摘要： The present invention includes an electron-discharge signal system with a supercharged electron source and process therefor. The system may be any signal modification unit such as a klystron, magnetron, traveling wave tube, etc. The system includes a heat-responsive electron source, supercharger, collector, a wave modification assembly, and a bleeder module. The electron source discharges an electron beam along a predetermined electron path. The supercharger heats the electron source upon absorption of electromagnetic radiation of a predetermined signal characteristic redirected by the system. The bleeder module redirects a portion of the system's output signal to the supercharger, which heats in response thereto. In other embodiments, the system may be operated entirely by electromagnetic radiation from a freestanding signal source.

摘要： An electron gun for generating an electron beam is provided, which includes a secondary emitter. The secondary emitter includes a non-contaminating negative-electron-affinity (NEA) material and emitting surface. The gun includes an accelerating region which accelerates the secondaries from the emitting surface. The secondaries are emitted in response to a primary beam generated external to the accelerating region. The accelerating region may include a superconducting radio frequency (RF) cavity, and the gun may be operated in a continuous wave (CW) mode. The secondary emitter includes hydrogenated diamond. A uniform electrically conductive layer is superposed on the emitter to replenish the extracted current, preventing charging of the emitter. An encapsulated secondary emission enhanced cathode device, useful in a superconducting RF cavity, includes a housing for maintaining vacuum, a cathode, e.g., a photocathode, and the non-contaminating NEA secondary emitter with the uniform electrically conductive layer superposed thereon.

摘要： A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multistages of the depressed collector are connected to high energy voltage sources of different potentials. The klystron tube with the multistage depressed collector is uniquely used here for the first time in a ground based satellite or terrestrial communications system.

摘要： 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 standard rectangular waveguide. The invention utilizes current multiplication of a seed electron beam, comprising an energetic electron beam to impact a thin foil surface with high electric field. 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. Both self-excited oscillator and amplifier configurations are envisaged. Also included is both a self-excited microwave generator and an amplifier, using a temporally modulated laser to generate a seed electron beam that is amplified. Methods to tune the oscillator are described that allow tunability over a full waveguide band.

摘要： 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.

摘要： In an electron tube sealing structure, a cylindrical insulator is metallized to produce metallized layers on both end surfaces, and sealing metal members are soldered to the metallized layers correspondingly, so that a vacuum chamber is provided in the interior of the cylindrical insulator. The cylindrical insulator is provided with at least one salient portion at an inner end thereof. The salient portion is parallel to a direction of an electric field produced by a voltage applied across the sealing metal members, and shields one of the metallized layers which is positioned on the side of a negative electrode in regard to the vacuum chamber, so that the emission of electrons is avoided from the corresponding metallized layer to prevent a creeping discharge from being induced on the inner surface of the cylindrical insulator.
