Muon light
LumenManufaktur.directlightfrommuon
— Functiondirectlightfrommuon(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 PMTϕ
: 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
