HDGeant4 Meeting
Friday, July 6, 2018
10:00 am
JLab: CEBAF Center, A110
BlueJeans: 968592007


  1. Purpose of these meetings (all)
  2. Issues on GitHub (all)
  3. Meeting Schedule



  • FSU: Sean Dobbs
  • JLab: Thomas Britton, Justin Stevens, Simon Taylor, Beni Zihlmann
  • KDH: Mark Ito (chair)
  • UConn: Richard Jones


  • Thomas has not had a chance to get to the bggen sample using HDG4.
  • Sean: high level comparisons of HDG3 vs. HDG4 with bggen not useful, too much going on
    • Use pure, simple reactions: e.g. ρ, φ production
    • Justin: single particle gun an option too
      • charged particles
        • FDC
        • CDC
        • transition region
      • photons
        • BCAL
        • FCAL
  • Sean: want to use latest version of software, old versions have old software problems
  • Justin: we should set some milestones
    • by detector? I. e., FDC, CDC, BCAL, FCAL, TOF
    • Sean: can do comparisons with monitoring histograms
      • has some ready to go, will publish them
  • Someone: comparisons might be easier with no smearing
    • Sean has scripts to look at raw HDDM as generated by HDG
    • Smearing can be turned off in mcsmear easily
  • Need new version set for comparisons
    • look at doing a new release of HDGeant4
    • wait for Simon pull request before tagging
    • tag pre-split sim-recon repository, not post-split halld_sim + halld_recon


Future Meetings

  • next meeting in two weeks at same time
  • will meet every two weeks until further notice
