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. It was manufactured in 1945 by the Manhattan Project, the U.S. nuclear weapon development effort during World War II.

2024年4月3日 · The fate of the demon core, after its brief yet impactful history, was to be melted down and recycled into new cores for testing. Following the second accident and the death of Louis Slotin, the laboratory instituted a change in how it approached nuclear safety.

The Ultimate Fate of the Demon Core. After its tragic involvement in the criticality accidents that claimed the lives of Harry Daghlian and Louis Slotin, the demon core faced an uncertain fate. The core was left behind at Los Alamos National Laboratory. It had been slated for use in an atomic bomb as part of the Operation Crossroads nuclear tests.

It was August 13, 1945, and the 'demon core' was poised, waiting to be unleashed onto a stunned Japan still reeling in fresh chaos from the deadliest attacks anyone had ever seen. What happened to the nuclear bombs that weren't used?

2016年5月21日 · Louis Slotin, a Canadian physicist, was showing his colleagues how to bring the exposed core of a nuclear weapon nearly to the point of criticality, a tricky operation known as “tickling the ...

It was August 13, 1945, and the ‘demon core’ was poised, waiting to be unleashed onto a stunned Japan still reeling in fresh chaos from the deadliest attacks anyone had ever seen. A week earlier, ‘Little Boy’ had detonated over Hiroshima, followed swiftly by ‘Fat Man’ in Nagasaki.

After Slotin’s death, the core was given a macabre nickname: the “demon core.” Wellerstein traces the fate of the demon core. Previously it been thought that the core was used in one of the nuclear tests at Operation Crossroads.

2016年5月23日 · Louis Slotin, a Canadian physicist, was showing his colleagues how to bring the exposed core of a nuclear weapon nearly to the point of criticality, a tricky operation known as “tickling the dragon’s tail.”

2020年11月24日 · However, the Demon Core would still result in a few fatal accidents. The first being on August 21, 1945, when a nuclear physicist, Harry Daghlian was doing research on it. While working with the Demon Core, Daghlian accidently dropped a block of Tungsten Carbide on the mass causing it to go super-critical.

2022年1月18日 · The Demon Core, consisting of two sub-critical masses of plutonium, was a component of the Fat Man atomic bomb. It gained its notorious reputation due to two separate criticality accidents that occurred during the Manhattan Project in the late 1940s.
