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