| 20090285362 | Flash X-Ray Irradiator - An apparatus for Flash X-ray irradiation of material includes a Flash X-ray source comprised of an electron gun and an anode. The electron gun comprises a field emission cold cathode having an electrode emitting surface, and a grid for controlling electron flow from the cathode to the anode. The anode has an electron-receiving main surface and an X-ray emitting, oppositely facing main surface. The X-ray emitting surface emits X-radiation into an irradiation volume. The X-ray emitting surface of the anode has orthogonally oriented first and second dimensions of greater than 2 millimeters each. A high voltage pulse power supply powers the Flash X-ray source. The electron gun, anode and high voltage pulse power supply are so constructed as to create sufficient X-radiation in said irradiation volume to achieve a desired level of irradiation of material in said volume. | 11-19-2009 |
| 20100097734 | Method and Apparatus for Protecting Power Systems from Extraordinary Electromagnetic Pulses - One form of the invention provides a method and apparatus for preventing an extraordinary electromagnetic pulse from reaching and rendering inoperative an electrical component of an electrical power system, wherein the component is located in a conductive path of the system that receives the pulse. The method and apparatus comprises the steps or means for detecting the presence of the pulse in the conductive path prior to the pulse reaching and rendering inoperative the electrical component. The pulse is diverted around the electrical component with a low inductance, high current capacity circuit relative to the electrical component before the pulse can reach and render the electrical component inoperative. The foregoing invention may beneficially utilize a high-speed current shunt comprising a flat conductive metal strap having a defined current-measuring region, a tapered parallel-plate transmission-line matching transformer attached to the current-measuring region and an output via a coaxial cable. | 04-22-2010 |
