Low-frequency instability in weakly ionized current-carrying magnetized plasmas. I. Experiments on instability behaviour

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

Low-frequency drift wave-type instability of weakly ionized, weakly magnetized plasma in a DC discharge in argon is studied experimentally. The instability exists in the intermediate region Omega ci approximately nu i, rho i approximately R between the conditions defining magnetization and unmagnetization of the ion plasma component ( Omega ci and rho i are the ion gyrofrequency and gyroradius, nu i is the ion-neutral collision frequency and R is the radius of the plasma column). The observations pertain to the appearance of the instability as a threshold effect and its dispersion properties. The behaviour of the instability is interpreted in relationship with the variation of the ambipolar field and its anomalously enhanced values. The effect of the longitudinal electric field sustaining the discharge is also discussed.

アルゴン中の直流放電における弱電離・弱磁化プラズマのドリフト波型不安定性を実験的に研究した。この不安定性は、イオンプラズマ成分の磁化および非磁化の条件を定義する中間領域Ω_ci≒ν_i、ρ_i≒Rに存在する(Ω_ciおよびρ_iはイオンジャイロ周波数およびイオンジャイロ半径、ν_iはイオン-中性粒子衝突周波数、Rはプラズマ柱の半径である)。観測結果は、閾値効果としての不安定性の出現とその分散特性に関するものである。この不安定性の挙動は、両極性電界の変動およびその異常増大と関連づけて解釈された。放電を維持する縦方向電界の影響についても議論した。
