Neoclassical Transport of Energetic Alpha Particle

POSTER

Abstract

A simulation of neoclassical transport for energetic alpha particle is carried out using the gyrokinetic particle code GTC. A linearized Coulomb collision operator is implemented, including slowing down, pitch angel scattering and energy scattering term. In addition, source and sink are carefully treated in the simulation to ensure conservation properties. Simulation results show good agreement with analytic results on radial particle and heat diffusivity, as well as bootstrap current.
