Most people know that diamond is one of the hardest solids on Earth, so strong that it can easily cut through glass and steel. Surprisingly, very little is known about the strength of diamond at extreme conditions. But new research by Lawrence Livermore National Laboratory scientists shows that diamond becomes even stronger during rapid compression. Using the Janus laser at LLNL and the Omega laser at the University of Rochester, Livermore scientists and Rochester and UC Berkeley colleagues...

Scientists demonstrate strong laser radiation-matter coupling with intense 2.1kJ, 15ps laser pulses critical for creating and diagnosing advanced fusion plasmas A new generation of high-energy (>kJ) petawatt (HEPW) lasers is being constructed worldwide to study high intensity laser matter interactions, including fast ignition. Fast ignition is a laser-based technique for heating and igniting deuterium and tritium fuel to fusion temperatures in a two-step process. In the first phase, laser...

Critical to understanding inertial confinement fusion For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers to high enough pressure and temperature to initiate fusion burn. To achieve fusion scientists must put as much laser energy on target as possible, a task complicated by energy loss due to laser backscatter, or reflection. Fusion is the basic...

Owners of an upstate New York human-potential retreat center's new building say it may become the world's first living building. The $3.5 million Omega Center for Sustainable Living at the Omega Institute for Holistic Studies in Rhinebeck, N.Y., goes way beyond green, Omega said. The one-story, 6,250-square-foot building, inaugurated Thursday, takes a whole systems approach and uses integrative design, Omega Chief Executive Officer Skip Backus said. Right now, most people think of 'green' as...

On Friday, a U.S. weapons lab unveiled a super laser with the power to burn as hot as a star. The National Ignition Facility's main purpose for the tool is to gauge the reliability and safety of the U.S. nuclear-weapons arsenal, but scientists say it could deliver breakthroughs in safe fusion power. "We have invented the world's largest laser system," actor-turned-governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands including state and national officials. "We...

California Gov. Arnold Schwarzenegger Friday dedicated the world's largest laser system in Livermore, calling it a gateway to new energy sources. The sprawling National Ignition Facility at the Lawrence Livermore National Laboratory east of San Francisco has been 12 years in the making and is designed to further research into fusion energy. NIF has the potential to revolutionize our energy system -- teaching us a new way to harness the energy of the sun to power our cars and homes,...

The U.S. Department of Energy says the National Nuclear Security Administration has certified the completion of the world's largest laser. Located at the Lawrence Livermore National Laboratory's National Ignition Facility in California, the laser is expected to allow scientists to achieve fusion ignition in the laboratory, obtaining more energy from the target than is provided by the laser. Completion of the National Ignition Facility is a true milestone that will make America safer and more...

The U.S. construction of the National Ignition Facility (NIF) is complete and researchers are preparing to start the first experiments aimed at recreating conditions at the heart of our Sun, BBC News reported. Scientists hope the experiments will demonstrate the feasibility of nuclear fusion, a process that could offer abundant clean energy. They will begin by focusing 192 giant laser beams on a tiny pellet of hydrogen fuel, in hopes they can show that more energy can be extracted from the...

Scientists in California say they're trying to replicate the power of the sun by firing laser beams at a tiny pellet of hydrogen. Physicists at the National Ignition Facility in Livermore say the nuclear fusion experiments may offer the world a clean source of energy, The Times of London reported Sunday. The hydrogen pellet will be hit with 192 laser beams capable of generating 500 trillion watts -- 1,000 times the power of the U.S. national grid, said the scientists. We hope the ignition...

Research that has provided a deeper understanding into the center of planets could also provide the way forward in the world's quest for cleaner energy. An international team of scientists, led by the University of Oxford, working alongside researchers at the Science and Technology Facilities Council's (STFC) Central Laser Facility, has gained a deeper insight into the hot, dense matter found at the center of planets and as a result, has provided further understanding into controlled...
