説明
Dispersion characteristics and numerical results are presented of the crossfield-current-driven electrostatic instabilities in an inhomogeneous magnetoplasma. By use of a two-fluid hydrodynamic model in a cylindrical coordinate involving the effects of finite temperature and density inhomogeneity, we present the corresponding dispersion relation and show that, in the low-frequency range ω2<<ωci2 (ωci: ion-cyclotron frequency), there exists an instability termed as the modified ion-cyclotron instability. These wave characteristics are clarified in some parameter spaces. Apart from this, some numerical nesuls are also presented of the lower-hybrid instability and the ion-cyclotron harmonic instability, the latter being obtained with a kinetic model in an inhomogeneous hot plasma. The comparison of these results with the experiment is also made especially for the modified ion-cyclotron mode, and it is found that the experimental results are in qualitative agreement with the theoretical prediction.
