本文开发了一种适用于研究射频加热和电流驱动非线性现象的环面粒子池（PIC）代码，并通过一系列环面几何场解算器和单粒子运动的保真度测试进行了验证，仿真结果与分析预测吻合良好。然后通过圆柱形几何中的线性低混合波和离子伯恩斯坦波理论的集成基准测试来证明射频能力，其中分析结果很容易获得。仿真得到的频率和模态结构与理论预测吻合较好。
A toroidal particle-in-cell (PIC) code, suitable for investigating nonlinear phenomena in radio frequency (RF) heating and current drive, is developed and verified thereafter through a series of fidelity tests for field solvers and single particle motions in toroidal geometry, where simulation results show good coincidence with analytical prediction. The RF capability is then demonstrated through the integrated benchmarks with linear lower hybrid wave and ion Bernstein wave theory in cylindrical geometry, where the analytic result is easily available. The frequency and mode structure in the simulations agree well with the theoretical prediction.
