The first successful man-made fusion device was the boosted fission weapon tested in 1951 in the Greenhouse Item test. The first true fusion weapon was 1952's Ivy Mike, and the first practical example was 1954's Castle Bravo. In these devices, the energy released by a fission explosion compresses and heats the fuel, starting a fusion reaction.
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 It was quickly superseded by the Teller-Ulam design.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.
Ivy Mike was the codename given to the first full-scale [note 1] test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion. [ 1 ] [ 2 ] [ 3 ] Ivy Mike was detonated on November 1, 1952, by the United States on the island of Elugelab in Enewetak Atoll , in the now independent island nation ...
“Fusion, on the other hand, does not create any long-lived radioactive nuclear waste.” The waste byproduct of a fusion reaction is far less radioactive than in fission, and decays far more ...
First computer-optimized stellarator, first H-mode in a stellarator in 1992: Advanced Toroidal Facility (ATF) Shut down: 1984–1988 [68] 1988–1994: Torsatron: Oak Ridge: Oak Ridge National Laboratory: 2.1 m / 0.27 m: 2.0 T: First large American stellarator after Tokamak stampede, high-beta operation, >1h plasma operation: Compact Helical ...
Aug. 6—TRAVERSE CITY — Andrea "Annie" Kritcher designed an experiment that enables scientists to produce energy from nuclear fusion, which could result in a clean, limitless source of energy ...
The experiment at Lawrence Livermore National Laboratory in California actually used 100 times as much energy as it produced, and the day when nuclear fusion can power your laptop is far off, if ...
ZETA, short for Zero Energy Thermonuclear Assembly, was a major experiment in the early history of fusion power research. Based on the pinch plasma confinement technique, and built at the Atomic Energy Research Establishment in the United Kingdom, ZETA was larger and more powerful than any fusion machine in the world at that time.
