Abstract
Results from a study of a relativistic X-Band backward-wave oscillator (RBWO) with 3-GW output microwave power are presented. The RBWO was d riven by the high-current electron accelerator SINUS-7. The dependence of radiated microwave pulse duration on microwave power was obtained, Pulse shortening occurring at the higher power levels is probably att ributable to explosive electron emission from the slow wave structure (SWS), An increase in the cross section of the electrodynamic structur e seems to be a way to increase the microwave pulse duration. Experime ntal results from a moderately oversized X-band RBWO using a resonance reflector are described. This tube can be operated,vith a low externa l magnetic field.
