The radiation which appears when an electron beam is injected into a low-density neutral gas in the beam-plasma discharge regime has been studied experimentally. The radiation spectrum can be controlled by modulating the beam velocity at frequencies near the electron plasma frequency. The experimental data permit one to conclude that the most probable mechanism is conversion of the slow waves generated by the beam in the inhomogeneous plasma. It has been shown experimentally that the low-frequency density fluctuations under the conditions of a beam-plasma discharge are of a relaxation nature and are associated with the mechanism for the formation of the discharge plasma. Microwave breakdown of the gas and diffusive loss of charged particles play important roles here. (AIP)
