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 ...

During an experiment on August 21, 1945, Daghlian was attempting to build a neutron reflector manually by stacking a set of 4.4-kilogram (9.7 lb) tungsten carbide bricks in an incremental fashion around a plutonium core. The purpose of the neutron reflector was to reduce the mass required for the plutonium core to attain criticality.
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 ...

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 Hanford Engineer Works (HEW) was a nuclear production complex in Benton County, Washington, established by the United States federal government in 1943 as part of the Manhattan Project during World War II. It built and operated the B Reactor, the first full-scale plutonium production reactor.
