Time-Resolved Light-Scattering Measurements of the Spectrum of Turbulence within a High- β Collisionless Shock Wave

M. Keilhacker, K.‐H. Steuer

Abstract

Strong current-driven turbulence is observed in high-$\ensuremath{\beta}$ collisionless shock waves under ${T}_{e}\ensuremath{\sim}{T}_{i}$ and ${v}_{d}\ensuremath{\ll}{v}_{e}$ conditions. The level and the frequency and wave-number spectra of this turbulence are measured by scattering light from the shock. The turbulence is probably due to an electron-cyclotron drift instability.
