Abstract: The present disclosure is directed to axial strapping of a multi-core (cascaded) magnetron. The multi-core (cascaded) magnetron includes a cathode and a plurality of cores (anodes) arranged in an axial direction along the cathode. Each of the cores may have a plurality of vanes arranged periodically in an azimuthal direction along a circumference of the cathode and forming by such a way a plurality of resonant cavities. The multi-core (cascaded) magnetron further includes groups of axial straps coupling each of the cores together in the axial direction along the cathode. For example, a first group of axial straps couple the first plurality of vanes of a first core to the second plurality of vanes of a second core. In an embodiment, the axial straps are configured to provide phase synchronization of electromagnetic oscillations induced inside each of the plurality of cores.

Abstract: 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.

Abstract translation: 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中产生的热量可以行进到上端帽122A而不直接行进到中心引线124.因此，即使当 输入功率降低到能够降低噪声的程度，或者即使当灯丝线圈121的电子辐射面积减小时，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。
