热电子、双离子成分对离子漂移迴旋不稳定性的影响

THE EFFECT OF HOT ELECTRON AND DOUBLE ION COMPONENT ON DRIFT-CYCLOTRON-INSTABILITY

分析了热电子、温(热)离子成分对离子漂移迴旋不稳定性的影响。给出了临界稳定热电子成分值α与温(热)离子成分值、离子温度比和离子抗磁漂移速度的关系;讨论了热电子、温(热),冷离子成分对不稳定性各谐频分支的影响;分析了热电子成分稳定作用的物理机制。

In this paper,the effect of hot electron and warm(hot) ion components on the drift-cyclotron-instability(DCI)is studied. Some relations are given as follows:The dependence of marginal stable hot electron value on warm (hot) ion value; the temperature ratio of warm (hot) ion to cold ion; and ion diamagnetic drift velocity. The influences of hot electron and warm (hot) ion on the different DCI harmonic branchs are discussed. The stable mechanism of hot electron is analysed for the first time.
