摘要： To provide a magnetron capable of reducing noises in a low frequency band of 30 MHz or less without deteriorating the stability of a load depending on phases, and also ensuring the precision of assembly dimensions without increasing the number of components, a coiled filament 3 is arranged between an input-side end hat 61 and an output-side end hat 7 which are supported by a cathode supporting rod 8. A larger-diameter boss 61a in the end hat 61 extends to the interior of an interaction space, a smaller-diameter boss 61b and one end 3a of the filament 3 are secured to each other, and the other end 3b is secured to a boss 7a of the end hat 7. Here, the dimension of an axial free length part F which forms an electron emission part which is not secured to the end hats 61 and 7 of the filament 3 is set to 50% or more and 80% or less of the axial dimension H of plate-like vanes 2, and the electron emission part is arranged so as to be displaced to the output side.

摘要： In the magnetron, an upper end hat 122A is used as a composing element of a cathode structure member 12A and includes a portion 122Aa which is in contact with one end portion 121a of a filament coil 121. The thickness of the portion 122Aa is reduced, whereby the portion 122Aa is held not in contact with a center lead 124. Owing to this, heat generated in the filament coil 121 can travel to the upper end hat 122A without traveling directly to the center lead 124. Therefore, even when the quantity of input power is reduced to such a degree as to be able to reduce noise, or even when the electron radiation area of the filament coil 121 is reduced, the getter effect can be displayed fully. As a result of this, noise reduction and cost reduction can be realized at the same time.
摘要翻译：在磁控管中，上端帽122A用作阴极结构件12A的组成元件，并且包括与灯丝线圈121的一个端部121a接触的部分122Aa。部分122Aa的厚度减小，由此部分122Aa被保持为不与中心引线124接触。由此，灯丝线圈121中产生的热可以行进到上端帽122A而不直接行进到中心引线124。因此，即使当输入功率的量减少到能够降低噪声的程度时，或者即使当灯丝线圈121的电子辐射面积减小时，也可以充分地显示吸气剂效果。作为其结果，可以同时实现降噪和降低成本。

摘要： In an interaction space (7) defined between a cathode (2) and forward ends of vanes (3), an even direct-current magnetic field is applied by magnets (8) along the axial direction of the cathode (2). Direct-current or low-frequency high voltage is applied between the cathode (2) and the respective vanes (3). Spaces (6) surrounded by respective two adjacent vanes (3) and the inner wall of the anode cylinder (4) define cavity resonators, which generate high-frequency electric fields concentrated to the forward end portions of the respective vanes (3) and partially leaking in the interaction space (7). Under such conditions, an electron group emitted from the cathode (2) rotates about the cathode (2) in the interaction space, whereby interaction takes place between the electron group and the high-frequency electric fields to oscillate microwaves. At this time, undesired higher harmonics generated with the microwaves of basic frequency are suppressed by arranging inner strap rings (5a) in positions separated from the forward ends of the vanes (3) to exceed a prescribed interval.
