development, testing, production and storage of atomic weapons. K, F. Hertford is Manager of Albuquerque Operations, and main- tains his headquarters in the Albuquerque Operations Office (ALOO) in Albuquerque, New Mexico. In addition to the ALOO headquarters, Albuquerque Operations has eight area offices and three branch offices supervising the operation by contractors of a complex of laboratories, test sites, and industrial facilities reaching Yrom the Atlantic seaboard to Eniwetok Atoll in the far Pacific. The test sites administered by Albuquerque Operations include the Eniwetok Proving Ground in the Marshall Islands and the Nevada Test Site. Los Alamos Scientific Laboratory (LASL) was established at Los Alamos, New Mexico, early in 1943 for the specific purpose of developing an atomic bomb. Los Alamos scientists supervised the _ test detonation in July, 1945, at the Trinity site in New Mexico of the world's first nuclear weapon. The Laboratory's current weapons assignment essentially is to conceive, test and develop the nuclear components of atomic weapons. Its Director is Dr. Norris L. Bradbury... tt is operated by the University of California.. . University of California Radiation Laboratory (Livermore branch) was established as a second AEC weapons laboratory at Livermore, California, in 1952. The Livermore laboratory's responsibilities are essentially parallel to those of the Los Alamos laboratory. Livermore weapon designs first were tested in Nevada in 1953, and they have been tested in each continental and Pacific series since. The contract under which the University of California Radiation Laboratory performs work for the AEC is administered by the Commission's San Francisco Operations Office. Director of the Livermore facility of the UCRL is Dr. Herbert L. York. Sandia Laboratory at Albuquerque, New Mexico, is the AEC's other weapons laboratory. It was established in 1946 as a branch of the Los Alamos Scientific Laboratory, but in 1949 it assumed its present identity as a. full-fledged weapons research institution, and since then has been operated by the Sandia Corporation, a nonprofit subsidiary of Western Electric. Sandia Laboratory's role is to conceive, design, test and develop the non-nuclear phases of atomic weapons, and to do other work in related fields. In 1956 a Livermore -Branch of the Laboratory was established to provide closer support to developmental work of the UCRL Livermore facility. Sandia Corporation also operates ballistic test facilities for the AEC at Salton Sea Test Base, California, and at the Tonopah Ballistics Range near Tonopah, Nevada. President of the Sandia Corporation is James W. McRae. ~ 25 -
