摘      要：Fusion born α particle confinement is one of the most important issues in burning plasmas,such as ITER and ***,it is extremely complex due to the nonequilibrium characteristics,and multiple temporal and spatial scales coupling with background plasma.A numerical code using particle orbit tracing method(PTC)has been developed to study energetic particle confinement in tokamak *** full orbit and drift orbit solvers are implemented to analyze the Larmor radius effects on α particle *** elastic collisions between alpha particles and thermal plasma are calculated by a Monte Carlo method.A triangle mesh in poloidal section is generated for electromagnetic fields *** between PTC and ORBIT has been accomplished for *** CFETR burning plasmas,PTC code is used for α particle source and slowing down process calculation in 2D *** future work,3D field like toroidal field ripples,Alfven and magnetohydrodynamics instabilities perturbation inducing α particle transport will be analyzed.
