    Abstract: A quick starting magnetron having two cathodes, one of low heat inertia and thermally emissive for starting purposes and the second of high heat inertia positioned between the magnetron anode and the first cathode. The second cathode is apertured to allow electrons to pass through from the first cathode and is arranged to partially shield the first cathode from electron bombardment during normal running of the magnetron.
