Abstract: 1. A rugged combustion-heated electron tube comprising: a metallic conica-shaped anode structure; a metallic conically-shaped cathode structure insulatedly and coaxially mounted in spaced relationship to said anode structure; a metallic conically-shaped grid structure insulatedly and coaxially mounted in spaced relationship between said anode structure and said cathode structure; first and second annular insulating spacer-seals separating said anode structure from said grid structure and said grid structure from said cathode structure, said spacer-seals in combination with said anode structure and said cathode structure providing a hermetically-sealed envelope containing said grid structure; and a combustible material mounted exteriorly of said envelope in proximity to said cathode structure, said combustible material being adapted to heat said cathode structure to an operating temperature.
