Dispersion properties of an inhomogeneous turbulent magnetoactive plasma

A.K. Nekrasov1976年被引用 4Nuclear FusionIF 3出版社

The author has obtained the dispersion equation for an inhomogeneous turbulent magnetoactive plasma. The frequencies and wave vectors of oscillations are assumed to be arbitrary. The effect of ion-cyclotron oscillations on flute oscillations is considered. It is shown that when the amplitude is sufficiently large, cyclotron oscillations determine the flute oscillation frequency, which is equal in order of magnitude to the ratio between the electric drift velocity and the characteristic length of the inhomogeneity of the plasma. The flute oscillations become stable (unstable) in the field of cyclotron Oscil lations of a wavelength greater (shorter) than the ion Larmor radius.

著者は、不均一な磁化プラズマに対する分散方程式を得た。振動の周波数と波数ベクトルは任意であると仮定される。フルート振動に対するイオンサイクロトロン振動の影響が考察される。振幅が十分に大きい場合、サイクロトロン振動がフルート振動の周波数を決定し、その周波数は電気ドリフト速度とプラズマの不均一性の特性長との比のオーダーに等しいことが示される。フルート振動は、イオンラーマー半径より大きい(小さい)波長のサイクロトロン振動の場において、安定(不安定)になる。
