Abstract: A field emitter device utilizing a gate electrode adjacent a carbon fiber electron emitter cathode for controlling the initial flow of electrons between the cathode and a collector element. Subsequent disconnect of the gate electrode from its power source does not affect the electron flow and thereby provides a bistable memory type device. Luminescent material on the collector provides a light emission display at points corresponding to electron flow between the emitter and the collector.

Abstract: In field emission systems having beam current regulation by use of modulating field strengths from a control or Wehnelt electrode adjacent the emission electrode, the varying field strengths produce a focus instability of the emitted beam. By the precise spacing of the emission tip, Wehnelt electrode and first accelerating electrode, and by the precise aperture diameters of the Wehnelt and first accelerating electrodes, the beam focus remains stabilized for modulating field strength variations.

Abstract: An ion plasma electron gun for the generation of large area electron beams with uniform electron distribution. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid into a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid and the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and a uniform electron distribution which is substantially the same as the ion distribution of the ion beam impinging upon the cathode. Control of the generated electron beam is achieved by applying a control voltage between the wire and the grounded housing of the plasma chamber to control the density of positive ions bombarding the cathode.

Abstract: An electron beam controlled switch employing a radial geometry and a Wire-Ion Plasma-Electron gun (WIP E-gun) as an electron source is disclosed. The switch comprises an inner cylinder that serves as the WIP E-gun cathode, a cylindrical grid that serves as the WIP E-gun anode, an array of fine wire anodes disposed in the WIP E-gun ionization chamber, a foil support cylinder to support the foil windows which also serve as the switch anode, and an outer cylinder which also serves as the switch cathode. The WIP E-gun and ionization chamber is gas filled at low pressure, while the switch cavity is filled with a high pressure gas. A voltage pulse is applied to the wire anodes to ionize the gas in the ionization chamber. The ions are extracted through the chamber grid and accelerated through a high voltage to bombard the E-gun cathode. The electrons emitted from the ion bombardment are accelerated outwardly through the high voltage, penetrate through the foil windows and into the pressurized gas in the switch cavity. The high energy electrons ionize the gas between the switch anode and cathode, thereby turning "ON" the switch. In the absence of the electron beam, the switch gas deionizes and switch conduction is quickly extinguished.

Abstract: Disclosed is a pulsed electron beam gun for generating a high current, short duration pulse which is received by a pulse detection circuit. The gun has a gated electron beam emitting area, a beam deflection and sweeping area and a beam pulse detector. Magnetic collimating means having lines of force along an axis in the direction of the electron beam surrounds the aforementioned structure. The magnetic collimating means intensifies the density and strength of the electron beam once it is emitted from its source of emission and is gated through the electron gate. A conventional pulse source delivers a low voltage pulse and a delayed pulse. The internal impedance of the pulse source is matched at the location of the electron gun where the pulses are applied to the electron gun components. The first pulse, at the beam gate, causes a short burst of electrons to be emitted. The delayed pulse is applied to the deflection means to sweep the electron beam symmetrically across the electron passing aperture in the plate.

Abstract: Disclosed is a method and apparatus for producing a high electron beam current having a low energy spread at a high brightness of the beam and a uniform intensity distribution. The electron beam is extracted from an emission current which consists of used emission current and unused emission current. The used emission current has a uniform intensity distribution. The apparatus produces a negligibly small unused emission current by using both a frustum shaped cathode and a multi-electrode. The cathode comprises a thermoelectron emissive material having a low work function and one or more thin layers which cover the side surface of the cathode. A material of the outermost thin layer has a high work function. The multi-electrode consists of the cathode, a first grid electrode, a second grid electrode and an anode electrode. The used emission current is generated from the top surface of the cathode. The unused emission current that is generated from the side surface of the cathode is negligibly small. The top surface is immersed into a strong accelerating electric field. By adjusting the field at the top surface, an emission current density from the top surface can be varied in the range of one to several hundred times of the saturation current density at an operating temperature. Methods for manufacturing the cathode are provided.

Abstract: An electron and ion accelerator includes plural spaced electrodes which are apertured to define a gas discharge path and supported at their peripheries by insulative means. A gas supply provides low pressure gas capable of producing electrons and ions in the gas discharge path. A voltage applied between the at least two electrodes establishes an electrical potential between them such that a spark-like gas discharge occurs along the gas discharge path. The current density obtainable in the low pressure gas is substantially higher than the density of an electron or ion flow in a vacuum.
