Installing BEAMnrc With EGSnrc on a Linux Cluster
EGSnrc (Electron Gamma Shower) is "a package for the Monte Carlo simulation of coupled electron-photon transport. Its current energy range of applicability is considered to be 1 keV to 10 GeV". The previous instructions for installing it remain the same. EGSnrc has an additional program, 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 requires EGSnrc to be installed. Once this is done download the latest version of BEAMnrc; put the tarballs in a sensible place e.g.,
Ensure that install_beam is executable;
chmod u+x install_beam.
Export the EGSnrc environment variables. BEAMnrc will not install without these. Make note of the trailing slash; they are important, sometimes.
Now you're ready to install BEAMnrc:
It will complete with the following notification:
The OMEGA/BEAM basic installation is finished. Every user who wants to use the system must now run the script /home/egsnrc/scripts/finalize_beam_foruser This will copy example .module files into the user's EGS_HOME/beamnrc/spec_modules directory and compile DOSXYZnrc on the user's area.
Ensure that you make the files readable.
chmod a+r /home/egsnrc/ -R
