Sketch of implementation of different source types within the framework. (a) A fully coherent plane wave, where all particles have the same initial direction and are uniformly sampled over the beam area. (b) The situation of a fully coherent spherical wave where all particles start at the same point and the direction is uniformly sampled. (c) A partially coherent divergent beam with a uniform distribution of the initial position over the source. (d) A partially coherent divergent beam with a Gaussian distribution of the initial positions. The directions in (c) and (d) are sampled according to the beam divergence. |
