A. D. Bolshakova, A. Yu. Chirkov, V. I. Khvesyuk

摘要:

驱动离子和电子温度梯度(ITG和ETG不稳定性)的静电漂移不稳定性被认为是从逆离子热gyroradius的电子热gyroradius的垂直波数值的范围。分析是在当地的动力学方法的框架。不稳定参数的标度律。这些标度律可作为计算具有纯极向磁场拓扑结构的磁阱中无碰撞等离子体输运率的基础。

英文摘要:

Electrostatic drift instabilities driven by ion and electron temperature gradients (ITG and ETG instabilities) are considered for the ranges of perpendicular wave number values from the inverse ion thermal gyroradius up to the electron thermal gyroradius. The analysis is carried out in the framework of the local kinetic approach. Scaling laws for instability parameters are presented. These scaling laws can be used as a basis of collisionless plasma transport rates in magnetic traps with purely poloidal magnetic field topology.
