Source_simple
ComponentThe routine is a circular neutron source, which aims at a square target centered at the beam (in order to improve MC-acceptance rate). The angular divergence is then given by the dimensions of the target. The neutron energy is uniformly distributed between E0-dE and E0+dE. This component replaces Source_flat, Source_flat_lambda, Source_flux and Source_flux_lambda. Example: Source_simple(radius=0.1, dist=2, xw=.1, yh=.1, E0=14, dE=2)
