Solution Overview
Problem
Multi-core magnetrons face challenges in synchronizing electromagnetic oscillations between individual cores, leading to potential energy loss and inefficient operation.

Engineering Contradiction Analysis
1Power
If multiple cores are combined to form a multi-core magnetron, then the power output is increased, but the synchronization of electromagnetic oscillations between cores deteriorates
Solution Approach 1:
Axial straps are introduced as intermediary coupling elements between adjacent cores. These straps provide a controlled electromagnetic coupling path that forces phase synchronization of oscillations between cores, resolving the synchronization problem that arises when multiple cores are combined to increase power output.
Solution Approach 2:
The axial straps have a specific predetermined length designed to provide a phase difference of approximately 180 degrees between adjacent cores. By changing the physical parameter (length) of the coupling element, the phase relationship between cores is controlled to achieve constructive interference and synchronized operation, thereby maintaining reliability while increasing power output.
2Reliability
If axial straps are added to couple adjacent cores, then phase synchronization is achieved, but the device complexity increases
Solution Approach 1:
The coupling function is segmented into discrete axial strap elements positioned at specific locations between cores. Each strap independently provides phase synchronization for its adjacent core pair, allowing the synchronization function to be distributed and modular rather than requiring a complex integrated coupling structure.
Solution Approach 2:
The axial straps serve multiple functions: they provide electromagnetic coupling between cores, establish phase synchronization, and act as part of the resonant structure. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving reliable phase synchronization.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration achieves phase synchronization of electromagnetic oscillations, enhancing the operational efficiency of multi-core magnetrons by ensuring synchronized energy transfer between cores.
Implementation Method 1
axial straps are used to couple vanes of adjacent cores of a multi-core (cascaded) magnetron. The axial straps provide a direct electrical connection between one or more vanes of the adjacent cores.
Implementation Method 2
The axial straps are provided having a predetermined length selected to make an electrical length between centers of adjacent cores of a multi-core (cascaded) magnetron equal or proportional to one half of a wavelength of electromagnetic oscillations induced inside the cores. This structure results in phase synchronization of electromagnetic oscillations induced inside the adjacent cores.

AI summary
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.
