Abstract

The coaxial line electric resonator of a velocity-modulated electric discharge tube of the kind described in Specification 537,490, [Group XL], is made of a non-magnetic alloy of nickel and copper containing 44 per cent. of nickel, and copper plated. Specification 582,615, [Group XL], also is referred to.
