Abstract :
LANL has developed a new vane loaded waveguide RF structure for a sheet electron beam TWT. It is common for all high gain TWT amplifiers to require a circuit sever to prevent oscillations. We have developed a preliminary sever design in our vane loaded waveguide RF structure. A scale model of the RF structure was used at 10GHz to test several sever geometries. The structure and sever were simulated using HFSS
