Abstract
The nonlinearly saturated fluctuation level scaling with linear growth rate is presented for two instabilities: the ion temperature gradient instability and the rotationally driven [bold E][times][bold B] instability. In some instances, the plasma self-organizes from plasma turbulence and evolves into a quasicoherent state. In the turbulent state, spectral broadening is observed. The emergence of the semicoherent state is reflected by a narrowing spectral width of the mode with higher linear growth rates and fluctuation levels. The fine structure in the spectral width is resolved and indicates the presence of radial harmonics. The increasing coherence is also supported by a bispectral analysis.
