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 It was quickly superseded by the Teller-Ulam design.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.
Various authors have also put forth ways to organize all the fusion approaches that have been tested over the past 70+ years. This flow chart above groups the approaches into color coded families, these are: the Pinch Family (orange), The Mirror Family (red), Cusp Systems (violet), Tokamaks & Stellarators (Green), Plasma Structures (gray), Inertial Electrostatic Confinement (dark yellow ...
Matterhorn ultimately ended its involvement in the bomb field in 1954, becoming entirely devoted to the fusion power field. In 1958, this magnetic fusion research was declassified following the United Nations International Conference on the Peaceful Uses of Atomic Energy. This generated an influx of graduate students eager to learn the "new ...
This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons.
Nuclear fusion is a reaction in which two or more atomic nuclei (for example, nuclei of hydrogen isotopes deuterium and tritium), combine to form one or more atomic nuclei and neutrons. The difference in mass between the reactants and products is manifested as either the release or absorption of energy .
1936 Alexandru Proca formulates the relativistic quantum field equations for a massive vector meson of spin-1 as a basis for nuclear forces; 1936 Eugene Wigner develops the theory of neutron absorption by atomic nuclei

The DIII-D program achieved several milestones in fusion development, including the highest plasma β (ratio of plasma pressure to magnetic pressure) ever achieved at the time (early 1980s) and the highest neutron flux (fusion rate) ever achieved at the time (early 1990s). Major scientific discoveries include the validation of sheared flow ...
