Abstract

It is found experimentally that the interaction of plasma flows propagating in opposite directions across a magnetic field is accompanied by periodic local bursts of intense optical and soft X-ray emission. It is shown that periodic variations in the emission intensity from the interaction region are related to the excitation of steady-state self-oscillations in the plasma. By varying the frequency and amplitude of these oscillations, it is possible to satisfy the resonance conditions at certain characteristic plasma frequencies.
