论文摘要
使用理论分析和陀螺仪仿真（包括综合碰撞模型）在磁化板平面物中研究了由电子温度梯度驱动的碰撞微功能模式的不稳定机制。微关系的必要不稳定机制是由于速度依赖性电子 - 离子碰撞引起的时间依赖的热力和惯性力，因此磁场后面的平行电感电场的滞后。碰撞效应的定量测量使我们能够确定针对碰撞性的不稳定制度，并揭示了碰撞微呈现模式与现有的环形实验的相关性。非线性模拟表明，微功能模式不会随着磁能的爆炸性释放和转换而驱动磁性重新连接。
The destabilization mechanism of the collisional microtearing mode driven by an electron temperature gradient is studied using theoretical analyses and gyrokinetic simulations including a comprehensive collision model, in magnetized slab plasmas. The essential destabilization mechanism of the microtearing mode is the lag of the parallel inductive electric field behind the magnetic field owing to the time-dependent thermal force and inertia force induced by the velocity-dependent electron--ion collisions. Quantitative measurements of the collision effects enable us to identify the unstable regime against collisionality and reveal the relevance of the collisional microtearing mode with existing toroidal experiments. A nonlinear simulation demonstrates that the microtearing mode does not drive magnetic reconnection with the explosive release and conversion of the magnetic energy.
