GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The Naval Research Laboratory undertook the performance of certain experiments as part of the 1948 atomic weapon tests, on different islands of Eniwetok Atoll, were involved. This volume (Volume 2) is a presentation of the overall electronics problem, a discussion of the general design and construction of the electronic components, a detailed description and functional analysis of the operational and test electronic components, and a description of the overall test installations at each site with a description of the test methods and procedures were followed.

Annex 1.9. Air drop instrumentation. Part 3. Disc camera Corporate Source: Edgerton, Germeshausen and Grier, Inc., Boston, MA (USA) Publication Date: 1 Sep 1985 p 39 Report Number(s): AD-A-995302/7/XAB Document Type: Report Language: English Journal Announcement: EDB8611 Availability: NTIS, PC A03/MF AOl. Subfile: ERA (Bnergy Research Abstracts). GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The disc camera was designed for use to determine the growth characteristic of the fireball and so the yield. The instrument has three separate optical systems and can record three separate streak images of the fireball on a rotating glass photographic plate. The angular velocity of the photoplate at the time of exposure is determined by marker pips recorded on the photoplate. The marker generator is gated by a phototube and is turned off by a time delay. Time to minimum can be determined directly from the streaks and by the use of the,scaling laws. Bhangmeter yield can also be determined. For Operation Greenhouse, two cameras were operated in phototowers. Good records were obtained on the first two shots. On the George Shot, which was a daylight test, the photocell in the fiducial marker did not function and no records were attained. The cameras were not operated on 9003897
