Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets by crushing diamond samples using the world's most powerful laser system, the National Ignition Facility. The research appears in the June 17 edition of the journal, Nature. Livermore, California (PRWEB) July 17, 2014 Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such...

Series Of Experiments Show Initial Gain In Fusion Fuel
2014-02-12 14:37:51

Breanna Bishop - Lawrence Livermore National Laboratory Ignition -- the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel -- has long been considered the "holy grail" of inertial confinement fusion science. A key step along the path to ignition is to have "fuel gains" greater than unity, where the energy generated through fusion reactions exceeds the amount of energy deposited into the fusion fuel. Though ignition remains the...

Nuclear Fusion Step Forward
2013-10-14 09:00:58

John P. Millis, PhD for redOrbit.com - Your Universe Online Much has been made of the energy crisis in recent years. Currently our dependence is predominantly on limited natural resources – coal, natural gas, oil, etc. Alternatives exist, of course, such as solar, wind, hydroelectric, and even nuclear. But each of these has significant drawbacks, whether that is cost, efficiency, or waste. The solution that everyone is looking to is nuclear fusion, where light atoms are compressed at...

Getting Close To Igniting A Self-sustained Fusion Reaction
2013-09-25 09:08:02

American Institute of Physics The dream of igniting a self-sustained fusion reaction with high yields of energy, a feat likened to creating a miniature star on Earth, is getting closer to becoming reality, according the authors of a new review article in the journal Physics of Plasmas. Researchers at the National Ignition Facility (NIF) engaged in a collaborative project led by the Department of Energy's Lawrence Livermore National Laboratory, report that while there is at least one...

Record Simulations Performed On Lawrence Livermore Supercomputer
2013-03-20 08:30:42

Lawrence Livermore National Laboratory Researchers at Lawrence Livermore National Laboratory have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world. Sequoia, based on IBM BlueGene/Q architecture, is the first machine to exceed one million computational cores. It also is No. 2 on the list of the world's fastest supercomputers, operating at 16.3 petaflops (16.3 quadrillion floating point operations per second). The simulations are...

Potential benefits of inertial fusion energy justify continued R&D; nationally coordinated program should wait until ignition is achieved The potential benefits of successful development of an inertial confinement fusion-based energy technology justify investment in fusion energy research and development as part of the long-term U.S. energy R&D portfolio, says a new report from the National Research Council. Although ignition of the fusion fuel has not yet been achieved, scientific...

Laser Facility Makes Historic 500 Terawatt Shot
2012-07-18 06:06:44

Lee Rannals for redOrbit.com - Your Universe Online If all Marty McFly needed was 1.21 gigawatts to travel through time, then one feat accomplished at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) would provide him enough fuel to travel back to the future 413,223 times. The team made a historic record-breaking laser shot after 15 years of work on July 15, delivering over 500 terawatts, or 500 trillion watts, of power. The amount of power generated by...

Models Help Define Exoplanet Structure
2012-02-02 04:28:37

Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state (EOS) of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors. Astronomers started detecting exoplanets...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
