Electromagnetic semi-local kinetic analysis of the electron temperature gradient mode in tokamaks

A. Hirose1991年Nuclear FusionIF 3出版社

Electromagnetic (finite beta) effects on the toroidal electron temperature gradient mode have been investigated in terms of an electromagnetic semi-local kinetic dispersion relation. For this mode, finite beta is destabilizing, in contrast to the ion temperature gradient mode. However, a relatively steep temperature gradient, T = LT/R < 0.15, is required for the instability. The most unstable mode satisfies ω ≃ ωTe (the electron transit mode).

電磁(有限ベータ)効果がトロイダル電子温度勾配モードに及ぼす影響を、電磁的半局所運動論的分散関係に基づいて調べた。このモードに対して、有限ベータは不安定化をもたらすが、これはイオン温度勾配モードとは対照的である。しかしながら、不安定性が生じるためには、比較的急峻な温度勾配、すなわちT = LT/R < 0.15が必要である。最も不安定なモードは、ω ≃ ωTe(電子トランジットモード)を満たす。
