charge dependent timing

Performance of the Barrel DIRC for bars with realistic, charge dependent timing precision.

  • PandaRoot simulations
  • pions and kaons @ 3.5 GeV/c
  • 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 (measured in the lab)
  • standard wavelength QE
  • spatial QE = 1
