The Collimator_linear Component

A simple analytical Soller collimator (with triangular transmission).

Identification

Description

Soller collimator with rectangular opening and specified length. The
transmission function is an average and does not utilize knowledge of the
actual neutron trajectory. A zero divergence disables collimation (then the
component works as a double slit).

Example: Collimator_linear(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, length=0.25, divergence=40,transmission=0.7)

Input parameters

Parameters in boldface are required; the others are optional.
