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 first Ivy shot, codenamed Mike, was the first successful full-scale test of a multi-megaton thermonuclear weapon ("hydrogen bomb") using the Teller-Ulam design.Unlike later thermonuclear weapons, Mike used deuterium as its fusion fuel, maintained as a liquid by an expensive and cumbersome cryogenic system.
For two thermonuclear bombs for which the general size and primary characteristics are well understood, the Ivy Mike test bomb and the modern W-80 cruise missile warhead variant of the W-61 design, the radiation pressure was calculated to be 73 × 10 ^ 6 bar (7.3 TPa) for the Ivy Mike design and 1,400 × 10 ^ 6 bar (140 TPa) for the W-80.
Ivy Mike, the first full test of the Teller–Ulam design (a staged fusion bomb), with a yield of 10.4 megatons (November 1, 1952). The Teller–Ulam design is a technical concept behind modern thermonuclear weapons, also known as hydrogen bombs.
The first hydrogen bomb test, code-named Ivy Mike, occurred in late 1952 as part of Operation Ivy; it vaporized the islet of Elugelab, It also created two new elements : Fermium and Einsteinium. This test included B-17 Flying Fortress drones to fly through the radioactive cloud to test onboard samples. B-17 mother ships controlled the drones ...
Richard Lawrence Garwin (born April 19, 1928) is an American physicist, best known as the author of the first hydrogen bomb design. [1] [2]In 1978, Garwin was elected a member of the National Academy of Engineering for contributing to the application of the latest scientific discoveries to innovative practical engineering applications contributing to national security and economic growth.
The Ivy Mike test was the world's first "hydrogen bomb", producing a full-scale thermonuclear or fusion explosion. The Ivy Mike device used liquid deuterium, an isotope of hydrogen, making it a "wet" bomb.
The United States conducted six atomic tests before the Soviet Union developed their first atomic bomb and tested it on August 29, 1949. Neither country had very many atomic weapons to spare at first, and so testing was relatively infrequent (when the US used two weapons for Operation Crossroads in 1946, they were detonating over 20% of their ...
