Propagation time resolution as a function of propagation path length
- DIRC@EIC design; 11 bars; 4x6 MCP-PMT array; 3-layer sperical lens with nlak33
- 3 mm pixels (Photonis 2 (CE=95%, QE=22%))
- without time smearing
- pions/kaons @ 6 GeV/c @ [30-140] deg polar angle
Photons from multiple events (with different polar angle) where collected based on propagation time into different samples and used to determine the TOP resolution. Photon's path distribution:
