Stationary Spectrum of Strong Turbulence in Magnetized Nonuniform Plasma
Abstract
A stationary spectrum in the frequency range much below the ion cyclotron frequency is obtained for a strongly turbulent nonuniform plasma. The ω-integrated k spectrum is given by k1.8(1+k2)-2.2, while the width of the frequency spectrum is proportional to k3(1+k2)-1, where k is normalized by csωci. The result compares well with the recently observed spectrum in the ATC tokamak.
