Abstract
A collector for use in a travelling wave tube includes a central metallic re that has a peripheral ceramic insulator with the central metallic core having a plurality of circumferentially spaced primary slots extending inwardly from the periphery and an equal number of secondary slots extending perpendicular to the primary slots adjacent the periphery of the electrode. The primary slots define a plurality of fingers and the secondary slots act as hinges for the fingers.
Claims9
A traveling wave tube having means for supplying a beam to one end of the tube and a collector which receives said beam at an opposite end of said tube said collector comprising a metal electrode having a ceramic insulator secured to the periphery thereof and stress-relief means for said electrode including a plurality of spaced substantially planar primary slots extending from the periphery of said metal electrode, with planes offset from the center of said metal electrode, and secondary slots extending from at least one edge of said primary slots.
A collector for use in a traveling wave tube comprising a circular elongated center electrode and a surrounding ceramic insulator having abutting surfaces secured to each other including means defining a plurality of circumferentially spaced primary slots extending from the surface of electrode, said primary slots being substantially planar with planes offset to one side of the center of the electrode, and an equal number of short secondary slots formed contiguous with the edge of respective primary slots and adjacent the periphery of said electrode.
