ONR-307 experiment on the Combined Release and Radiation Effects Satellite (CRRES). Interim technical report, Jul 88-Mar 91

Technical Report ·
OSTI ID:5181622
The Combined Release and Radiation Effects Satellites (CRRES) geosynchronous transfer orbit with an apogee of 35,786 km makes it an ideal platform to study problems related to the radiation belts and its effects on spacecraft systems. The instrumentation on CRRES can be broadly divided into three categories: (1) engineering experiments, (2) radiation belt experiments, and (3) plasma and fields experiments. The ONR-307 payload consists of three different types of instruments that acquire data on the composition of the plasma in the energy range from 0.5 to 1000 keV and on energetic electrons from 20 to 5000 keV and protons from 500 keV to 100 MeV. The data from these instruments provide important information for modeling radiation belt particle populations and understanding the sources and losses of these particles. The ONR-307 instruments were initialized by August 7, 1990 and have been operating flawlessly throughout the CRRES mission. Initial results show that the data quality is excellent. A period of high magnetic activity in late August has been selected for detailed study by the CRRES science team. Data analysis is continuing and future efforts will concentrate on the validation of the data and coordinated measurements with other CRRES instruments.
