X-ray compound refractive lens (CRL) with an elliptic profile
Author: Jana Baltser and Erik Knudsen
Origin: NBI
Date: August 2010
A simple X-ray compound refractive lens (CRL) with an elliptic profile simulates the photons’ movement on passing through it. Attenuation coefficient mu is taken from the NIST database and Be.txt
Parameters in boldface are required; the others are optional.
