STUDY OF ADVANCED FLIGHT VEHICLE POWER SYSTEMS. VOLUME I - ANALYTICAL STUDY
Abstract
A group of radiation etectors for monitoring solar-flare radiation in the upper atmosp ere was flown on a series of balloon flights to altitudes of about 125,000 ft at Bemidji, Minnesota, during the su mer of 1961. The instrumen s consis ed of a scintill tion telescope o me sure high fluxes of protons between 10 and 70 Mev, two neutron detectors to have different neutron detection efficiencies, and a shielded geiger-count r monitor. Balloons were flown both during a period of solar di turbance and duringA DAY OF NORMAL ACTIVITY. The neutron counting rates observed in both neutron etectors as a function of altitude and time are compared for all flights. In addition, he n utron counting rates observed on a day of normal activity are compared with the neutron fluxes calculated assuming a source of neutrons produced only by pri ary cosmic rays interacting in the atmosphere. The calculated and experimentally observed flu es re in reasonably good agreement. Because of an electronic malfunction, the information obtained from the proton telescope was considered unreliable.
