Time imaging performance as function of lens's radii.
- DIRC@EIC, EPIC
- tracking evaluated at r =70 cm with all sub detectors
- 3 mm pixels HIQ400, CE=95%
- pions and kaons @ 6 GeV/c; phi = 0 (no field); vertex y-shifted by 0.5*barwidth (to hit middle of the bar)
- 100 ps time precision
- 20k tracks for pdf generation (per each particle species) (generated with corresponding track resolution); 5k for determining separation
Configuration of 3 layer spherical lens between bars and plate (EV-plate-SL-bars). EV plate has length of 893 mm and height same as radiator bars (17 mm).
