摘要

通过严格求解导心坐标系下的哈密顿方程，提出了托卡马克装置中离子的真实轨道理论，并利用此理论对国际热核聚变实验堆（ITER）中α离子的真实轨道进行了数值模拟研究，获得了驻点轨道和近期理论预言的半俘获轨道. 根据此真实轨道理论计算了ITER中α离子的直接损失率. 结果发现，与所提出的真实轨道理论相比，以前的回旋平均理论大幅度低估了α离子的直接损失率，两种理论的损失率差值可达14%，对此差异进行了详细的分析并给出了物理上的解释.

Abstract

The full orbit of energetic ion in tokamak is simulated by strictly solving Hamiltonian equations in guiding center coordinate system, and the semi-trapped orbit which is predicted in a recent theoretical research and the stagnation orbit are confirmed by the presently developed full orbit theory. The prompt loss of the energetic particle in international thermonuclear experimental reactor is calculated according to the present full orbit theory. It is found that the prompt loss rate of energetic ion in the full orbit theory can be larger than 14% the result in gyro-averaged theory, and the detailed analysis is carried out and physical understanding is presented in this paper.
