Sxperimental Techniques, The main objectives were to determine the fisaion ylelca and the relative thermonuclear and fission efficiencies in differert regions of the UCRL devices. Samples of the p27vicul2» G@ebris were collected after each test ance analyzed in the Zi. Gaseous samples weve collected on selected shots and were analyzed in the FA where necesséry for short-lived oroducts; the rest were sent to Livermore for enalveis. ot Airplane sampling was used on all tests; rocket sampling was attempted on several. Rockets, it was hoped, could be used to supplement and perhaps later obviate the need for manned aircraft. For the present at lease, sampling aircraft seem to be here to stay. bd. Results are shown in Table I. 2.3.2 4. Program 22, Reaction History. Experimental Techniques. Program 22 had the responsibility for Pinex as well as the reaction history measurements on all UCRL events. Devices were fired from four different locations with measurements as follows: 1. Tare, Bikini. The three events (Nutmeg, Hickory and Juniper) fired in the Zuni crater were extensively diagnosed. The coverag. included measurements of high explosive transit time, high ex- Cop; Ahy plosive pins, alpha vs time, boost time, boost temperature and 0/09 / sp, E LAW Re yield from Koala, Pinex, >litem where appli u 4 cable.
