mcp-pmt vs hrppd

Performance comparison for different type of PMTs. MCP-PMT vs HRPPD.

  • PandaRoot simulations without field
  • configuration with narrow bars, 3 layer spherical lens
  • 8 MCPs layout with ~17 mm gap vs 2 HRPPD
  • pions and kaons @ p = 3.5 GeV/c @ phi = 10.825 deg
  • 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
  • QE=18(24)% and 26(32)% ( blue curve). CE=95%
  • spatial QE = 1
