transport efficiency with scaled RC

Performance of the hpDIRC under different assumptions for transport efficiency. See also transport-efficiency

  • EIC, ePIC, hpDIRC
  • with B-field
  • tracks hitting middle of the bar #5
  • 3-layer spherical lens with sapphire, r=[62,36]
  • 4x6 layout; 16x16 pixels MCP-PMTs with HIQ400, CE=95%;100 ps time precision
  • transport efficiency based on BaBar ref. coef. measurements
  • geometrical reconstruction with averaged LUT from 15M photons
  • TI with 20k PDF for each particle type. PDF generated with corresponding bar shape.
