EGS-Nova: An Adaptation of EGS in C/C++

Dear EGS4 Users,

Version 0.1.0 of Nova is now available at

There is also now a Nova website at URL Nova is an EGS4-equivalent Monte Carlo radiation transport simulation code in C/C++. Nova is not intended as competition for EGS4, but as a public-domain source of ideas and code snippets for the planned forthcoming C version of EGS5. I make no claim to authorship of the physics content of the code; I simply had some time on my hands and decided to donate part of it as a software engineer. Please get involved and contribute your own ideas for the future of EGS!

Nova ships with XYZNova, a simple Cartesian-coordinate dose deposition application that mimics XYZDOS and is intended for running comparisons between Nova and EGS4. Versions 0.0.1 and 0.0.2 of Nova/XYZNova have been compiled and run without problems on Unix machines, Linux machines, PCs, and Macintoshes. No discrepancies have been found between Nova/XYZNova output and EGS4/XYZDOS output, but further testing is necessary.

Version 0.1.0 of Nova has the resources of the default EGS4 and also supports bremsstrahlung splitting, K-edge fluorescence, accurate bremsstrahlung and pair production angular distributions, and the RANMAR random number generator. Version 0.1.0 also systematizes the application programmer's interface to the Nova transport code library. See

http://www.nemc.org/nova/nova_api.htm

Version 0.2.0 of Nova should be available within six weeks. This version will: a) eliminate the last of the external variables from the implemen- tation (there may actually be a version 0.1.1 for this); b) include the PRESTA electron transport algorithm.

Please feel free to contact me with questions, suggestions, and comments.

Best regards,

Jim Satterthwaite
