    Abstract: Generating and frequency tuning of modulated high current electron beams and a specific efficient, high current, frequency-tunable device for generating intense radio frequency (RF), microwave electromagnetic fields in a rectangular waveguide. Current multiplication of a modulated seed electron beam is created by an energetic electron beam impacting a thin foil surface. The transmissive-electron-multiplier foils also mitigate both space charge expansion and improve beam propagation effects, by shorting of the radially directed electric field at the axial location of the foil(s). Foil thinness and intensity of the exit fields provide for a multiplication process occurring in a fraction of an RF period. Also included are both a self-excited microwave generator and an amplifier, using a temporally modulated laser to generate a modulated seed electron beam that is amplified. Methods to tune the oscillator are described that allow tunability over a full waveguide band.

    Abstract: A display device has a display screen for displaying image information, and cathode means comprising an emitter material for emitting electrons. The emitted electrons are collected by an electron concentrator which redistributes the electrons in a homogenous electron beam (EB). The emitter material is arranged on a first surface excluding a first impact area on which positive ions land that pass through the electron concentrator. Therefore, substantially no emitter material is provided at the first impact area, so that damage inflicted on the cathode means by the positive ions is reduced. Preferably, the display device has a pumping chamber between the cathode means and a back plate, for removing residual gases from the display device.

    Abstract: The present invention pertains to an electron gun that generates multiple electron bunches and the application of this gun to produce rf energy. The electron gun comprises an rf input cavity having a first side with multiple emitting surfaces and a second side with multiple transmitting and emitting sections. The gun is also comprised of a mechanism for producing a rotating and oscillating force which encompasses the multiple emitting surfaces and the multiple sections so electrons are directed between the multiple emitting surfaces and the multiple sections to contact the multiple emitting surfaces and generate additional electrons and to contact the multiple sections to generate additional electrons or escape the cavity through the multiple sections. The multiple sections preferably isolates the cavity from external forces outside and adjacent the cavity. The multiple sections preferably include multiple transmitting and emitting grids. The multiple grids can be of an annular shape, or of a circular shape, or of a rhombohedron shape. The mechanism preferably includes a mechanism for producing a rotating and 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 multiple grids and the multiple emitting surfaces. Additionally, the gun includes a mechanism for producing a magnetic field to force the electrons between the multiple grids and the multiple emitting surfaces. The present invention pertains to a method for producing multiple electron bunches. 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, repetitive manner between the first and second areas. An apparatus is provided for accelerating electron bunches to high energy. A means is given for producing an axial magnetic field in the axial direction so as to guide electrons into an output cavity for generating rf energy from the electrons passing therethrough. An output cavity is given for generating rf energy when multiple electron bunches pass through it. Finally, a collector is provided for electrons which have given up most of their energy to the output cavity. The present invention pertains to an electron gun. The electron gun comprises an rf cavity having a first side with multiple non-simultaneous emitting surfaces and a second side with multiple transmitting and emitting sections. The electron gun also comprises a mechanism for producing a rotating and oscillating force which encompasses the multiple emitting surfaces and the multiple sections so electrons are directed between the multiple emitting surfaces and the multiple sections to contact the multiple emitting surfaces and generate additional electrons and to contact the multiple sections to generate additional electrons or escape the cavity through the multiple sections. The present invention pertains to an apparatus for generating rf energy. The apparatus comprises a mechanism focusing non-simultaneous multiple electron bunches. The apparatus also comprises an output cavity which receives non-simultaneous multiple electron bunches and produces rf energy as the non-simultaneous multiple electron bunches pass through it. 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 at a first time. Then there is the step of moving at least a second electron in the first direction at a second time. Next, there is the step of striking a first area with the first electron. Next, there is the step of producing additional electrons at the first area due to the first electron. Then, there is the step of moving electrons from the first area to a second area. Next, there is the step of transmitting electrons to the second area and creating more electrons due to electrons from the first area striking the second area. Then, there is the step of striking a third area with the second electron. Next, there is the step of producing additional electrons at the third area due to the second electron. Next, there is the step of moving electrons from the third area to a fourth area. Then, there is the step of transmitting electrons to the fourth area and creating more electrons due to electrons from the third area striking the fourth area.
