Abstract
An uncoated radiative heating filament wire is electrically and thermally isolated from the cathode of a high power magnetron. The filament wire helically surrounds the cathode support rod and is suspended above the support rod surface by ceramic members. A reflective shell envelops the helical filament wire and cathode support rod. The shell reflects radiated heat from the filament wire evenly upon the cathode support rod.
