under the contracts and damages to be charged against money held by SFO onthejobs, all required extensive research.

TEST OPERATIONS Prior to establishment of the Office of Test Operations in 1951, staff functions for full-scale weapons tests were performedby individuals on the SFOOstaff or by contractors. 1951. Two continental and one overseas test series were conducted during calendar year By completion of the second Nevada series, Buster-Jangle, it had become obvious that the increasing frequency, scope, complexity, and number of participants had ex- ceeded the staff resources provided. The Office of Test Operations was organized to provide staff supervision for full- scale weapons tests in collaboration with the Scientific Test Director and others con- cerned, The office was established in January 1952, and staffing was completed in April 1952. Assisting the Director and Deputy Director are one representative each for over- seas and continental tests, and for administration. There is a single secretary. The office administers contracts and inter-agency agreements for test support common to both proving grounds. The CPFF contract with Edgerton, Germeshausen and Grier and the agreement with Naval Reserve Laboratory fall in this category. In fulfilling directives from DMA and the requirements of scientific laboratories, extensive liaison and coordination are required between the Los Alamos Scientific Laboratory, the University of California Radiation Laboratory, and the Department of Defense. Arrangements are also made by this office for participation by other Government agencies, such as United States Weather Bureau, United States Public Health Service, and Federal Civil Defense Administration, all of which contribute significantly to the test program. Within the limits of SFO responsibilities, supporting military groups are obtained as are specialists in certain instances from other Operations Offices, such as Oak Ridge and New York. The Director has served as Assistant Test Manager of continental tests, and will serve as Commander, Task Group 7.5, on Castle. Some staff positions in the test or- ganizations are filled by OTO. 20.
