Los Alamos National Laboratory

by Milton Beychok, Ro Thorpe and Daniel Mietchen


Los Alamos National Laboratory (LANL), located in Los Alamos, New Mexico, is one of several U.S. Department of Energy (DOE) national laboratories. It is noteworthy as the site where the first atomic weapon was developed under a heavy cloak of secrecy during World War II, and has been known variously as Site Y, Los Alamos Laboratory, and Los Alamos Scientific Laboratory. Today, it is recognized as one of the world's leading science and technology institutes.

Since 2006, LANL has been managed and operated by Los Alamos National Security, LLC (LANS).[1] LANL's self-stated mission is to ensure the safety, security, and reliability of the nation's nuclear deterrent.[2] Its research work serves to advance bioscience, chemistry, computer science, earth and environmental sciences, materials science, and physics disciplines.[3][4]

History

The Manhattan Project was the secret United States project conducted primarily during World War II with the participation of the United Kingdom and Canada that culminated in developing the world's first nuclear weapon, commonly referred to at that time as an atomic bomb.

The project was initiated in 1939 by U.S. President Franklin Delano Roosevelt after he received a letter from physicist Albert Einstein (drafted by fellow physicist Leó Szilárd) urging the study of nuclear fission for military purposes, under fears that Nazi Germany would be first to develop nuclear weapons. Roosevelt started a small investigation into the matter, which eventually became the massive Manhattan Project that employed more than 130,000 people at universities across the United States, the United Kingdom and Canada as well as at the three major design, development and production facilities: Los Alamos; Hanford, Washington; and Oak Ridge, Tennessee.
