Fat Man - Wikipedia
In November 1945, the Army Air Forces asked Los Alamos for 200 Fat Man bombs, but there were only two sets of plutonium cores and high-explosive assemblies at the time. The Army Air Forces wanted improvements to the design to make it easier to manufacture, assemble, handle, transport, and stockpile.
The Chilling Story of The 'Demon Core' And The Scientists …
Apr 26, 2018 · New protocols meant an end to 'hands on' criticality experiments, with scientists forced to use remote control machinery to manipulate radioactive cores at a distance of hundreds of metres. They also stopped calling the plutonium core 'Rufus'. From then on, it was known only as the 'demon core'.
Nuclear weapon design - Wikipedia
Trinity- Gadget was the first ever pure-fission nuclear device to be detonated, with an estimated yield of 25 kilotons. The first task of a nuclear weapon design is to rapidly assemble a supercritical mass of fissile (weapon grade) uranium or plutonium.
Trinity (nuclear test) - Wikipedia
Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT [a] (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan ...

Jun 5, 2014 · The first human plutonium injection occurred on April 10, 1945 when a 55-year old patient at the Manhattan Project Hospital in Oak Ridge was injected with 4.7 micrograms of plutonium in the chemical form of the +4 citrate salt.
The Bombing of Nagasaki, August 9, 1945
The bombing of the Japanese city of Nagasaki with the Fat Man plutonium bomb device on August 9, 1945, caused terrible human devastation and helped end World War II.
Science Behind the Atom Bomb - Nuclear Museum
Jun 5, 2014 · Physicist Seth Neddermeyer at Los Alamos constructed a design for the plutonium bomb that used conventional explosives around a central plutonium mass to quickly squeeze and consolidate the plutonium, increasing the pressure and density of the substance.
Atomic bomb | History, Properties, Proliferation, & Facts
Oct 11, 2024 · atomic bomb, weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of a heavy element such as plutonium or uranium.
Little Boy and Fat Man - Nuclear Museum
Jul 23, 2014 · “Fat Man” was the second plutonium, implosion-type bomb. The first was the “Gadget” detonated at the Trinity site on July 16, 1945. In the implosion-type device, a core of sub-critical plutonium is surrounded by several thousand pounds of high-explosive designed in such a way that the explosive force of the HE is directed inwards ...
Fat Man | Definition, Nagasaki, Description, Plutonium,
Oct 25, 2024 · Fat Man was a plutonium implosion-type bomb. It had a spherical core of plutonium-239 surrounded by high explosives, the force of which pushed inward rather than outward on detonation.
