As part of a project to study backscatter of kilovoltage electrons and positrons from various materials, a general purpose EGSnrc user-code was developed for simulating backscatter using the state-of-the-art Monte Carlo code. It scores backscatter coefficients, backscatter angular distributions and backscatter energy spectra for a variety of geometries. The results of this work are published in two papers.

For more information and instructions on how to install and use the code, see
Manual of backscatter_clrp: An EGSnrc user-code for backscatter calculations
The entire user_code distribution plus pdfs of the two papers are available as a tar file (4.4 Mbyte)
and a gziped version is available here (1.7 Mbyte)
In order to run this EGSnrc user-code, one must first install the EGSnrc system which is available at the distribution site for the EGSnrc Monte Carlo system. This system runs on Unix, Linux and Windows operating systems.
