MUTUALLY INTERACTING INSTABILITIES IN THE MAGNETOSPHERE.

Abstract

The mutual interaction of a drift wave instability and a high-frequency instability is studied. When both instabilities are present in a plasma, the usual dispersion relation for the drift wave is modified by terms involving the wave intensity of the high-frequency instability; generally, damping results. An example is worked out: the Mikhailovskii-Rudakov drift Alfven mode, in the presence of an electron cyclotron instability. For auroral magnetospheric parameters, high-frequency damping is comparable to the usual linear growth rate for the drift instability. (Author)
