laser calibration

Simulation of a laser calibration system for TORCH prototype.

  • torch prototype
  • prttorch simulation. comparison with test beam data 2022
  • geometry dimensions are from torchsim/TORCH_drawings
  • implemented MCP-PMTs detector plane (1x11 PMTs with 8x64 pixels each)
  • optical photons @ 3.2 eV (387 nm)
  • 100 ps time precision
