The present invention provides a double helix coupled vane forward wave crossed-field amplifier utilizing individually cooled vanes in the RF slow-wave circuit. Specifically, a double helix coupled vane is machined to create a channel in the shape of a "U" on one side of the vane. A vane coolant tube formed in a corresponding U-shape is inserted and brazed to the machined vane. The vane assembly is then attached to the anode body of which the backwall has holes formed to accept the coolant tubes from each vane. Divided backwall coolant channels are brazed to the outside of the anode, thereby placing in fluid communication the coolant channels to the vane coolant tube. Accordingly, coolant is cycled through each vane tube and individual vanes of the anode are thus cooled.
A crossed-field amplifier, comprising:
A double-helix coupled vane for use in an RF slow-wave circuit of a forward wave crossed-field amplifier, said vane comprising:
A crossed-field amplifier having a pair of magnetic polepieces providing a magnetic field which crosses an electric field established between a cathode and an anode, said anode being disposed radially along a backwall inside the amplifier and coaxially around the cathode, comprising:
