BEAMnrc

BEAMnrc is a general purpose Monte Carlo simulation system for modelling radiotherapy sources which is based on the EGSnrc code system for modelling coupled electron and photon transport. BEAMnrc is the current version of BEAM (no longer supported, based on EGS4). Unlike the earlier versions which only worked on a selection of Linux and Unix systems, BEAMnrc now works on Linux, Unix, Windows, and possibly Mac OSX.

The BEAMnrc system has been described extensively in the literature and many of NRC's papers about BEAM and BEAMnrc are available under Publications. There are many papers written by others who have used the BEAMnrc or BEAM system and these are included in a list of BEAM related papers (last updated in 2002). You may also want to see the extensive BEAMnrc online documentation.

BEAM was developed originally as part of the OMEGA project which was a collaboration between the National Research Council Canada and Rock Mackie's group at the University of Wisconsin in Madison.

BEAMnrc works as a user code for EGSnrc, the latest version of the renowned EGS code system which features much improved transport physics and the ability to work on all major operating systems.

The BEAMnrc system is available for download for free to non-commercial users. Please read the system requirements and the license agreement under which the code is distributed before downloading. It is strongly recommended that you take a BEAM course to get trained on how to use the code effectively. Once someone has taken a course, we try to support their use of the code, but we cannot support those who try to use the code without taking a course.
