Abstract: A system for an electro magnetic oscillator tube with enhanced isotopes is disclosed herein having at least one magnetron layer. Each layer has a first magnet, a conduction block, and a second magnet of opposite polarity. The conduction block is disposed in a plane about an emitter of isotopic particles, where an opposite electrical polarity relative to the emitter forms between the emitter and the conduction block. The conduction block has an RF port, an interaction space in its inner periphery, and a polar array of resonant cavities forming along its outer periphery, and a diamond or similar material coating the conduction block surfaces. The system also has a connection between selected groups of resonant cavities at locations of like electrical polarity, wherein the connections have conductive strapping elements within the conduction block.

Abstract: A crossed field device for generating electromagnetic emissions includes an anode having a first slow-wave structure having a plurality of first vanes separated by cavities formed therebetween and a second slow-wave structure having a plurality of second vanes separated by cavities formed therebetween. At least one of the first vanes is laterally aligned with one of the second vanes. The first vanes are offset from the second vanes by an offset distance so that at least one of the first vanes is not laterally aligned with a second vane and at least one of the second vanes is not laterally aligned with a first vane. The device further includes a cathode disposed in a space located between first and second vanes. A magnetic element generates a magnetic field (B), which is oriented orthogonally to an electric field (E) formed by the anode and cathode to generate EM emissions.

Abstract: A cascaded magnetron device has an elongate cathode shank extending along its axis and a series of tubular anode elements placed end to end in a linear cascade surrounding the cathode shank along at least part of its length. Each adjacent pair of anode elements is separated by a conductive, annular pin down disc, and the cathode shank has a series of spaced bands of field emitting material separated by non-emitting regions, each band being located within a respective one of the anode elements and spaced inwardly from the ends of that element. Suitable power inputs and magnetic field generators are provided for generating electron emission and oscillation in the interaction zone between each emitting band and the anode element surrounding that band, and suitable extraction devices are provided for extracting power from each of the interaction zones, the arrangement producing phase-locking of the cascaded magnetron bodies.

Abstract: An uncoated radiative heating filament wire is electrically and thermally isolated from the cathode of a high power magnetron. The filament wire helically surrounds the cathode support rod and is suspended above the support rod surface by ceramic members. A reflective shell envelops the helical filament wire and cathode support rod. The shell reflects radiated heat from the filament wire evenly upon the cathode support rod.

Abstract: A method of producing a magnetron is disclosed which has a getter on at least one of the opposed surfaces of two end shields of a cathode. The getter is formed in such a manner that after the cathode is assembled, a paste containing a getter metal powder is coated on at least one of the opposed surfaces of the end shields and dried before the filament of the cathode is carburized and then while the magnetron is being exhausted, the dried paste is sintered to produce a sintered substance of the getter metal powder.
