Abstract
The GNET code is used to study α particle confinement with energy diffusion and pitch angle scattering in helical plasmas based on the Monte Carlo technique. The dependency of the accuracy of the distribution function on the number of test particles is studied. It is found that, as the number of test particles is increased, the shape of the velocity space distribution becomes smooth and the scattering of the energy loss fraction becomes small and converges to 5.06%.
