Abstract Collector-Output for Hollow Beam Electron Tubes In a microwave electron tube such as a gyrotron, a hollow beam of electrons passes thru the inter- action cavity into an output waveguide carrying the generated energy in a mode with circular electric fields. According to the invention, the beam is caused to expand, passing thru a gap in the wave- guide to be collected on a larger, surrounding col- lector. The collector energy is thus reduced. The wave energy jumps the gap and continues down the waveguide. Wave energy leaking into the collector may be absorbed by lossy material therein or be carried off by waveguides to external loads.
