The
IVY MIKE Test
At
seven o'clock in the morning, on November 1st,
1952, a man pushed a button on a control console on the USS Estes.
Fourteen minutes and 59.4 seconds later, a series of detonators
fired on the island of Eniwetok. The explosives compressed a hollow
sphere of uranium-plutonium alloy to a fraction of its former size;
at the same moment, a burst of neutrons from the initiator in the
sphere's center split a handful of atoms. Those fissioning atoms
released more neutrons, which split more atoms, releasing more
neutrons, building in a fraction of an instant to apocalyptic force.
The
superheated plasma began to push out from the boiling heart of the
primary – but the X-rays leapt ahead of it, bouncing down the
bomb casing to a refrigerated canister of cryogenic deuterium-tritium
wrapped in polyethylene. The X-rays evaporated the plastic, the
vapor pushing like rocket exhaust, compressing the D-T around a thin
rod of uranium, which began to fission itself, releasing still more
energy – and the fusion reaction ignited as deuterium + tritium
became helium-4 + neutron, a torrent of heat and light that shattered
the morning calm with the force of 10.4 million tons of TNT.
This was IVY MIKE, the United States' first test of a hydrogen
bomb, a weapon tapping nuclear fusion – the same process that
powers the stars.[Rh]
