Abstract :
An orbit-following code is developed to calculate ion beam trajectories in magnetized plasmas. The equation of motion (the Newton´s equation) is solved including the Lorentz force term and Coulomb collisional relaxation term. Furthermore, a new algorithm is introduced by applying a perturbation method regarding the collision term as a small term. The reduction of computation time is suggested.
