who designed the staged radiation implosion model of the hydrogen bomb
Radiation implosion Radiation implosion was first developed by Klaus Fuchs and John von Neumann in the United States, as part of their work on the original "Classical Super" hydrogen bomb design. Their work resulted in a secret patent filed in 1946, and later given to the USSR by Fuchs as part of his nuclear espionage. However, their scheme was not the same as used in the final hydrogen bomb design, and neither the American nor the Soviet programs were able to make use of it directly in developing the hydrogen bomb (its value would become apparent only after the fact). A modified version of the Fuchs-von Neumann scheme was incorporated into the "George" shot of Operation Greenhouse.[1]
Tsar Bomba Tsar Bomba (Russian: Царь-бомба; "Tsar-bomb") was the Western nickname for the Soviet RDS-220 hydrogen bomb (code name Ivan[3] or Vanya), the most powerful nuclear weapon ever detonated. Its test on 30 October 1961 remains the most powerful man-made explosion in history. It was also referred to as Kuzkina mat (Russian: Кузькина мать; "Kuzma's mother"),[4] possibly referring to Nikita Khrushchev's promise to show the United States a Kuzkina mat (an idiom roughly translating to "We'll show you!") at a 1960 session of United Nations General Assembly.[5][6]
