Comparison of the Barrel DIRC 's performance for configuration with optical grease and air gap between prism and MCPs.
- PandaRoot simulations without field
- configuration with narrow bars, 3 layer spherical lens, and 8 MCPs layout with ~17 mm gap
- pions and kaons @ p = 3.5 GeV/c @ phi = 10.825 deg
- time-imaging reconstruction with full-simulated pdfs
- 30k tracks for pdf generation (per each particle species); 5k for determining separation
- ~2 mrad tracking resolution
- realistic time precision
- QE=18(24)% and 26(32)% ( blue curve). CE=95%
- spatial QE = 1
Low QE (QE=18(24)% black curve). CE=95%
