| 46 | // This class represents the PrimaryGeneratorAction that is used during the entire adjoint simulation. |
---|
| 47 | // It uses the class G4AdjointPrimaryGenerator to generate randomly adjoint primary particles on a user selected |
---|
| 48 | // adjoint source (External surface of a volume or Sphere). |
---|
| 49 | // The spectrum of the primary adjoint particles is set as 1/E with user defined max and min energy. |
---|
| 50 | // 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 |
---|
| 51 | // particle, n the number of adjoint primary particles of same type that will be generated during the simulation. |
---|
| 52 | // Different types of adjoint particles are generated event after event in order |
---|
| 53 | // to cover all the type of primaries and secondaries needed for the simulation. For example if reverse e- ionisation, brem, photo electric effect, and |
---|
| 54 | // compton are considered both adjoint gamma and adjoint e- will be considered alternatively as adjoint primary. |
---|
| 55 | // The user can decide to consider/neglect some type of particle by using the macro |
---|
| 56 | // commands /adjoint/ConsiderAsPrimary and /adjoint/NeglectAsPrimary. If an adjoint primary or its secondary has reached the external surface, |
---|
| 57 | // 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 |
---|
| 58 | // and the forward tracking phase starts. |
