摘要： PROBLEM TO BE SOLVED: To provide a magnetron that suppresses noise level by the movement of undesired electrons and can prevent degradation of oscillation efficiency.
SOLUTION: The electrons emitted from a negative electrode part 4 receive action of vertical electric field and rotate in accordance with the Fleming's rule, and form a space charge layer. Further, they receive action of high frequency electric field between the vanes 11 and, by forming electron flux 9, become an electron group 8 and rotate so as to almost touch the top end of the vanes 11 as shown by the arrow mark. Then, chamfering process with a radius r of 0.4-0.6 times of the thickness t of the vanes 11 is applied to the top end corner of the vanes 11 on the opposing side to the rotation movement of the electron group 8, and one-side chamfering process is applied so that the relationship between the thickness t of the vane 11 and a minimum distance w between each of the adjoining vanes becomes w/(t+w)≤0.5.

摘要： PROBLEM TO BE SOLVED: To obtain a magnetron capable of sufficiently exhibiting a getter effect even if input power is decreased to an extent for reducing reduce noise or an electron emitting area of a filament coil is decreased. SOLUTION: A portion 122Aa which contacts with one end 121a of a filament coil 121 of an upper end hat 122A being a component of a cathode structure 12A is made thin and placed in a non-contact state with a center lead 124. Thereby, heat which is generated in the filament coil 121 is transmitted to the upper end hat 122A without being transmitted directly to the center lead 124, thereby, the getter effect can be sufficiently exhibited even if the input power is decreased to the extent for reducing the noise or the electron emitting area of the filament coil 121 is decreased. As a result, the reduction of noise and the reduction of cost can be achieved simultaneously. COPYRIGHT: (C)2008,JPO&INPIT
