Agenda
- Announcements
- Hardware work (All)
- Latest inspections of mirror prototypes: one more planned for December 2021
- DIRC light leak check instruction
- Review of 2020 studies (All)
- Spring and Summer 2020 data production status all complete but ongoing issues with tape and Analysis launches
- Geometric reconstruction update (Roman)
- Simulation needs:
- Ad-hoc reduction in photon yields (in mcsmear) to match data: until mirror reflectivity dependence on incident angle is implemented
- Tagged version of halld_sim with any updates (version set compiled against halld_recon 4.16.2 used in data production)
- Others
- Action items (from previous meetings)
- Add incident angle dependence to mirror reflectivity
- Global alignment issues see slide 15-18 of CM talk (All)
- Early studies of FDC tilt
- Possible rotation of magnetic field: impact on extrapolations to DIRC?
- Generate MC with rotated field and reconstruct with nominal?
- Reducing background contamination in pi/K samples: KinFit Δχ2 between 2pi and 2k reactions, robust sideband subtraction
- FastDIRC documentation (Yunjie)
- AOB
