Low-frequency instabilities of the high-frequency skin layer in a plasma with non-uniform parameters

V.P. Sidorov, V.S. Tsypin, L.A. Utkina1970年被引用 1Nuclear FusionIF 3出版社

The authors investigate low-frequency instabilities caused by non-uniformity of the macroscopic parameters of a plasma located in a constant magnetic and a high-frequency (HF) electric field. In section 2 the instabilities of a completely ionized plasma are studied with allowance for Coulomb collisions. It is shown that the effect of "induced" longitudinal friction significantly changes the spectrum of natural oscillations of the drift-dissipative type. In section 3 the authors consider the influence of the HF field on hydrodynamic drift-temperature, drift-cyclotron and centrifugal instabilities. The HF field is found to have both a stabilizing and a destabilizing influence.

著者らは、一定の磁場および高周波(HF)電場中に置かれたプラズマの巨視的パラメータの非一様性によって引き起こされる低周波不安定性を調査する。第2節では、完全電離プラズマの不安定性をクーロン衝突を考慮して研究する。「誘起された」縦方向摩擦の効果が、ドリフト・散逸型の自然振動のスペクトルを著しく変化させることが示される。第3節では、高周波電場が流体力学的ドリフト温度不安定性、ドリフト・サイクロトロン不安定性、および遠心不安定性に及ぼす影響を考察する。高周波電場は安定化効果と不安定化効果の両方を有することが見出される。
