theta vs bar

Performance as a function bar id. Vertex is at (0,0,0) (no shift), targeting center of each bar. With and without B-field.

  • DIRC@EIC, EPIC
  • 3-layer spherical lens with sapphire, r=[62,36]
  • 16x16 pixels MCP-PMTs with HIQ400, CE=95%
  • pi/K @ 6 GeV/c; phi = 0 (no field); theta = 30 deg
  • 100 ps time precision
  • geometrical reconstruction with averaged LUT from 15M photons
  • GR with per-PMT and chromatic corrections
