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 It was quickly superseded by the Teller-Ulam design.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 ...
The result was a scientific wonder, a feat that researchers had hoped to create in a laboratory since scientists first started bandying about the idea of using controlled nuclear fusion to produce ...
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 ...
When the news leaked that the U.S. Department of Energy was planning to announce that a federal laboratory had conducted the first-ever experiment with contained nuclear fusion that produced a net ...
