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...

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...

The United States is now in a better position than at any time in the past to maintain a safe and effective nuclear weapons stockpile without testing and to monitor clandestine nuclear testing abroad, says a new report from the National Research Council. The report, requested by the Office of the Vice President and the White House Office of Science and Technology Policy, reviews and updates a 2002 study that examined the technical concerns raised about the Comprehensive Nuclear Test Ban...

LIVERMORE, Calif. (AP) -- Ed Moses talks of the "grand challenge" that has consumed him for the past five years, comparing it to trying to hit the strike zone with a baseball from 350 miles away or tossing a dime into a parking meter from 40 miles. "That's the precision we have to have," says Moses, the director of a high-energy physics adventure to produce the world's most powerful laser - one that scientists hope will create in a laboratory the energy found at the center of the sun. In a...

Word of the Day
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
