Abstract
A collector of a traveling wave tube in which a larger quantity of loss ceramic members are arranged between an outer collector enclosure and an outer surface of a collector electrode for increasing high frequency loss to prevent RF leakage from the collector lead wire. The collector includes a collector electrode 2, heat conductive columnar ceramic elements 3, an outer collector enclosure 4 for maintaining vacuum and loss ceramic members 5 arranged between the outer surface of the collector electrode 2 and the inner surface of the outer collector enclosure 4.
Claims14
A collector of an internal insulation type of a traveling wave tube having a structure in which a collector electrode is supported by a plurality of heat conductive columnar ceramic elements arranged between the collector electrode and an outer enclosure of the collector, wherein
- a loss ceramic member is arranged between the outer surface of the collector electrode and the inner surface of the outer enclosure of the collector.
A collector of an internal insulation type of a traveling wave tube having a structure in which a collector electrode is supported by a plurality of heat conductive columnar ceramic elements arranged between the collector electrode and an outer enclosure of the collector, wherein
- insulating loss ceramic members displaying high frequency loss are arranged between the outer surface of said collector electrode not illuminated with an electron beam and a surface of said outer enclosure contacted with said columnar ceramic elements.
