Title:
PLATE TYPE MAGNETRON
Document Type and Number:
Japanese Patent JPH10241585
Kind Code:
A
Abstract:
To provide a plate type magnetron with a high general versatility which can efficiently generate a microwave with a required output and frequency.
An interaction space is formed with a negative electrode 12 which generates electrons and a positive electrode 11 where a plural of vanes are provided by the same pitch. A pole piece 13 with bellows which may freely expanded and contract a movable magnet part 15 are provided at both ends of the interaction space. The frequency of a micro wave is changed by varying a distance between the magnets by an operation of a york 17. The output of the microwave is changed by altering the potential of end hats 16.
