X-ray compound refractive lens (CRL) with an elliptic profile
Identification
- Site:
- Author: Jana Baltser and Erik Knudsen
- Origin: NBI
- Date: August 2010
Description
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
