Patent number: 10624199Abstract: A system for injecting radio frequency (RF) pulses into an RF linear accelerator (RF LINAC) cavity is described. In accordance with the description an RF power amplifying element, typically a compact planar triode (CPT), is directly mounted to an outside of a hermetically sealed RF cavity. The direct mounting of the RF power amplifying element places the antenna—responsible for coupling power into the RF cavity—physically on the RF cavity side of a hermetic high-voltage (HV) break. The RF input, RF circuitry, biasing circuitry, and RF power amplifier are all outside of the vacuum cavity region. The direct mounting arrangement facilitates easy inspection and replacement of the RF power amplifier, the RF input and biasing circuitry. The direct mounting arrangement also mitigates the deleterious effects of multipactoring associated with placing the RF power amplifier and associated RF circuitry in the vacuum environment of the RF LINAC cavity.Type: GrantFiled: November 3, 2017Date of Patent: April 14, 2020Assignee: Starfire Industries, LLCInventors: Robert A. Stubbers, Brian E. Jurczyk, Thomas J. Houlahan, Jr., James M. Potter

Patent number: 9948011Abstract: A superluminal antenna element integrates a balun element to better impedance match an input cable or waveguide to a dielectric radiator element, thus preventing stray reflections and consequent undesirable radiation. For example, a dielectric housing material can be used that has a cutout area. A cable can extend into the cutout area. A triangular conductor can function as an impedance transition. An additional cylindrical element functions as a sleeve balun to better impedance match the radiator element to the cable.Type: GrantFiled: November 16, 2016Date of Patent: April 17, 2018Assignee: Los Alamos National Security, LLCInventors: John Singleton, Lawrence M.

Patent number: 8274806Abstract: The systems and methods presented herein provide for readily configurable high voltage electrical energy generation. For example, a high voltage electrical energy generation system may include an AC power supply configured with an inductor to transfer AC electrical energy. In this regard, the system may also include a first receptor stage that includes an inductor for inductively coupling to the inductor of the AC power supply to receive the AC electrical energy. Similarly, a second receptor stage may inductively couple to the inductor of the AC power supply as well as to the inductor of the first receptor stage to receive the AC electrical energy, with each receptor being configured as a stackable plate. Each receptor stage may include a rectifier that converts the AC electrical energy to DC electrical energy. The rectifiers may be coupled together via a DC to DC connection provide a DC bias.Type: GrantFiled: June 4, 2008Date of Patent: September 25, 2012Assignee: Applied Energetics, IncInventors: Rudolf H.

Patent number: 6850071Abstract: The method and apparatus of the present invention are useful for the monitoring of the electrical signals within an internal combustion spark plug circuit and the killing of a spark plug within that circuit. The invention essentially consists of connecting a transformer to the high voltage side of the spark plug circuit. Through the use of impedance and inductance, the present invention can either produce a low voltage replica of the waveform of the high voltage electrical signal which is directed to a spark plug or can effectively prohibit that spark plug from firing by short circuiting the low voltage side of the transformer of the device.Type: GrantFiled: August 28, 2003Date of Patent: February 1, 2005Assignee: Automotive Test Solutions, Inc.Inventors: Neal R. Pederson, Bernie C. Thompson, James M. Potter

Patent number: 6377004Abstract: A thin vacuum valve for particle accelerator beam lines comprising of a frame, a slide, a shaft, a first clamp, and preferably a second clamp, which is easily constructed from highly electrically conductive material and presents substantially smooth, flat surfaces towards adjacent particle accelerator component. The frame has first and second surfaces respectively facing toward the two adjacent particle accelerator system components, the first surface including a slide slot. A frame orifice extends through the frame between the first and second surfaces, preferably at the slide slot, and is positioned and sized on the frame to permit passage of a particle beam generated by the particle accelerator system along a beam line The slide is housed substantially within the slide slot and is movable between a first position and a second position along a slide axis. In the first position, the slide permits a particle beam to pass through the slide orifice and through the frame orifice along the beam line.Type: GrantFiled: November 2, 1999Date of Patent: April 23, 2002Assignee: International Isotopes, Inc.Inventors: Floyd Del McDaniel, James M.

Patent number: 6201355Abstract: The apparatus is a gas filled ultraviolet generating lamp for use as a liquid purifier. The lamp is powred by high voltage AC, but has no metallic electrodes within or in contact with the gas enclosure which is constructed as two concentric quartz cylinders sealed together at their ends with the gas fill between the cylinders. Cooling liquid is pumped through the volume inside the inner quartz cylinder where an electrically conductive pipe spaced from the inner cylinder is used to supply the cooling liquid and act as the high voltage electrode. The gas enclosure is enclosed within but spaced from a metal housing which is connected to operate as the ground electrode of the circuit and through which the treated fluid flows. Thus, the electrical circuit is from the central pipe, and through the cooling liquid, the gas enclosure, the treated liquid on the outside of the outer quartz cylinder, and to the housing.Type: GrantFiled: November 8, 1999Date of Patent: March 13, 2001Assignee: Triton Thalassic Technologies, Inc.Inventors: Gary L.

Patent number: 5315120Abstract: A radio-frequency quadrupole which includes four, extruded, identical cross-section, elongate structural components, each of which lacks any longitudinally extending plane of bilateral assembly. Joinder of these components to form a quadrupole body results in an overall axial cross-sectional configuration which has an infinite number of claims of inverted bilateral symmetry extending in all radial directions relative to the long axis of that body. Coolant-carrying boreholes extend longitudinally throughout each component with precise location and proper longitudinal-axial-parallelism.Type: GrantFiled: June 7, 1993Date of Patent: May 24, 1994Assignee: AccSys Technology, Inc.Inventor: James M.
