performance map for 3LC

Performance of the Barrel DIRC as a function of the polar angle and momentum for a design with cylindrical 3 layer lens and 8 MCPs layout.

  • PandaRoot simulations without field
  • configuration with narrow bars, 3 layer cylindrical lens, and 8 MCPs layout
  • pions and kaons @ phi = 10.825 deg
  • geometrical reconstruction with 2M LUT
  • 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
  • standard wavelength QE
  • spatial QE = 1
