Radial-gain/axial-gain crossed-field amplifier (radaxtron)

摘要

A crossed-field amplifier comprises a cylindrical array of anode circuits for broad-band high-power crossed-field operation at millimeter waves. The electric field between the cylindrical anode and the surrounding cylindrical cathode is radial and the magnetic field is axial in the space between the anode and cathode. This space is the interaction region where the power is uniformly distributed over the circumference of each cylindrical array. Power flows radially in and out of the elements of the anode circuit and also axially along the cylindrical TE01 guide within the cylindrical anode. The guide is equipped with damping elements for mode control and filter elements for controlling the overall gain, bandwidth, and stability. Because of the radial flow and axial flow of power in the amplifier, it has been termed a Radaxtron.
