FAFNER2 : 3-D "flux coordinate" neutral beam injection code using Monte Carlo methods
The FAFNER2 Monte Carlo code simulates the injection of fast neutral particles into a 3-dimensional toroidal plasma and the paths of the resulting fast ions until they are either lost to the system or fully thermalised. A comprehensive model for the neutral beam injection system is included. The guiding centre equations for the fast ions are solved in Boozer flux coordinates. This is the main difference from the original FAFNER1 version. The program is written especially for use on CRAY computers; in particular, the numerical treatment of the fast ion interaction with the background plasma, which used the majority of the computer time, has been vectorised. Results obtained with the FAFNER2 code are compared with those from FAFNER1.
