等离子体电流反向平衡位形中带电粒子运动的数值模拟研究
Numerical Simulation Research on Transport of Charged Particle in Plasma with Current-reversal Equilibrium Configuration
摘要
Abstract
The equilibrium configuration and magnetic distribution were achieved by numerically solving Grad‐Shafranov equation w hen the total current exceeded zero in the AC operation experiment on CT‐6B .Considering the motion equation of particles in magnetic field , trajectories of deuterium ions in this equilibrium configuration were simulated ,and also ,the ratios and positions of deuterium ions loss were statistically calculated .The results indicate that the equilibrium configuration is the current‐reversal equilibrium configurations with two oppositely flowing current components on the high‐field side and low‐field side w hen the total current exceeds zero ,magnetic islands exist at high‐field side and low‐field side both ,and current value is extreme value near the magnetic island . T he particles in high‐field side lose barely , but loss happens w hen radial location is much high at low‐field side and the loss rate increases as it reaches to boundary .Basically ,positions of loss locate beneath equatorial plane and loss reaches the extreme value at the very bottom .Trajectory of deuterium ions converts from pass‐ing particle trajectory to lost particle trajectory firstly ,and further ,to trapped particle trajectory w hen the initial angle becomes large .关键词
