CHAPTER 4 SUMMARY OF TASK UNIT ACTIVITIES 4.1 TASK UNIT 1, LASL PROGRAMS 4.1.1 Objectives af a. ea OO The function of TU-1 was to carry out experiments designed to measure certain properties of the. LASL-designed nuclear devices, These measurements were, in general, diagnostic; they were not performed to measure effects which depend mostly on yield but rather to give information on the performance of the devices to supplement or verify the theoretical calculations on the basis of which the devices were designed. 4.1.2 Techniques The techniques used to make the measurements are described in Chap. 2, Sec. 2.1. 4.1.3 Operations In the initial concept of the operation, it was intended that personnel would live ashore, and it was hoped that fall-out on the various stations would allow repeated use of the same buildings where necessary. However, provision was made for some groups to live aboard LCU’s if necessary for work on the close-in stations. All the initial setup work for the stations was done while the operation was land-based. After the first shot it was impossible to live ashore; therefore it was necessary to utilize shipboard space for personnel. Except for those groups which had madeprovision for living on LCU’s, this move increased the difficulties of the operation tremendously. Only the good cooperation received frum the various ships’ companies made it possible to have each shot ready on schedule, although the schedules were often changed owing to weather delays on previous shots. The helicopter shuttle system gave reliable transportation on short notice throughout the operation. It was essential to the success of an operation of this magnitude. The Rad-Safe problem was difficult but well handled, Afier a short transition period in the sucden change to a ship-based operation, there was little delay caused the experimenters by Rad-Safe requirements, and no TU-1 personnel received large or unexpected overdoses, 4.1.4 Results Results are given in Chap. 2, Sec, 2.1. 60
