cern layout with 256 pixels

DIRC@EIC prototype simulation with CERN18 beam parameters. 8 MCP-PMT's layout.

  • 8 vs 12 PMTs layout with 3mm x 3mm (256 pixels) vs 6 mm x 6 mm (64 pixels) pixels
  • bar with 3-layer spherical lens
  • 1 cm beam diameter
  • protons, pions @ 7 GeV/c
  • geometrical and time imaging reconstruction
  • 100 ps vs 200 ps time precision

Performance compared to 64 pixel MCP-PMTs:
