Detailed Description

A specialized Device class for modelling radiative losses.

Definition at line 32 of file Bremsstrahlung.h.

Constructor & Destructor Documentation

Smear::Bremsstrahlung::Bremsstrahlung ( double  epsilon = 0.01,
double  traversed = 10.,
double  radLength = 47.1 
)

Constructor. Photon energies are randomly generated in the range [epsilon, E - epsilon] for particle energy E. traversed is the distance of material through with the particle passes and radLength is the radiation length of that material (both in cm).

Copy constructor

Member Function Documentation

Bremsstrahlung * Smear::Bremsstrahlung::Clone ( Option_t *  option = "not used") const
virtual

Returns a pointer to a duplicate of this object.

Definition at line 96 of file Bremsstrahlung.cxx.

double Smear::Bremsstrahlung::dSigmadK ( double *  x,
double *   
)
protected

Returns dSigmga/dK at k = x[0]. The arguments have this form to interface with ROOT::TF1. The second argument is unused.

Definition at line 44 of file Bremsstrahlung.cxx.

int Smear::Bremsstrahlung::NGamma ( )
protected

Compute the number of photons emitted.

Definition at line 65 of file Bremsstrahlung.cxx.

void Smear::Bremsstrahlung::SetParticle ( const erhic::VirtualParticle &  prt)
protected

Set the radiating particle type and configure the dSigma/dK function.

Definition at line 78 of file Bremsstrahlung.cxx.

bool Smear::Bremsstrahlung::SetupPDF ( )
protected

Configure the dSigma/dK function, setting the energy range over which to generate photons. The energy range is computed from the energy of the current mParticle. If the resultant energy range is invalid (e.g. max < min) the range is not set and the function returns false.

Definition at line 53 of file Bremsstrahlung.cxx.

void Smear::Bremsstrahlung::Smear ( const erhic::VirtualParticle &  prt,
ParticleMCS &  prtOut 
)
virtual

Smear the properties of a Particle and assign them to a ParticleS.

Reimplemented from Smear::Device.
