Nearly 20 year ago, a group of researchers at Lawrence Livermore National Laboratory proposed a hole boring process that would serve as the original scheme for fast ignition. Today, researchers are pushing this research ahead into new regimes.
Lawrence Livermore National Laboratory's JASPER gas gun has fired its 100th shot. JASPER (the Joint Actinide Shock Physics Experimental Research) is a key scientific tool for the National Nuclear Security Administrations Stockpile Stewardship Program and its experiments have enabled scientists to understand important properties and behaviors of plutonium and other special nuclear materials without conducting underground nuclear tests.
After four years of work in his parent’s garage, 14-year-old Taylor Wilson built his first successful fusion reactor. Now 18 and old enough to be actually be a student at the university where he shares a laboratory, Wilson is chasing research projects of many kinds and is still fascinated by the science of the atom.
Borrowing a technology used to improve the effectiveness of drugs, scientists at the University of Michigan and Lawrence Livermore National Laboratory are reporting discovery of a new explosive more powerful than the current state-of-the-art explosive used by the military, and just as safe for personnel to handle.
Researchers at Lawrence Berkeley National Laboratory's Molecular Foundry developed a first-of-its-kind model for providing a comprehensive description of the way in which molecular bonds form and rupture. This model enables researchers to predict the "binding free energy" of a given molecular system, a key to predicting how that molecule will interact with other molecules.
Lawrence Livermore National Laboratory researchers have discovered a new method to independently control ionic and electronic conductivities in certain solids. The method, which uses tailored acceptor-donor co-doping to bind charged native vacancies and selectively modulate ionic but not electronic conductivity, was developed by using first-principles materials simulations.
A team of researchers studying the fundamental properties of the actinide elements has significantly advanced the understanding of the electronic structure of elements that have electrons occupying f-orbitals.
Lawrence Livermore National Laboratory researchers have developed a new capacitive desalination technique that could ultimately lower the cost and time of desalinating seawater. The technique, called flow-through electrode capacitive desalination, uses porous carbon materials with a hierarchical pore structure, which allows the saltwater to easily flow through the electrodes themselves.
Fifteen years of work by the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) team paid off on July 5 with a historic record-breaking laser shot. The NIF laser system of 192 beams delivered more than 500 TW of peak power and 1.85 MJ of ultraviolet laser light to its target.
With the help of intense coherent X-ray pulses from the Linac Coherent Light Source free-electron laser, Lawrence Livermore National Laboratory researchers and international collaborators have, for the first time, peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs—usually without a trace.
Researchers at IBM and Lawrence Livermore National Laboratory announced that they are broadening their nearly 20-year collaboration in high-performance computing by joining forces to work with industrial partners to help boost their competitiveness in the global economy.
Modern research tools like supercomputers, particle colliders, and telescopes are generating so much data, so quickly, many scientists fear that soon they will not be able to keep up with the deluge. A team of computer researchers from universities and national laboratories are fighting to keep up, and have recently developed a tool that is able to query a massive 32 TB dataset in just 3 secs.
The U.S. Department of Energy's Heavy Ion Fusion Science Virtual National Laboratory has recently completed a new accelerator designed to study an alternate approach to inertial fusion energy. Housed at Lawrence Berkeley National Laboratory, NDCX-II is a compact machine designed to produce a high-quality, dense beam that can rapidly deliver a powerful punch to a solid target.
The National Nuclear Security Administration (NNSA) announced that a supercomputer called Sequoia at Lawrence Livermore National Laboratory was ranked the world's most powerful computing system. Clocking in at 16.32 sustained petaflops, Sequoia earned the No. 1 ranking on the industry standard Top500 list of the world's fastest supercomputers.
Scheduled for launch this week from Kwajalein Atoll in the Marshall Islands, the Nuclear Spectroscopic Telescope Array (or NuSTAR), is the first focusing, high energy X-ray satellite to be launched from NASA. Hundreds of times more sensitive than any previous hard X-ray instrument, it will allow researchers to take a census of black holes.
New research by a team of Lawrence Livermore National Laboratory scientists and international collaborators shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.
Lawrence Livermore National Laboratory researchers have for the first time identified a precise measurement of the amount of radiation damage that will occur in any given material. With a full understanding of the early stages of the radiation damage process, researchers are provided with better knowledge and tools to manipulate materials to our advantage.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail. Because international treaties forbid the detonation of nuclear test weapons, tools that can accurately depict an explosion are becoming critical for national defense.
The International Union of Pure and Applied Chemistry officially approved new names for elements 114 and 116, the latest heavy elements to be added to the periodic table. Scientists of the Lawrence Livermore National Laboratory-Dubna collaboration proposed the names as Flerovium for element 114, with the symbol Fl, and Livermorium for element 116, with the symbol Lv, late last year.
The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.
In experiments at SLAC National Accelerator Laboratory, a powerful X-ray laser blasted solid carbon crystals into a liquid and plasma even faster than expected, raising new questions about how these intense beams interact with matter. The tests took place at the Linac Coherent Light Source, or LCLS, using a pioneering technique to simultaneously blast and probe samples of graphite, a pure form of carbon.
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford University, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma.
The just-completed NDCX-II, the second generation Neutralized Drift Compression Experiment at the Lawrence Berkeley National Laboratory, is an unusual special-purpose particle accelerator built by the U.S. Department of Energy's Heavy Ion Fusion Science Virtual National Laboratory. The accelerator is a compact machine designed to produce a high-quality, dense beam that can rapidly deliver a powerful punch to a solid target.
A clear change in salinity has been detected in the world's oceans, signaling shifts and acceleration in the global rainfall and evaporation cycle tied directly to climate change, according to a recently published paper.
Lawrence Livermore National Laboratory has licensed its microbial detection array technology to a St. Louis, Mo.-based company, MOgene LC, a supplier of DNA microarrays and instruments. Known formally as the Lawrence Livermore Microbial Detection Array (LLMDA), the technology could enable professionals to detect within 24 hrs any virus or bacteria that has been sequenced and included among the array's probes.
