Abstract

1,025,878. Travelling wave tubes. VARIAN ASSOCIATES. June 14, 1963 [June 25, 1962], No. 33635/65. Divided out of 1,025,876. Heading H1D. A travelling wave tube having a cathode, an anode and a collector electrode comprises a tubular body portion 17 positioned between the anode and the collector electrode, a tubular slow-wave structure 18 positioned within the body portion, and rods 19 supporting the slowwave structure coaxially within and spaced from the body portion, the inside surface of the tubular body portion being provided with elongated, longitudinally extending grooves 21 to receive the support rods in such a manner that good thermal contact is made between the slow-wave structure, the support rods and the body portion for conducting heat from the slow-wave structure. The outside surface of the slow-wave structure is also provided with grooves 22 to receive the support rods. The outside of the body portion is fluid cooled in a manner described in Specification 1,025,876.
