ABSTRACT:
A magnetron includes an evacuated envelope having therein a cathode assembly. An anode electrode surrounds the cathode assembly. The cathode assembly is formed of a helically wound filament having a quadrilateral cross-section. One of the surfaces of the quadrilateral cross-section filament is wider than the others. The wider surface of the filament faces the anode electrode. The quadrilateral cross-section thereby increasing the sag resistance of the filament.
