THE SPACE PARTICLE COMPOSITION DETECTOR ABOARD FY-1C SATELLITE AND ANALYSIS OF PARTICLE RADIATION IN SOUTH ATLANTIC ANOMALY
风云一号C星空间粒子成分探测器及SAA区粒子辐射实测分析

The space particle composition detector aboard FY-1C satellite can simultaneously detect proton spectrum, electron integrated flux and heavy ion composition. During the maximum of the 23 rd solar cycle, the high energy particle radiation in the South Atlantic Anomy (SAA) of 860 km altitude had been detected for more than three years by the space particle composition detector. The particle radiation characteristics in the SAA are obtained according to the observed data from space particle composition detector. The effects on particle radiation in the SAA by solar proton events and magnetostorms are analyzed.
