对非轴对称(星体)几何结构的环向漂移模在静电极限下的稳定性进行了全面的动力学评估。这个计算是线性化的陀螺动力学方程的综合解，使用了高环向模数不稳定性的最低阶“气球表示”，并带有模型碰撞算符。给出了由温度梯度和/或捕获粒子动力学引起的环向漂移波的结果，该结果使用了作为准轴对称星形器设计工作的一部分产生的三维磁流体动平衡。将这些结果与典型托卡马克情况下的结果进行比较，表明基本趋势是相似的。
A fully kinetic assessment of the stability properties of toroidal drift modes has been obtained for nonaxisymmetric (stellarator) geometry, in the electrostatic limit. This calculation is a comprehensive solution of the linearized gyrokinetic equation, using the lowest-order “ballooning representation” for high toroidal mode number instabilities, with a model collision operator. Results for toroidal drift waves destabilized by temperature gradients and/or trapped particle dynamics are presented, using three-dimensional magnetohydrodynamic equilibria generated as part of a design effort for a quasiaxisymmetric stellarator. Comparisons of these results with those obtained for typical tokamak cases indicate that the basic trends are similar.
