Function documentation
AliTRDsimTR(AliModule* mod, Int_t foil, Int_t gap)
AliTRDsimTR constructor. Takes the material properties of the radiator foils and the gas in the gaps from AliModule <mod>. The default number of foils is 100 with a thickness of 20 mu. The thickness of the gaps is 500 mu.
void Init()
Initialization The default radiator are prolypropilene foils of 10 mu thickness with gaps of 80 mu filled with N2.
Int_t CreatePhotons(Int_t pdg, Float_t p, Int_t& nPhoton, Float_t* ePhoton)
Create TRD photons for a charged particle of type <pdg> with the total momentum <p>. Number of produced TR photons: <nPhoton> Energies of the produced TR photons: <ePhoton>
Int_t TrPhotons(Float_t p, Float_t mass, Int_t& nPhoton, Float_t* ePhoton)
Produces TR photons using a parametric model for regular radiator. Photons with energy larger than 15 keV are included in the MC stack and tracked by VMC machinary. Input parameters: p - parent momentum [GeV/c] mass - parent mass Output : nPhoton - number of photons which have to be processed by custom code ePhoton - energy of this photons in keV.
Double_t Sigma(Double_t energykeV)
Calculates the absorbtion crosssection for a one-foil-one-gap-radiator
Double_t GetMuAi(Double_t energyMeV)
Returns the photon absorbtion cross section for air Implemented by Oliver Busch
Double_t Interpolate(Double_t energyMeV, Double_t* en, const Double_t *const mu, Int_t n)
Interpolates the photon absorbtion cross section for a given energy <energyMeV>.
Int_t Locate(Double_t* xv, Int_t n, Double_t xval, Int_t& kl, Double_t& dx)
Locates a point (xval) in a 1-dim grid (xv(n))
