The Christofilos effect, sometimes known as the Argus effect, refers to the entrapment of electrons from nuclear weapons in the Earth's magnetic field.It was first predicted in 1957 by Nicholas Christofilos, who suggested the effect had defensive potential in a nuclear war, with so many beta particles becoming trapped that warheads flying through the region would experience huge electrical ...
The warhead detonated with a yield of 1.45 Mt. This was the Starfish Prime event of nuclear test operation Dominic-Fishbowl; In the Dominic-Fishbowl series in 1962: Checkmate, Bluegill, Kingfish and Tightrope; The USA also conducted two live weapons test involving nuclear artillery including:
The United States completed six high-altitude nuclear tests in 1958, but the high-altitude tests of that year raised a number of questions. According to U.S. Government Report ADA955694 on the first successful test of the Fishbowl series, "Previous high-altitude nuclear tests: Teak, Orange, and Yucca, plus the three ARGUS shots were poorly instrumented and hastily executed.
The Lockheed X-17 was a three-stage solid-fuel research rocket to test the effects of high mach atmospheric reentry. The first stage of the X-17 carried the rocket to a height of 17 miles (27 km) before burning out. The rocket would then coast on momentum to about 100 miles (160 km) before nosing down for reentry.
Operation Teapot was a series of 14 nuclear test explosions conducted at the Nevada Test Site in the first half of 1955. It was preceded by Operation Castle , and followed by Operation Wigwam . Wigwam was, administratively, a part of Teapot , but it is usually treated as a class of its own.
The piece begins with the two nuclear explosions at Hiroshima and Nagasaki. The United States conducts several nuclear tests after the war. The Soviet Union and United Kingdom then gain nuclear weapons, increasing the number of explosions. [5] [6] The piece continues until it gets to Pakistan's first nuclear test in 1998. [7]
