    Abstract: A semiconductor source of emission electrons which uses a target of a wide bandgap semiconductor having a target thickness measured from an illumination surface to an emission surface. The semiconductor source is equipped with an arrangement for producing and directing a beam of seed electrons at the illumination surface and a mechanism for controlling the energy of the seed electrons such that the energy of the seed electrons is sufficient to generate electron-hole pairs in the target. A fraction of these electron-hole pairs supply the emission electrons. Furthermore, the target thickness and the energy of the seed electrons are optimized such that the emission electrons at the emission surface are substantially thermalized. The emission of electrons is further facilitated by generating negative electron affinity at the emission surface. The source of the invention can take advantage of diamond, AlN, BN, Ga1nullyAlyN and (AlN)x(SiC)1nullx, wherein 0nullynull1 and 0.2nullxnull1 and other wide bandgap semiconductors.

    Abstract: The present invention pertains to an electron gun. The electron gun comprises an RF cavity having a first side with an emitting surface and a second side with a transmitting and emitting section. The gun is also comprised of a mechanism for producing an oscillating force which encompasses the emitting surface and the section so electrons are directed between the emitting surface and the section to contact the emitting surface and generate additional electrons and to contact the section to generate additional electrons or escape the cavity through the section. The section preferably isolates the cavity from external forces outside and adjacent the cavity. The section preferably includes a transmitting and emitting screen. The screen can be of an annular shape, or of a circular shape, or of a rhombohedrion shape. The mechanism preferably includes a mechanism for producing an oscillating electric field that provides the force and which has a radial component that prevents the electrons from straying out of the region between the screen and the emitting surface. Additionally, the gun includes a mechanism for producing a magnetic field to force the electrons between the screen and the emitting surface. The present invention pertains to a method for producing electrons. The method comprises the steps of moving at least a first electron in a first direction. Next there is the step of striking a first area with the first electron. Then there is the step of producing additional electrons at the first area due to the first electron. Next there is the step of moving electrons from the first area to a second area and transmitting electrons through the second area and creating more electrons due to electrons from the first area striking the second area. These newly created electrons from the second area then strike the first area, creating even more electrons in a recursive, repeating manner between the first and second areas.

    Abstract: Embodiments of the invention provide a novel, low-power X-ray tube and X-ray generating system. Embodiments of the invention use a multichannel electron generator as the electron source, thereby increasing reliability and decreasing power consumption of the X-ray tube. Unlike tubes using a conventional filament that must be heated by a current power source, embodiments of the invention require only a voltage power source, use very little current, and have no cooling requirements. The microchannel electron generator comprises one or more microchannel plates (MCPs), Each MCP comprises a honeycomb assembly of a plurality of annular components, which may be stacked to increase electron intensity. The multichannel electron generator used enables directional control of electron flow. In addition, the multichannel electron generator used is more robust than conventional filaments, making the resulting X-ray tube very shock and vibration resistant.
