// -15/01/2007 Creation by L. Desorgher
|
|
// -01/11/2009 Some cleaning and adding of documentation for the first Release in the Geant4 toolkit, L. Desorgher
|
|
// -04/11/2009 Adding the possibility to use user stepping action, L. Desorgher
|
|
// -20/11/2009 Correct the stop of adjoint particles tracking when it reenters the adjoint source.

// Documentation:
|
|
// 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.
