A new kinetic-magnetohydrodynamic hybrid simulation model where the gyrokinetic particle-in-cell simulation is applied to both thermal ions and energetic particles is presented. Toroidal Alfvn eigenmodes (TAEs) destabilized by energetic ions in tokamak plasmas are simulated with the new simulation model. Energy channeling from energetic ions to thermal ions through Alfvn eigenmodes (AEs) is demonstrated by the simulation. The distribution function fluctuations and the resonance condition are analyzed for both thermal ions and energetic ions. The strong energy transfer between the particles and the AE and the strong particle transport occur when the following conditions are satisfied at the resonance location in phase space: (1) the poloidal resonance number is close to the poloidal mode number of the AE, (2) the AE has a substantial amplitude, (3) the distribution function has a substantial gradient along the line, where is a conserved variable for the wave-particle interaction. While the distribution function fluctuations for energetic ions are consistent with the resonance condition with the TAEs, the distribution function fluctuations for thermal ions do not satisfy the resonance condition when the bulk plasma beta is 1%. This indicates that the resonance does not play an important role in the interaction between thermal ions and the TAE for the relatively low bulk plasma temperature. On the other hand, when the bulk plasma beta is 4%, the resonance between thermal ions and the TAEs become important leading to Landau damping.

提出了一种新的动力学-磁流体动力学混合模拟模型，其中将旋转动力学粒子在单元中模拟应用于热离子和高能粒子。由托卡马克等离子体中的高能离子不稳定的环形 Alfvn 特征模式 (TAE) 使用新的模拟模型进行模拟。模拟证明了通过 Alfvn 特征模式 (AE) 从高能离子到热离子的能量通道。分析了热离子和高能离子的分布函数波动和共振条件。当相空间共振位置满足以下条件时，粒子与AE之间的强能量传递和强粒子输运发生：（1）极向共振数接近AE的极向模式数，（2 ) AE 具有相当大的振幅，线，其中是波粒相互作用的守恒变量。虽然高能离子的分布函数波动与 TAE 的共振条件一​​致，但当体等离子体 beta 为 1% 时，热离子的分布函数波动不满足共振条件。这表明对于相对较低的体等离子体温度，共振在热离子和 TAE 之间的相互作用中没有发挥重要作用。另一方面，当体等离子体 beta 为 4% 时，热离子和 TAE 之间的共振变得重要，导致朗道阻尼。
