摘要：A high power amplifier for amplifying millimeter-wave radiation comprising: a length of metallic waveguide tapered from a small cross- ctional end to a larger cross-ctional end; a magnetron-type electron injection gun for injecting a spiral beam of relativistic electrons at the small end of the waveguide for propagation axially therein so that the wall radius of the tapered waveguide increas in the downstream direction of the electron beam; an input coupler for launching electromagnetic waves to be amplified into the waveguide at the large waveguide end thereof such that the individual frequencies in the input waves are reflected at various points along the constriction of the waveguide taper so that they copropagate with and are amplified by the electron beam; and a magnetic circuit for generating an axial magnetic field within the tapered waveguide with a unique profile approximately in accordance with the following equation to maintain synchronism: ##EQU1## where the z subscript is the waveguide axial direction, the ⊥ subscript designates the direction perpendicular to this axial direction, and the o subscript reprents tho quantities at the entrance point for the electron beam into the waveguide.

This device has been found experimentally to have negligible launching loss and low nsitivity to electron velocity spread.
