Universal instability in a potassium plasma

N. S. Buchelnikova1964年被引用 26Nuclear FusionIF 3出版社

We have discovered oscillations in a highly ionized potassium plasma of non-uniform density in a magnetic field of an intensity of 600–1600 Oe and observed three or four harmonics with a fundamental frequency of ∼5–10kHz.The oscillations represent an azimuthal wave having a component along the magnetic field. Oscillation frequency is inversely proportional to the magnetic field strength. Oscillations are observed both in a dilute (n = 108–109 cm–3), and in a dense plasma (n = 1010–5 × 1011cm–3). Oscillation excitation is not related to the presence of electric layers on the plasma boundary.It is shown that the observed oscillations are the development of "universal" instability of a plasma of non-uniform density.

我々は、不均一密度の高度に電離したカリウムプラズマ中で、600–1600 Oeの強度の磁場中において振動を発見し、基本周波数が∼5–10kHzの3つまたは4つの高調波を観測した。この振動は、磁場に沿った成分を有する方位角波を表す。振動周波数は磁場強度に反比例する。振動は、希薄プラズマ(n = 108–109 cm–3)と高密度プラズマ(n = 1010–5 × 1011cm–3)の両方で観測される。振動励起は、プラズマ境界上の電荷層の存在とは関係がない。観測された振動は、不均一密度プラズマの「普遍的」不安定性の発現であることが示される。
