Observation of magnetic-drift instability in a system with large β

We have observed and investigated the low-frequency magnetic-drift instability in a θ-pinch plasma with β ^ 1. Its appearance is connected with the onset of the mechanism of thermalization of the accelerated-electron energy. The oscillation amplitude is comparable with the magnitude of the main magnetic field.
