fast sim for EIC DIRC

Results of the fast simulation integration into the PID class for the EIC YR.

  • DIRC@EIC design; 11 bars; 4x6 MCP-PMT array; 3-layer sperical lens with nlak33
  • 3 mm pixels (Photonis 2 (CE=95%, QE=22%))
  • base class DrcPidFast

Maximum momentum at which we can get 3 s.d. pion/kaon separation:
