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.
Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian and American theoretical physicist and chemical engineer who is known colloquially as "the father of the hydrogen bomb" and one of the creators of the Teller–Ulam design based on Stanisław Ulam's design.
On 1 November 1952, the Teller–Ulam configuration was tested at full scale in the "Ivy Mike" shot at an island in the Enewetak Atoll, with a yield of 10.4 Mt (44 PJ) (over 450 times more powerful than the bomb dropped on Nagasaki during World War II).
Stanisław Marcin Ulam (Polish: [sta'ɲiswaf 'mart͡ɕin 'ulam]; 13 April 1909 – 13 May 1984) was a Polish mathematician, nuclear physicist and computer scientist. He participated in the Manhattan Project, originated the Teller–Ulam design of thermonuclear weapons, discovered the concept of the cellular automaton, invented the Monte Carlo method of computation, and suggested nuclear pulse ...
He presented the idea to Edward Teller, who realized that radiation compression would be both faster and more efficient than mechanical shock. This combination of ideas, along with a fission "spark plug" embedded inside the fusion fuel, became what is known as the Teller–Ulam design for the hydrogen bomb.
The entire fusion fuel canister would need to be enveloped by fission energy, to both compress and heat it, as with the booster charge in a boosted primary. The design breakthrough came in January 1951, when Edward Teller and Stanislaw Ulam invented radiation implosion – for nearly three decades known publicly only as the Teller-Ulam H-bomb ...
The Ivy Mike shot of 1 November 1952, at Enewetak Atoll, was the first full test of a Teller-Ulam design staged hydrogen bomb, with a yield of 10 megatons. This was not a deployable weapon. With its full cryogenic equipment it weighed about 82 tons. [citation needed]
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.
