Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
A COAXIAL MAGNETRON COMPRISING A CATHODE, A PLURALITY OF ANODE RESONATORS ADJACENT SAID CATHODE AND DEFINING AN INTERACTION REGION, MAGNETIC MEANS FOR ESTABLISHING A DIRECT CURRENT MAGNETIC FIELD WITHIN SAID INTERACTION REGION, A CIRCULAR CAVITY RESONATOR ADJACENT SAID ANODE RESONATORS, SAID ANODE RESONATORS AND SAID CAVITY RESONATOR HAVING A COMMON WALL PORTION WITH SLOTS THEREIN FOR COUPLING SELECTED ANODE RESONATORS TO SAID CAVITY RESONATOR, TUNING MEANS PROVIDED ON ONE OF THE INNER WALLS OF SAID CAVITY RESONATOR OTHER THAN SAID COMMON WALL, SAID TUNING MEANS INCLUDING A FERRITE MATERIAL, AN ELECTROMAGNETIC MEANS EXTERIOR OF SAID CAVITY RESONATOR FOR MODIFYING THE EFFECTIVE PERMEABILITY OF SAID FERRITE MATERIAL AND THEREBY MODIFY THE FREQUENCY OF SAID COAXIAL MAGNETRON.
