Scientists at the California-based lab repeated the fusion ignition breakthrough in an experiment in the National Ignition Facility (NIF) on July 30 that produced a higher energy yield than in ...
Fusion is the process through which the sun makes energy. The sun’s core is the ideal high-pressure, high-temperature environment for hydrogen atoms to fuse into helium; replicating those ...
The U.S. Department of Energy officially announced a breakthrough in nuclear fusion on Tuesday that puts the world one step closer to harnessing an abundant energy source free from carbon ...
The breakthrough will not immediately open the floodgates to clean power in American homes, but it is a powerful symbol that the fundamental scientific concepts underlying the promise of fusion ...
A NIF fusion shot on September 27, 2013, produced more energy than was absorbed by the deuterium–tritium fuel. [120] This has been confused with having reached "scientific breakeven", [121] [122] defined as the fusion energy exceeding the laser input energy. [123] Using this definition gives 14.4 kJ out and 1.8 MJ in, a ratio of 0.008. [120]
The first Soviet fusion bomb test, RDS-6s, American codename "Joe 4", demonstrated the first fission/fusion/fission "layercake" design, limited below the megaton range, with less than 20% of the yield coming directly from fusion. It was quickly superseded by the Teller-Ulam design. This was the first aerial drop of a fusion weapon.
DIII-D is a tokamak that has been operated since the late 1980s by General Atomics (GA) in San Diego, California, for the United States Department of Energy.The DIII-D National Fusion Facility is part of the ongoing effort to achieve magnetically confined fusion.
Still, it had attained an important breakthrough that December day. As the news trickled out, fusion fever spread around the world; U.S. Energy Secretary Jennifer Granholm described it as the most ...
