摘要： 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.

摘要： In a magnetron anode, an anode surrounds a central cathode. The anode is of a segmented structure having a plurality of annular segments stacked together along its length. Each annular segment includes a strap, the strap being distributed substantially along the entire axial length of the anode vanes. This enables mode separation to be achieved, even for long anode lengths and, hence, permits high power operation to be achieved. In addition, the segmented structure of the anode gives a mechanically robust design.

摘要： An improved low power pulsed anode magnetron is provided having a cylindrical cathode centrally disposed within a plurality of radial anode vanes. An interaction region is provided between the surface of the cathode and the anode vane tips. A ratio of the anode-to-cathode space over the center-to-center distance between adjacent vane tips is within a range between 0.95 and 1.05. The cathode is joined to a magnetic polepiece assembly which channels magnetic flux to the interaction region. Both the cathode and the polepiece are mechanically adjustable from external to the magnetron to reposition the cathode and polepiece with respect to the anode vanes. The cathode surface is formed from an active nickel alloy which is cleaned by a chemical process followed by a high temperature and vacuum firing. An emissive surface is applied over the cleaned cathode surface. The output spectrum of the magnetron is calibrated by applying a sequential pulsed input of increasing amplitude, and adjusting the relative cathode-anode position until the frequency spectrum remains constant.
