Abstract Text:
A full kinetic code based on Boris scheme is developed to study particle dynamics in high frequency waves in tokamaks. With magnetic field applied to tokamaks, the code shows good properties in conserving energy and magnetic moment. The toroidal precession frequency is measured, which is basically consist with guiding center simulation, and the little difference is demonstrated to be caused by approximate field model. Ware-pinch due to toroidal electric field and neo-classical polarization drift due to time-dependent poloidal field is observed and compared with theory prediction.
