Subfile: ERA (Bnergy Research Abstracts); NTS (NTIS). Country of Origin: United States Country of Publication: United States Abstract: This is a report on the instrumentation for Projects 1.2a, 1.3, and 1.7 of Operation CASTLE. This instrumentation was devised to measure pressures, shock winds, and ground accelerations from large scale detonations. Project 1.2a measured pressures less than 75 psi, Project 1.3 recorded shock winds, and Project 1.7 was concerned with close-in ground accelerations. In addition to the formal instrumentation program field tests of several new type gages were made. All new gages had had laboratory tests but field tests were made to insure that the gages would perform under actual operating conditions. Records were taken on 112 information channels. Of these, 99 gave good information, six gave information up to arrival of the shock wave and seven gave no information.; Major Descriptors: *CASTLE PROJECT -- MEASURING INSTRUMENTS Descriptors: ACCELERATION; GROUND MOTION; NUCLEAR EXPLOSIONS; PRESSURE GAGES; SHOCK WAVES; TRANSDUCERS; WAVE PROPAGATION Broader Terms: EXPLOSIONS; MEASURING INSTRUMENTS; MOTION; NUCLEAR EXPLOSIONS Subject Categories: 450200* -- Military Technology, Defense -- Nuclear Explosions & Explosives Author(s): Title: {Item 445 from file: 103) EBRA-07-023044; EDB-82~-050136 Triantafellu, R.

Country of Origin: United States Country of Publication: United States Abstract: The objective of Project 6.1 (CASTLE) was to determine whether the equipment-operating procedures used in obtaining radar scope photos for IBDA (Indirect Bomb Damage Assessment) of previous A-bomb tests were valid for thermonuclear weapons. The procedures for obtaining the radar photos involved positioning of bombers at a safe distance from ground zero at operational altitudes, with radar scanning ground zero during, and immediately after, the weapon burst. The photography obtained on each shot was generally good. The conclusions are that a high yield weapon burst can be readily detected by the bomber’s radar, and that present equipment-operating techniques are adequate. These conclusiong must be qualified.; Major Descriptors: *CASTLE PROJECT; *THERMONUCLEAR EXPLOSIONS *THERMONUCLEAR EXPLOSIONS -- PHOTOGRAPHY Descriptors: DAMAGE; Broader Terms: RADAR EXPLOSIONS; MEASURING INSTRUMENTS; -- DETECTION; NUCLEAR EXPLOSIONS; RANGE 9003931 10/5/745 00875295 Weaponry,
