Performance of with different corrections.
- DIRC@EIC, EPIC
- 3-layer spherical lens with sapphire, r=[62,36]
- 16x16 pixels MCP-PMTs with HIQ400, CE=95%
- pi/K @ 6 GeV/c; phi = 0 (no field); theta = 30 deg; vertex y-shifted by 0.5*barwidth (to hit middle of the bar)
- 100 ps time precision
- geometrical reconstruction with averaged LUT from 15M photons
- GR with per-PMT and chromatic corrections
Angle dependent correction
Photon yield after GR
Comparison to old (no normalization, single value) chromatic correction
