tistle rockots sith variatl-ag in setght and tog for vittt.tde cr Six sttifors were located at rol, 10,000, 59,°90, 50,000, and £3,009 .t vitl- tude directly beneath the burst, and at 30,000 ft from the burst along the bomb axis and perpendicular to It. Each carrier had a 226 to 235 Mc band telemetering system aboard with from four to efght subcarriers. The FM-FM receiving and recording station wag located near the launch aite on Johnston Island. All six carriers contalned transducers for measuring neutron and gamma ray fluxes. The neutron transducer consisted of activation fofls that were counted by a scintillometer circult during the fall time of the nose, Gamma rays were.measured as dose rate by scintillometers and as total dose by silver-activated phosphorglass and a densitometer. In addition, the two stations 30,000 ft from the burst measured x-ray and total thermal inputs at their locations. Both transducers utilized ballistic calorimeters containing resistance wires connected in a four-arm bridge, The total thermal was absorbed by a polished aluminum cone mounted Inside a truncated cone. The x rays were filtered through beryllium discs of 50 . and 70 mil thickness. The remaining energy impinged upon the calorimeter. These six carriers also contained film packs for measuring high gamma flux and material samples for effects evaluation. The noses were designed for parachute retardation and for recovery from the ocean, 2. The Redstone carried two 4 KMc diagnostic systems for measuring | HE transit time MIN a5 system and the: J WH fuzing system was monitored by 226 Mc telemetry equipment. All six instrument carriers and the Redstone were tracked by two MIDOT (radio interferometer positioning system) stations for relative posi-— tioning of transducers and the burst. The transmitters aboard each carrier served as the beacon. 3. Two radiochemical sampling noses were to be carried through the Teak debris by two stages of the modified-LaCrosse motors, These sampled, sealed, and lowered to the water a collection of the burst residue for labératory analysis, 4. <A system for measuring wind velocity at 250,000 ft altitude was designed to permit adjustment of the radchem sampler trajectories to increase the likelihood of sending the sampler through the densest debris. This measurement was made by carrying 5 cm chaff to altitude on a Deacon-Arrow I rocket, ejecting the chaff, and tracking it with a MSQ Radar. ~ S. The RF attenuation measurements were made by carrying eight transmitters (four operating near 225 Mc and four near 1500 Mc) aloft on eight two-stage rockets and recording received si rate locations. Six of these carriers were and two were 6. Optical instrumentation included high speed and longer time pho-~ 7. The warheads used on the high altitude shots were modified, in- tography through three different narrow band filters, a high resolution spectral record, plate cameras located at each MIDOT station for location of burst position, and black and white and color documentary photography. stalled, checked out, and armed by Program 32. All equipment used on Teak operated as designed with the following ex- ceptions: 1. The two radchem samplers appeared to suffer structural damage at the time of second-stage burning, became unstable, and fell back to the 51 AbWiusne
