Louis Alexander Slotin (/ ˈ s l oʊ t ɪ n / SLOHT-in; [1] 1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who took part in the Manhattan Project.Born and raised in the North End of Winnipeg, Manitoba, Slotin earned both his Bachelor of Science and Master of Science degrees from the University of Manitoba, before obtaining his doctorate in physical chemistry at King's ...
The core of the device used in the Trinity Test at the Alamogordo Bombing and Gunnery Range in July did not have such a ring. [1] [2] The two physicists Harry Daghlian (center left) and Louis Slotin (center right) during the Trinity Test. Both died following supercritical accidents involving the "demon core."
While demonstrating his technique to visiting scientists at Los Alamos, Canadian physicist Louis Slotin manually assembled a critical mass of plutonium. A momentary slip of a screwdriver caused a prompt critical reaction. Slotin died on May 30 from massive radiation poisoning, with an estimated dose of 1,000 rads (rad), or 10 grays (Gy). Seven ...
Louis Slotin: 30 May 1946: The 35-year-old Canadian physicist and Manhattan Project scientist died as the result of an accident while performing an experiment called "tickling the dragon's tail" with a plutonium core which came to be known as the "demon core". His screwdriver slipped, exposing him to a fatal dose of radiation.
Louis Slotin, a colleague of Daghlian's, was killed in 1946 while performing criticality tests on the same plutonium core. [6] After these two incidents it became known as the " demon core ", [ 11 ] and all similar criticality experiments were halted until remote-controlled assembly devices were more fully developed and available.
When the screwdriver accidentally slipped, the cups closed around the plutonium, sending the assembly supercritical. Slotin quickly disassembled the device, likely sparing others in the room from lethal exposure, but Slotin himself died of radiation poisoning nine days later. The demon core was melted down and the material was reused in other ...
Louis Slotin. Dr. Louis Slotin, a physicist at the Los Alamos research center, was fatally injured during an experiment with a "subcritical nuclear assembly", a plutonium core and two halves of a beryllium sphere. The purpose was to measure the increase in radiation as the two hemispheres (which deflected neutrons back into the plutonium) were ...
This incident in which "Cochran" receives a fatal dose of radiation while assembling the Hiroshima bomb is a highly fictionalized reference to the deaths of Harry Daghlian and Louis Slotin, members of the Manhattan Project who died after contact with radioactive material on 21 August 1945 and 21 May 1946.
