McMillan took an early interest in this, watching tests of this concept conducted by Seth Neddermeyer. The alternative was to build an implosion-type nuclear weapon. The plutonium gun, codenamed Thin Man, needed a muzzle velocity of at least 3,000 feet (910 m) per second, which they hoped to achieve with a modified Navy 3-inch antiaircraft gun. On July 16, 1945, he was present at the Trinity nuclear test, when the first implosion bomb was successfully detonated.Īs the laboratory took shape, McMillan became deputy head of the gun-type nuclear weapon effort under Navy Captain William S. McMillan was also involved with the implosion as the head of the G-3 Group within the G (Gadget) Division, which was responsible for obtaining measurements and timings on implosion, and served as the laboratory's liaison with Project Camel, the aerial test program being carried out by Caltech. This being the case, Thin Man was replaced by a new, scaled-back design called Little Boy. McMillan remained in charge of the gun-type weapon, which would now be used only with uranium-235. In July 1944, Oppenheimer reorganised the laboratory to make an all-out effort on implosion. Segrè's group had tested samples of plutonium bred in the Manhattan Project's nuclear reactors and found that it contained quantities of plutonium-240, an isotope that caused spontaneous fission, making Thin Man impractical. McMillan heard disturbing news in April 1944, and drove out to Pajarito Canyon to confer with Segrè. So, how much is Edwin McMillan worth at the age of 84 years old?
