Abstract : A travelling-wave-tube has a vacuum housing that includes the helix rf circuitry. The helix conductor is intertwined with and hermetically sealed to the insulating material comprising the vacuum housing. Thus, portions of the helix interact with the electron beam in the center of the vacuum housing while other portions are in contact with the atmosphere, thus cooling the helix and permitting the tube to operate at higher average powers.
