Imaging the output field pattern of a 110-GHz gyrotron with pulsed magnetic field using recombination continuum emitted by a slab of the Cs-Xe dc discharge

It has been demonstrated that recombination continuum emitted by a slab of the positive column of the Cs-Xe discharge can be used successfully to image moderate-power pulsed millimeter waves. Using this technique, the output field patterns of a 110-GHz 10-kW gyrotron with a pulsed magnetic field have been imaged.
