Performance compassion for different pixel size. pi/e
- DIRC@EIC, EPIC
- 3-layer spherical lens with sapphire, r=[62,36]
- 8x8 vs 16x16 (3.3mmx3.3mm vs 6.6mmx6.6mm pixels) HIQ400, CE=95%
- pion/electrons @ 1.2 GeV/c; phi = 0 (no field); vertex y-shifted by 0.5*barwidth (to hit middle of the bar)
- 2.2 mrad tracking
- 100 ps time precision
- geometrical reconstruction with averaged LUT from 15M photons
- GR with per-PMT and chromatic corrections
- 22.5k tracks for pdf generation (per each particle species); 5k for determining separation
