PATENT APPLICATION of ARTHUR KARP for SLOW-WAVE CIRCUIT FOR TRAVELING-WAVE TUBES ABSTRACT In a traveling-wave tube for very high frequencies the slow-wave circuit is formed of four metal combs having teeth pointed toward the electron beam. The combs are arranged in two pairs. The teeth of the two combs in each pair extend inward from opposite sides of the beam and are axially aligned to form the electrical equivalent of a half- wave bar or ladder structure. They may or may not be joined at the tips because those are low-current points. The teeth of one pair are at right angles to those of the other pair and are displaced axially to interleave with them. Each comb is preferably made from A single piece of copper to provide better dimensional precision, low circuit loss, mechanical durability and high thermal capability. 2rbn31379 - 1 - 79-16
