Performance of the DIRC@EIC reconstruction for different configurations of the expansion volume. Plate as EV.
- DIRC@EIC, EPIC
- 3-layer spherical lens with sapphire, r=[62,36]
- EV plate is 893 mm long
- 16x16 pixels MCP-PMTs with HIQ400, CE=95%
- pions and kaons @ 6 GeV/c; phi = 0 (no field); theta = 30 deg; vertex y-shifted by 0.5*barwidth (to hit middle of the bar)
- 0.5 mrad tracking
- 100 ps time precision
- geometrical reconstruction with averaged LUT from 15M photons
- GR with per-PMT and chromatic corrections
- 20k tracks for pdf generation (per each particle species); 5k for determining separation
- 893 mm x 175 mm x 17 mm EV prism
