Muon light

LumenManufaktur.directlightfrommuonFunction
directlightfrommuon(params::LMParameters, pmt::PMTModel, R, θ, ϕ)

Returns the number of photo-electrons from direct Cherenkov light from a muon with a closest distance of R [m] to the PMT and the angles θ [rad] (zenith) and ϕ [rad] (azimuth) with respect to the PMT axis.

Arguments

  • R: (closest) distance [m] between muon and PMT
  • ϕ: zenith angle [rad] which is 0 when the PMT points away from the muon track (in x-direction) and rotates counter clockwise to the y-axis when viewed from above, while the z-axis points upwards.
  • θ: azimuth angle [rad] which is 0 when the PMT points upwards (along the z-axis) and π/2 when pointing downwards. Between 0 and π/2, the PMT points to the z-axis

directlightfrommuon(params::LMParameters, pmt::PMTModel, R, θ, ϕ, Δt)

Probability density function for direct Cherenkov light from a muon with a closest distance of R [m] to the PMT, the angles θ [rad] (zenith) and ϕ [rad] (azimuth) with respect to the PMT axis and a time difference Δt [ns] relative to direct Cherenkov light. Returns dP/dt [npe/ns].

Arguments

  • params: parameters of the setup
  • R: (closest) distance [m] between muon and PMT
  • ϕ: zenith angle [rad] which is 0 when the PMT points away from the muon track (in x-direction) and rotates counter clockwise to the y-axis when viewed from above, while the z-axis points upwards.
  • θ: azimuth angle [rad] which is 0 when the PMT points upwards (along the z-axis) and π/2 when pointing downwards. Between 0 and π/2, the PMT points to the z-axis
  • Δt: time difference [ns] relative to the Cherenkov light

LumenManufaktur.scatteredlightfrommuonFunction
scatteredlightfrommuon(params::LMParameters, pmt::PMTModel, D, cd, θ, ϕ, Δt)

Probability density function for scattered light from muon. Returns [d^2P/dt/dx].

Arguments

  • params: parameters of the setup
  • pmt: PMT model
  • D: distance between track segment and PMT [m]
  • cd: cosine angle of muon direction and track segment - PMT position
  • θ: zenith angle orientation PMT [rad]
  • ϕ: azimuth angle orientation PMT [rad]
  • Δt: time difference relative to direct Cherenkov light
