A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors.. The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb.

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 impracticability of a gun-type bomb using plutonium was agreed at a meeting held on 17 July 1944. All gun-type work in the Manhattan Project was directed at the Little Boy enriched uranium gun design, and almost all of the research at the Los Alamos Laboratory was re-oriented around the problems of implosion for the Fat Man bomb.

A major accident might result in loss of life and severe health effects, and Groves was concerned that even a minor one could disrupt vital war production – particularly of aluminum – or require evacuation of the Manhattan Project's isotope separation plants. But spreading the Oak Ridge facilities over a larger area would involve the ...
On July 16, 1945, Manhattan Project staff conducted the first-ever nuclear test, which, according to the National Park Service, spread radioactive fallout over an area approximately 250 miles long ...
The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural (not isotopically enriched) uranium metal into plutonium-239 by neutron activation , as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear ...
