ABSTRACT:
A magnetron electron discharge device preferably for use in microwave heating or cooking apparatus has a cylindrical resonant anode structure surrounding a concentric electron emitting filament which is supported directly between re-entrant end closures housing magnet members which are external to the vacuum envelope but are so located as to achieve high magnet circuit efficiency, rugged construction and low spurious noise output.
