Apparatus to measure the decay of the free neutron. The experiment was designed by Luis Alvarez and was built and tested by Cornelius Tobias for his doctoral thesis in 1941. The project was stopped when the 37-inch cyclotron was converted to isotope separation. Photo taken May 2, 1941. Morgue 1946-8 (P-16); Cooksey 454 [Photographer: Donald Cooksey]

U.S. National Archives

The objects in this collection are from The U.S. National Archives. The U.S. National Archives and Records Administration (NARA) was established in 1934 by President Franklin Roosevelt. NARA keeps those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.

Disclaimer: A work of the U.S. National Archives is "a work prepared by an officer or employee" of the federal government "as part of that person's official duties." In general, under section 105 of the Copyright Act, such works are not entitled to domestic copyright protection under U.S. law and are therefore in the public domain.
