Abstract
We study the α-particle confinement including the collisions with various plasma species such as electron, deuterium, tritium, and high-energy α-particle. GNET code (Global NEoclassical Transport) is improved to take into account the nonlinear collision effect in a heliotron fusion reactor based on the LHD configurations. We analyze the real and velocity space distributions and the energy and particle loss rate changing the background plasma parameters, and verify the effects of collision with high-energy particles on the α-particle confinement.
