Subfile: Country of Origin: United States Country of Publication: United States Abstract: The primary purpose of the spatial measurements was to gain data from which the distribution of fission fragments as a function of time could be computed. Since it was considered that the previous Sandstone tests did not include enough sample points in space to provide more than a very rough idea of the distribution of fission fragments with time, it was decided, to provide more collimators, detectors with a faster response, a recorder with better time resolution, and more protection for the detectors. The radial motion of the fission fragments was expected to be available directly from the measured times of arrival of the source at the field of view of each detector.

Subfile: ERA (Energy Research Abstracts). GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: Section LAJ-16 was made a part of Task Group 7.1 for the purpose of initiating and maintaining an accurate file of maps and wiring diagrams, showing the positions of all Los Alamos and Service experimental installations at the Eniwetok Proving Grounds. Proper location of all underground cables between stations occupied a prominent place in the initial planning. In order to effectively coordinate the cable installations with the main construction program, this section assumed the responsibility of acting as liaison among other LAJ sections and the Service Units designated to perform the work. Later this liaison function was expanded until LAJ-16 eventually became an active participant, rather than a coordinator, in cable laying, wiring, and generator maintenance.
