- Issues on GitHub (all)
- Meeting Schedule
Notes
Present:
- FSU: Sean Dobbs
- JLab: Thomas Britton, Justin Stevens, Simon Taylor, Beni Zihlmann
- KDH: Mark Ito (chair)
- UConn: Richard Jones
Goals
- 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
- charged particles
- 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
Issues
- Request for DGeometry access for DIRC positions in GlueXPrimaryGeneratorAction
- Richard will work on this one
- TOF hit time distribution shape
- Richard: below thresholds hits are not in HDG4 that might appear in HDG3
- CDC integrated charge shifted to higher values
- This one has been resolved
- Time shift in FCAL showers?
- Richard: t = 0 not the same as interaction time
- there a several suspects for this one
- SCAT card sets vertex position
- Upgrade path for Geant4
- going to a new version is difficult
- we are happy at current version for now
Future Meetings
- next meeting in two weeks at same time
- will meet every two weeks until further notice
