Abstract
By solving the hydrodynamic equations for the parametric instability including modecoupling terms, we predict the saturation level and turbulent spectrum for the oscillating two-stream instability. Coupling the electron distribution function to the spectrum with the quasilinear diffusion coefficient gives the heating rate and high-energy tail formation. These predictions agree with the results of particle simulations.Keywords
