Diamond, P H; Myra, J R

A renormalized, energy conserving theory of low frequency, finite Larmor radius turbulence is applied to the determination of the nonlinear electron response to the low-hybrid-drift instability. The theory predicts saturation of the short wavelength modes by a Compton scattering induced cascade to long wavelengths. The saturation amplitude is in reasonable agreement with the turbulence level needed for suppression of the drift cyclotron mode.
