摘要： The present invention provides a magnetron which can conduct more magnetic flux in the active space at the periphery of a cathode structure to thereby further improve the efficiency of a magnetic circuit. The magnetron of the present invention includes an anode cylinder on which inner wall a plurality of anode vanes are provided, a pole piece provided on an end side of the anode cylinder, a circular magnet provided on the vicinity of the pole piece, and a magnet ring provided between the anode cylinder and the circular magnet. An outer radius of the magnet ring is smaller than or equal to the outer diameter of the circular magnet and larger than or equal to the outer diameter of the anode cylinder. The magnet ring has a portion on a surface of the pole piece side whose normal line is non-parallel to the central axis of the anode cylinder.

摘要： A multi-stage depressed collector (60) for receiving energy from a small orbit gyrating electron beam (61) employs a plurality of electrodes (66, 67, 68) for sorting the individual electrons on the basis of their total energy level. Magnetic field generating coils (70, 72, 74) for producing magnetic fields and magnetic iron pole pieces (75-81) for magnetic field shaping produce adiabatic and controlled non-adiabatic transitions of the incident electron beam to further facilitate the sorting.

摘要： Provided is a low-cost magnetron that is excellent in productivity without any adverse effect on characteristics.
Two large and small strap rings 11 (11A and 11B) are only disposed at lower ends, or input sides, of a plurality of vanes 10 (10A and 10B) in the direction of a tube axis m. Diameter Rip of a protruding flat surface 41 of an input side pole piece 18 is larger than diameter Rop of a protruding flat surface 40 of an output side pole piece 17. Therefore, it is possible to provide a practical magnetron without a significant decrease in productivity or characteristics from a conventional one, while cutting costs by reducing the number of parts with the use of two strap rings on one side.
