摘要:

诸如离子回旋共振加热(ICRH)的离子回旋共振能量化(ICRE)被广泛应用于磁约束聚变和大功率电推进。由于 ICRE 涉及回旋共振过程,因此需要动力学模型。传统的粒子模拟(PIC)和求解 Boltzmann 方程都需要巨大的计算量和内存。结合绝热电子和 PIC 离子的混合模拟既能大幅减少计算量,又能包含回旋共振效应。在绝热电子近似下,我们开发了一个二维(r,z)混合电磁(EM)PIC-MCC(蒙特卡罗碰撞)模拟程序,命名为 HYPIC。HYPIC 的优势在于以较小的计算量包含了离子动力学效应、静电(ES)和 EM 效应,以及离子和电子的碰撞效应。HYPIC 程序能够快速模拟直线装置中的天线-等离子体相互作用以及离子回旋共振能量化和/或离子回旋共振加热过程,例如大功率电推进、磁镜和场反位形(FRC)等。

英文摘要:

Ion cyclotron resonance energization (ICRE) such as ion cyclotron resonance heating (ICRH) is widely applied to magnetic confinement fusion and high-power electric propulsion. Since ICRE involves cyclotron resonance processes, a kinetic model is required. Both conventional particle-in-cell (PIC) simulations and solving the Boltzmann equation require enormous computation and memory. The hybrid simulation incorporating of adiabatic electrons and PIC ions allows both a substantial reduction in computation and the inclusion of cyclotron resonance effects. Under the adiabatic electron approximation, we have developed a two-dimensional (r,z) hybrid electromagnetic (EM) PIC-MCC (Monte-Carlo collision) simulation program, named HYPIC. The advantages of HYPIC are the inclusion of ion kinetic effects, electrostatic (ES) and EM effects, and collisional effects of ions and electrons, with a small computation. The HYPIC program is able to fast simulate the antenna-plasma interactions and the ion cyclotron resonance energization and/or ion cyclotron resonance heating processes in linear devices, such as high-power electric propulsion, magnetic mirror, and field-reversed-configuration (FRC), etc.
