摘要： 我们提出了一种用于等离子体中微不稳定性研究的辛电磁全动能粒子-网格模拟，使用的是Cyclone基础案例[Dimits等人，等离子体物理 7，969 (2000)]中的参数。 结果表明，包括离子温度梯度(ITG)、捕获电子模(TEM)和动能球形模(KBM)在内的不稳定模式的增长率与之前动力学模型得到的结果一致。 此外，还再现了ITG的\b{eta}稳定化。 分析还表明，离子-电子质量比和数值光速对最不稳定的模式增长率的影响可以忽略不计。 这表明，当在相关时空尺度上研究漂移波不稳定性物理时，全动能方法具有降低计算成本的潜力。 显示英文摘要

摘要： We present a symplectic electromagnetic fully-kinetic particle-in-cell simulation of microinstabilities in plasma, using parameters from the Cyclone Base Case [Dimits, et al., Physics of Plasmas 7, 969 (2000)]. The results show that the growth rates of unstable modes, including ion temperature gradient (ITG), trapped electron mode (TEM), and kinetic ballooning mode (KBM), are consistent with those obtained from previous gyrokinetic models. Additionally, the \b{eta}-stabilization of the ITG is reproduced. The analysis also reveals that the impact of the ion-electron mass ratio and the numerical speed of light on the growth rate of the most unstable modes is minimal. This suggests that the fully kinetic method offers a potential for reduced computational cost when investigating the physics of drift wave instabilities at relevant space-time scales.
