The tests were proposed by Nicholas Christofilos in an unpublished paper [3] of what was then the Livermore branch of the Lawrence Radiation Laboratory (now Lawrence Livermore National Laboratory) as a means to verify the Christofilos effect, which argued that high-altitude nuclear detonations would create a radiation belt in the extreme upper regions of the Earth's atmosphere.

According to the U.S. Government Project Officer's Interim Report on the Starfish Prime project: [3] Previous high-altitude nuclear tests: YUCCA, TEAK, and ORANGE, plus the three ARGUS shots were poorly instrumented and hastily executed. Despite thorough studies of the meager data, present models of these bursts are sketchy and tentative.
First nuclear weapons test, conducted as part of the Manhattan Project. Tested the Mark 3 Fat Man design. Crossroads: 1946 2: 2: 2: 21 42: First postwar test series. Sandstone: 1948 3: 3: 3: 18 to 49 104: The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the ...
Operation Sandstone was a series of nuclear weapon tests in 1948. It was the third series of American tests, following Trinity in 1945 and Crossroads in 1946, and preceding Ranger.
The RaLa Experiment, or RaLa, was a series of tests during and after the Manhattan Project designed to study the behavior of converging shock waves to achieve the spherical implosion necessary for compression of the plutonium pit of the nuclear weapon.
[2] [3] With an explosive yield of almost 5 megatons of TNT (21 PJ), the test was the largest underground explosion ever detonated by the United States. [ 4 ] Prior to the main five-megaton test in 1971, a 1 Mt (4.2 PJ) test took place on the island on October 2, 1969, for calibration purposes, and to ensure the subsequent Cannikin test could ...

Operation Roller Coaster [1] was a series of four nuclear tests conducted jointly by the United States and the United Kingdom in 1963, at the Nevada Test Site. [2] The tests did not involve the detonation of any nuclear weapons.
