Source_flux_lambda
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 wavelength is uniformly distributed between lambda_0 - d_lambda and lambda_0 + d_lambda. The source flux is specified in neutrons per steradian per square cm per AAngstroem. Example: Source_flux_lambda(radius=0.1, dist=2, xw=.1, yh=.1, lambda_0=2.36, d_lambda=.3, flux=1e13)
