The START Tokamak fusion experiment begins in Culham. The experiment would eventually achieve a record beta (plasma pressure compared to magnetic field pressure) of 40% using a neutral beam injector. It was the first design that adapted the conventional toroidal fusion experiments into a tighter spherical design.
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.
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 ...
Toroidal machines can be axially symmetric, like the tokamak and the reversed field pinch (RFP), or asymmetric, like the stellarator.The additional degree of freedom gained by giving up toroidal symmetry might ultimately be usable to produce better confinement, but the cost is complexity in the engineering, the theory, and the experimental diagnostics.
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 ...
The Joint European Torus (JET) was a magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK. Based on a tokamak design, the fusion research facility was a joint European project with the main purpose of opening the way to future nuclear fusion grid energy. At the time of its design JET was ...
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 ...
