Abstract: A thin diamond electron beam amplifier. The illumination side of a thin diamond is illuminated by a seed electron beam creating electron-hole pairs in the diamond. A voltage potential provides an electric field between the illumination side of the diamond and an acceleration grid opposite the emission side of the diamond. Electrons released in the diamond are accelerated through the emission side of the diamond toward the acceleration grid creating an amplified electron beam. Preferred embodiments of the present invention are useful to provide flat panel displays and replacements for thermionic cathodes.

Abstract: A millimeter wave device. Pulses of electrons illuminate a diamond switch at rates of 1 billion to 100 billion pulses per second. The diamond switch connects a high voltage source to a millimeter wave transmitter or other load. In preferred embodiments the electron pulses are provided by a klystron or a traveling wave tube.

Abstract: An electronic device for amplifying microwave or millimeter wave signals. A microwave or millimeter wave input signal stimulates a gated field emission array to produce a density modulated beam of electrons containing about 1 billion to 1,000 billion bunches or pulses per second which in turn illuminates a thin diamond target in a diamond switch connecting a load to a high voltage source. Each electron in each pulse creates a large number of electron hole pairs in the diamond. The high voltage bias across the diamond causes most of the very large number of pairs to be swept through the diamond target producing a high current surge in less than one half the period of the designed output frequency. Induced RF currents are set up within the resonant output cavity in response to the current flowing within the diamond. In summary, each surge of current produces an electromagnetic pulse at the load. Thus, an electromagnetic millimeter wave is produced with a frequency equal to the frequency of the signal output.

Abstract: A beam of radiation radiates in sequence an array of semi-conductor switches at an extremely rapid rate. Electron-hole pairs created by radiation permit the semiconductor switches to conduct electric current for a very brief period of time.

Abstract: A high power fast switch for generating pulses of current to a load from a high voltage power source. A laser beam illuminates a cathode which simulates the emission of pulses of electrons which illuminate a diamond target. The pulses of electrons cause the diamond target to become conductive permitting high power pulses of electric current to pass through the diamond target from a high voltage source to a load. In a preferred embodiment a Klystron buncher compresses the electron pulses onto the diamond target.
