// This class represents the PrimaryGeneratorAction that is used during the
|
||||
//entire
|
||||
// adjoint simulation. It uses the class G4AdjointPrimaryGenerator to
|
||||
// generate randomly adjoint primary particles on a user selected adjoint
|
||||
// source (External surface of a volume or Sphere). The spectrum of the
|
||||
// primary adjoint particles is set as 1/E with user defined max and min
|
||||
// energy. The weight of the primary is set according to ReverseMC theory as
|
||||
// w=log(Emax/Emin)*E*adjoint_source_area*pi/n, with E the energy of the
|
||||
// particle, n the number of adjoint primary particles of same type that will be
|
||||
// generated during the simulation. Different types of adjoint particles are
|
||||
// generated event after event in order to cover all the type of primaries
|
||||
// and secondaries needed for the simulation. For example if reverse e-
|
||||
// ionisation, brem, photo
|
||||
// electric effect, and compton are considered both adjoint gamma and adjoint
|
||||
// e- will be considered alternatively as adjoint primary. The user can
|
||||
// decide to consider/neglect some type of particle by using the macro commands
|
||||
// /adjoint/ConsiderAsPrimary and
|
||||
/// adjoint/NeglectAsPrimary. If an adjoint primary or its secondary has
|
||||
/// reached the
|
||||
// external surface, in the next event a fwd primary particle equivalent to
|
||||
// the last generated adjoint primary is generated with the same position,
|
||||
// energy but opposite direction and the forward tracking phase starts.
