Abstract :
LANL has developed a new vane loaded waveguide RF structure for a sheet beam TWT. The goal was to create a new class of wideband RF structures that allow simple mechanical fabrication and have geometry suitable for interaction with sheet electron beams. LANL has developed an RF structure using planar geometry for simple EDM machining at 94GHz. Structure gain was demonstrated with a 2A pencil beam
