HECTOR: A Code for the Study of High Energy Charged Particles in Axisymmetric Tokamak Plasmas

A code for the study of high energy charged particles resulting primarily from thermonuclear reactions within the confining magnetic fields of  non-circular axisymmetric tokamak plasmas is described. The trajectories of the particles are traced in the (C.O.M) space using a new, fast, and efficient hybrid orbit following scheme based upon the drift equations in the guiding centre approximation and the constants of motion. The code includes the important Coulomb scattering processes of dynamical friction and pitch angle scattering. The code is specifically designed to operate within the experimental environment or in a predictive mode.
