrections for Analyzer Database
• Consider two ways of tuning HRS database w/ & w/o septum co-tune
• Are radiative corrections handled properly in G4HRS
• Target implementation is simplistic in G4HRS (and needs to be update to do diamond foil + Pb simultaneously)
• Inelastic states may need additional attention in G4HRS
• Difficult to recreate the hard collimator cut seen in the data with G4HRS
