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.

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.

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 EB 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.
