The Source_flat_lambda Component

Neutron source with flat wavelength spectrum and arbitrary flux.

Identification

Description

The 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.
OBSOLETE: rather use sources/Source_simple

Example: Source_flat_lambda(radius=0.1, dist=2, xw=.1, yh=.1,
          lambda_0=2.36, d_lambda=.3)
WARNING: This is an obsolete Component.Please avoid usage whenever possible.
