Low-frequency instability in weakly ionized current-carrying magnetized plasmas. II. Behaviour in high-frequency wave field

Z Kissovski, A Shivarova, E Tatarova1994年Plasma Physics and Controlled FusionIF 2.2出版社

The effect of the Trivelpiece-Gould mode on the behaviour of a low-frequency drift instability in a weakly ionized magnetized plasma is studied experimentally in a DC argon discharge. The ions are weakly magnetized, i.e. Omega ci approximately nu i, rho i approximately R ( Omega ci and rho i are the ion gyrofrequency and gyroradius, nu i is the ion-neutral collision frequency and R is the plasma radius). With increasing amplitude of the high-frequency field, the frequency and the amplitude of the instability decrease. Since the anomalously enhanced ambipolar field is considered as a very important factor in the mechanism driving the instability, special attention is paid to its variation with increasing high-frequency power. The nonlinear mechanisms of the dynamical control of the instability are discussed.

Trivelpiece-Gouldモードが弱磁化プラズマ中の低周波ドリフト不安定性の挙動に及ぼす影響を、DCアルゴン放電中で実験的に研究した。イオンは弱磁化されており、すなわちΩ_ci ≈ ν_i、ρ_i ≈ Rである(ここでΩ_ciとρ_iはそれぞれイオンジャイロ周波数とジャイロ半径、ν_iはイオン-中性粒子衝突周波数、Rはプラズマ半径である)。高周波電場の振幅を増加させると、不安定性の周波数と振幅は減少する。異常に増強された両極性電場は、不安定性を駆動する機構において非常に重要な因子であると考えられるため、その高周波パワーの増加に伴う変化に特に注目した。不安定性の動的制御における非線形機構について議論する。
