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: Particles emitted by radio-isotopic by-products of nuclear fission are used as a power source at the cathode of a magnetron system. Particles include high energy electrons having a large associated EMF. In the system a radial electrical vector E, between the cathode and anode, interacts with an axial magnetic vector B vector to produce an E×B force that rotates the particles about the system axis. These emissions are within a set range of velocities. The angular velocity and geometry of a rotating field, known as a space charge wheel (SCW), may be modulated by an external RF inputs to cavities of an anode block and the use of concentric biasing grids between the cathode and anode block. The SCW induces LC values into cavities of the anode, exciting them and producing electrons resonance which may be used to generate power.

Abstract: 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.
