Abstract

A tunable backward-wave oscillator (BWO) gyrotron is currently being operated at MIT which is a prototype for a FEL driver at high frequency. Novel features of this design, are the overmoded TE12 cylindrical cavity, a wide band moth-eye window, and the use of a Pierce-wiggler gun. The design objectives are voltage tuning from 130-140 GHz with 10 kW output power. The interaction region is 10λο long where λο is the free space wave length. A linear 2° uptaper is used to maintain mode purity and a broadband motheye window is used for maximum transmission.
