Performance of hpDIRC with different PMT-prism interface (cookie vs air gap).
- EIC, ePIC, hpDIRC, updated geometry (barrel's R = 766.25)
- with B-field
- tracks hitting middle of the bar #5
- pi/K @ 6 GeV/c
- 0.5 mrad tracking resolution, unless labeled otherwise
- 3-layer spherical lens with sapphire, r=[62,36] for prism EV
- 2x3 layout; 32x32 pixels HRPPD Incom.24, CE=70%; 100 ps time precision
- transport efficiency based on BaBar ref. coef. measurements
- TI with 30k PDF for each particle type.
- eicdirc's git commit hash: 0c96f28
