Patent number: 11387007Abstract: An architecture for an inertial confinement fusion system is disclosed. The system includes a fusion chamber for producing neutrons from a fusion reaction, and a laser system in which lasers are arranged about a vacuum chamber to provide energy to the fusion chamber to initiate the fusion reaction. The beam paths between the lasers and the fusion chamber are configured to prevent neutrons from the fusion chamber from reaching the laser system at a level that would preclude human access to the laser system.Type: GrantFiled: November 8, 2011Date of Patent: July 12, 2022Assignee: Lawrence Livermore National Security, LLCInventors: Edward I. Moses, Jeffery F. Latkowski, Thomas M. Anklam, Mary L. Spaeth, Anthony Michael Dunne, Richard H. Sawicki, Robert J. Deri, Robin R. Miles, Andrew J. Bayramian, Kenneth R. Manes, Peter A.

Patent number: 10647064Abstract: An apparatus for use in a friction stir operation, such as friction stir welding (FSW) or friction stir processing (FSP). The apparatus may have a rotating tool adapted to be plunged into a material, where the material is susceptible to being softened by heating. The rotating tool may further be adapted to be advanced along a surface of the material. An optical energy generating subsystem may be used to heat a portion of the material using optical energy as the tool is advanced along the material.Type: GrantFiled: October 16, 2012Date of Patent: May 12, 2020Assignee: Lawrence Livermore National Security, LLCInventors: Joseph C. Farmer, Alexander M. Rubenchik, Raymond J. Beach, Robert J. Deri, Edward I. Moses, Bassem S. El-Dasher, Sarath K. Menon, Terry McNelley

Patent number: 9171646Abstract: A laser inertial-confinement fusion-fission energy power plant is described. The fusion-fission hybrid system uses inertial confinement fusion to produce neutrons from a fusion reaction of deuterium and tritium. The fusion neutrons drive a sub-critical blanket of fissile or fertile fuel. A coolant circulated through the fuel extracts heat from the fuel that is used to generate electricity. The inertial confinement fusion reaction can be implemented using central hot spot or fast ignition fusion, and direct or indirect drive. The fusion neutrons result in ultra-deep burn-up of the fuel in the fission blanket, thus enabling the burning of nuclear waste. Fuels include depleted uranium, natural uranium, enriched uranium, spent nuclear fuel, thorium, and weapons grade plutonium. LIFE engines can meet worldwide electricity needs in a safe and sustainable manner, while drastically shrinking the highly undesirable stockpiles of depleted uranium, spent nuclear fuel and excess weapons materials.Type: GrantFiled: September 30, 2008Date of Patent: October 27, 2015Assignee: Lawrence Livermore National Security, LLCInventors: Edward I.

Publication number: 20120057665Abstract: Using three tunable wavelengths on different cones of laser beams the energy transfer between beams can be tuned to redistribute the energy within the cones of beams most prone to backscatter instabilities. Using a third wavelength provides a greater level of control of the laser energy distribution and coupling in the hohlraum, to significantly reduce stimulated Raman scattering losses and increase the hohlraum radiation drive, yet maintain implosion symmetry.Type: ApplicationFiled: May 16, 2011Publication date: March 8, 2012Applicant: Lawrence Livermore National Security, LLCInventors: Edward I.

Patent number: 6260005Abstract: FALCON is a method for automatic multivariable optimization for arbitrary assessment criteria that can be applied to numerous fields where outcome simulation is combined with optimization and assessment criteria. A specific implementation of FALCON is for automatic radiation therapy treatment planning. In this application, FALCON implements dose calculations into the planning process and optimizes available beam delivery modifier parameters to determine the treatment plan that best meets clinical decision-making criteria. FALCON is described in the context of the optimization of external-beam radiation therapy and intensity modulated radiation therapy (IMRT), but the concepts could also be applied to internal (brachytherapy) radiotherapy. The radiation beams could consist of photons or any charged or uncharged particles. The concept of optimizing source distributions can be applied to complex radiography (e.g.Type: GrantFiled: February 9, 1999Date of Patent: July 10, 2001Assignee: The Regents of the University of CaliforniaInventors: Tser-Yuan Yang, Edward I.

Patent number: 6148272Abstract: A system and method is disclosed for radiation dose calculation within sub-volumes of a particle transport grid. In a first step of the method voxel volumes enclosing a first portion of the target mass are received. A second step in the method defines dosel volumes which enclose a second portion of the target mass and overlap the first portion. A third step in the method calculates common volumes between the dosel volumes and the voxel volumes. A fourth step in the method identifies locations in the target mass of energy deposits. And, a fifth step in the method calculates radiation doses received by the target mass within the dosel volumes.Type: GrantFiled: January 28, 1999Date of Patent: November 14, 2000Assignee: The Regents of the University of CaliforniaInventors: Paul M.

Patent number: 5337333Abstract: A method for formatting a laser beam pulse (20) using one or more delay loops (10). The delay loops (10) have a partially reflective beam splitter (12) and a plurality of highly reflective mirrors (14) arranged such that the laser beam pulse (20) enters into the delay loop (10) through the beam splitter (12) and circulates therein along a delay loop length (24) defined by the mirrors (14). As the laser beam pulse (20) circulates within the delay loop (10) a portion thereof is emitted upon each completed circuit when the laser beam pulse (20) strikes the beam splitter (12). The laser beam pulse (20) is thereby formatted into a plurality of sub-pulses (50, 52, 54 and 56). The delay loops (10) are used in combination to produce complex waveforms by combining the sub-pulses (50, 52, 54 and 56) using additive waveform synthesis.Type: GrantFiled: November 10, 1992Date of Patent: August 9, 1994Assignee: The United States of America as represented by the United States Department of EnergyInventors: Thomas P.

Patent number: 5168392Abstract: An improved dye laser amplifier is disclosed. The efficiency of the dye lr amplifier is increased significantly by increasing the power of a dye beam as it passes from an input window to an output window within the dye chamber, while maintaining the intensity of the dye beam constant.Type: GrantFiled: April 14, 1989Date of Patent: December 1, 1992Assignee: The United States of America as represented by the Department of EnergyInventor: Edward I.

Patent number: 5168400Abstract: A laser pulse stacking method is disclosed. A problem with the prior art has been the generation of a series of laser beam pulses where the outer and inner regions of the beams are generated so as to form radially non-synchronous pulses. Such pulses thus have a non-uniform cross-sectional area with respect to the outer and inner edges of the pulses. The present invention provides a solution by combining the temporally non-uniform pulses in a stacking effect to thus provide a more uniform temporal synchronism over the beam diameter.Type: GrantFiled: March 15, 1989Date of Patent: December 1, 1992Assignee: United States Department of EnergyInventor: Edward I.
