Description

An experimental demonstration of a strong enhancement of the interaction efficiency in a high power relativistic backward wave oscillators when plasma is injected is presented. Plasma injection enhances the interaction efficiency by a factor of up to 8 to a value of about 40%. Overdriving the device with plasma above a critical density quenches the interaction. It is anticipated that plasma injection may prove beneficial in other high power microwave and millimeter devices such as free electron lasers and gyrotrons. The enhanced interaction is attributed to induced scattering of the electromagnetic radiation of electrons in an electrostatic field produced by the background plasma and a beam space charge wave in the corrugated interaction region
