The final organization is shown iv Fig. 3.1. It includes task units for the University of California Radiation Laboratory programs, for ° , UCRL device assembly, and for the Department of Defense programs. These are changes from the Ivy organization. In order to free himself for other urgent commitments, the Task Group Commander did not personally take charge of the Firing Party Task Unit. This proved to be a worth-while change from the previous practice. At midnight Washington time, January 31, 1953, Joint Task Force 132 became Joint Task Force SEVEN and Task Group 132.1 became Task Group 7.1. established. On March 4, 1953, Task Group 7.5, AEC Base Facilities, was During 1953, UCRL organized, staffed, and established L-Division at Livermore, California. Relationships between the L-Division group and Headquarters, Task Group 7.1, were very close during this period. For most of the time UCRL had a liaison representative in residence at Los Alamos, and visits were constantly exchanged between members of the two organizations. In order to support UCRL overseas and to train personnel for future overseas tests, L-Division integrated personnel into the Task Group 7.1 J-1, J 3, and J-6 staff sections and filled billets in’ those sections overseas. |, Since the principal function of the Task Force and most of the Task Groups was to support the scientific effort, most of the overall planning depended on the plans of Task Group 7.1. Therefore, command relationships differed somewhat from the normal military pattern. Figure 3.2 shows the Joint Task Force SEVEN organization and some of the major command relationships personnel of Task Group 7.1. involved, and Table 3.1 shows the key CJTF SEVEN coordinated the activities of Task Groups 7.1 and 7.5 through his Scientific Director, in accordance yh = 5
