The original intent of Program 32 was to measure the neutron, X-ray, total thermal, and gamma-ray emission fror —megaton range nuclear device burst at an altitude of 250,990 feet, Additional measurements were incorporated in the prez.:.. a€s techniques became available for attempting them. These were a sampling of the radioactive debris, optical coverage of tne ° burst, and a measurement of RF attenuation and refraction ctvuser by the ionization of the atmosphere. The techniques designed to accomplish the mission of the Program and the specific measurements involved are as follows: l. Stations for measuring the neutron, gamma-ray, X-ray, and total thermal emissions were put at specified locationr by one and two stage rocket propelled instrument carriers. The propulsion units were modified LaCrosse, solid propellant, motors. The auxiliary hardware was designed specifically for these tests. The carriers were unguided, rail launched ballistic rockets with variations of weight and drag for altitude control. The stations were located at 40,000, 50,000,60,000, and 80,000 feet altitude directly beneath the burst and at 30,000 feet from the burst along the bomb axis and perpendicular to it. ' Each carrier had a 226-235 mc. band telemetering system aboard with from four to eight subcarriers. The FM-FM receiving and recording station was located near the launch site on Johnston Island. All six carriers contained transducers for measuring neutr vi and gamma-ray fluxes. The neutron transducer consisted of activation folls that were counted by a scintillometer circuit 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. Ld ari"E050 “ke ~~ PAGE SS
