6, THE NEVADA TEST ORGANIZATION All tests in Nevada are conducted by the Nevada Test Organization, which is made up of representatives of the Atomic Energy Commission, the Department of Defense, the Federal Civil Defense Administration, other government agencies, government contractors, research and educational institutions, and private industrial firms. (See charts at the back of this booklet.) An AEC Test Manager has had over-all field management of each series conducted in Nevada. His task is to plan operations, to coordinate the activities of all the units within the Test Organization, to exercise operational control at the Test Site, and to prepare and execute operations as scheduled. His is the final decision as to whether operational conditions will permit a shot to be fired, or whether a postponement is required. Since the fall of 1951, a Deputy for Military Matters has served under the Test Manager. He represents the Commander, Field Coxmand, Armed Forces Special Weapons Project, sand provides staff assistance to the Test Manager on matters involving Department of Defense participation and support. He also performs liaison between AEC and DOD agencies on policy and operational matters, and is responsible for military administrative matters such as management of military property and funds. Prior to 1957, the Test Director for each series had been a representative of the Los Alamos Scientific Laboratory. For the Sunmer 1957 series, a staff member of the University of California Radiation Laboratory at Livermore was appointed to the position, reflecting the growing participation by the Livermore laboratory in test. cperations. The Test Director is responsible for over-all coordination and scientific support for the entire scientific test program; for planning, coordinating and conducting the tests of experimental weapons and devices; and for positioning, arming and detonating the test devices.
