- DIRC@EIC design; 11 bars; 4x6 MCP-PMT array; 3-layer sperical lens with nlak33
- 3 mm pixels HIQ400, CE=95%
- 100 ps time precision
- time imaging reconstruction with simulated PDFs (30k for each particle type)
- geometrical reconstruction with averaged LUT from 5M photons
- 0.8 tracking resolution. See track resolution scan for more.
Post-dirc tracking layer located few cm away from radiator. Points p1 and p3 are smeared with 50 mkm in X and Y. Resulting vector (p3-p1) is used as corrected track direction. Event display for 0.2 GeV/c pion @ 30 degree hitting 30 mm wide bar:
Geometrical reconstruction (tracking layer 1.5 cm away from radiator):
Without post-dirc tracking:
