// Class description:
|
|
//
|
|
// Stepping action used in the adjoint simulation.
|
|
// It is responsible to stop the adjoint tracking phase when:
|
|
// a) The adjoint track reaches the external surface.
|
|
// b) The being tracked adjoint dynamic particle get an energy higher than
|
|
// the maximum energy of the external source.
|
|
// c) The adjoint track enters the volume delimited by the adjoint source.
|
|
// In the case a) the info (energy,weight,...) of the adjoint dynamic particle
|
|
// associated to the track when crossing the external source is registered and
|
|
// in the next event a forward primary is generated.
|
|
// In the other cases b) and c) the next generated fwd particle is killed
|
|
// before being tracked and the next tracking of an adjoint particle is
|
|
// started directly.

|
|
// - 04/11/2009 L.Desorgher, added possibility to use user stepping action.
|
|
// - 20/11/2009 L.Desorgher, corrected stop of adjoint particles tracking
|
|
// when reentering the adjoint source.
