temperature of the 88, total thermal output, and partit! of energy. The study of instrumentation techniques consisted in determining how best to gather these data in addition to diagnostic measurements of device performance. Of particular interest to the Department of Defense were the RF attenuation studies, which consisted mainly in recording signal strength from transmitters carried aloft by rockets to various position in time and space around the burst points. Most of the instrumentation was in stations positioned by rockets. Radiofrequency telemetry and recovery systems were used as means for gathering data. In addition, Program 32 provided the warheads and assisted in evaluating the fuzing and firing system. Program 34. Program 34 included ten Sandfa service projects, which were performed primarily for elements of Task Group 7.1. Project 34.1 measured the functioning of Zippers and HE transit time on 29 shots. Also, it tried an experimental early alpha system on 15 LASL shots. Project 34.2 supplied the device, fuze, and auxiliary systems used to detonate the DOD-sponsored, balloon-carried Yucca shot. Project 34.3 procured, assembled, and checked out the devices used in the underwater DOD shots, Umbrella and Wahoo. Project 34.4 measured microbarographic blast waves, primarily on Teak and Orange, but also on most of the other Hardtack shots. Project 34.5 provided the Zippers and auxtNary system for LASL and UCRL on 28 shots. Project 34.6 provided systematic support to UCRL. Project 34.7 studied the prompt nuclear radiation rate effects on weapon materials and components exposed on the Quince and Fig events. Project 34.8, 34.9, and 34.10 made measurements on the Quince and Fig events sufficient to delineate the gamma radiation fallout and to define a faliout model associated with : a for use with any wind pattern. This permitted evaluation of” their limits. 22 AFWL/HO significant intensities and
