摘要：
An analytical investigation of modulational and filamentation instabilities of an upper-hybrid wave due to electron-acoustic density perturbations in a two-electron temperature plasma has been made. A hydrodynamical model of the plasma is used. Nonlinear dispersion relation and growth rates are calculated. As an application of the investigation, the variation of the growth rate with the concentration ratio of hot to cold electrons, temperature ratio (T(c)/T(h)) and magnetic field for typical parameters of laser-plasma interaction in ELMO bumpy torus is studied and is shown graphically.
