FAFNER - A FULLY 3-D NEUTRAL BEAM INJECTION CODE USING MONTE CARLO METHODS
A computer code is described which models the injection of fast neutral particles into 3-dimensional toroidal plasmas and follows the paths of the resulting fast ions until they are either lost to the system or fully thermalized. A comprehensive model for the neutral beam injection system is included. The code is written specially for use on the CRAY-1 computer: in particular, the modular nature of the program should enable the most time consuming sections of the program to be vectorized for each particular experiment to be modelled. The effects of plasma contamination by possible injection of impurities, such as oxygen, with the beams are also included. The code may also be readily adapted to plasmas for which a 1- or 2-dimensional description is adequate. It has also been constructed with a view to ready coupling with a transport or equilibrium code.
