Agenda
- Announcements
- Summer 2022 meeting times
- PrimEx run extended to 11/6/22, so next GlueX-II run with DIRC will be 11/11/22-3/19/23 (followed by long downtime for FCAL-II upgrade)
- Mirror prototype status (Justin)
- FPGA status (Bill)
- Review of 2020 studies (All)
- Analysis Launch ver04 with corrected software for TOF timing and current DIRC corrections.
- Analytic PDF (Roman)
- Geometric reconstruction
- Simulation needs:
- Ad-hoc reduction in photon yields (in mcsmear) to match data: until mirror reflectivity dependence on incident angle is implemented
- 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
