when was the first atomic bomb successfully tested July 16, 1945 what was it called? The code name given was Trinity who tested it? The United States Army where was it tested? In the Jornada del Muerto desert about southeast of Socorro, New Mexico. was this part of a larger project? Yes, the Manhattan Project. who headed this project? Major General Leslie Groves of the U.S. Army Corps of Engineers what was the purpose of this project? Research and development for nuclear weapons during World War II. name a few people who were involved in the original test Nuclear physicist Robert Oppenheimer how was the bomb detonated? UNANSWERABLE how much energy was generated? UNANSWERABLE were there any civilians involved? No, but civilians noticed the bright lights and huge explosion. what official notifications were sent out? The results of the test were conveyed to the Secretary of War Henry L. Stimson at the Potsdam Conference in Germany; was at once taken to Truman and Secretary of State James F. Byrnes. when were they sent out? UNANSWERABLE was there any fallout? Not much, but the heaviest fallout contamination outside the restricted test area was from the detonation point, on Chupadera Mesa. what is the condition of the site today? More than seventy years after the test, residual radiation at the site is about ten times higher than normal background radiation in the area.

Trinity (nuclear test) [SEP] Introduction
The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne. The test was of an implosion-design plutonium device, informally nicknamed "The Gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. The complexity of the design required a major effort from the Los Alamos Laboratory, and concerns about whether it would work led to a decision to conduct the first nuclear test. The test was planned and directed by Kenneth Bainbridge. Fears of a fizzle led to the construction of a steel containment vessel called Jumbo that could contain the plutonium, allowing it to be recovered, but Jumbo was not used.
