Abstract :
This paper presents particle flux measurements and single event effect (SEE) data obtained with Influence of Space Radiation on Advanced Components (ICARE) on the SAC-C orbit (707 km, 98.2°) for the period November 2000-June 2002. An increase of 10 MeV proton flux in the belts is clearly observed and correlated to solar proton events associated with magnetic storms. SEU rate measurements are presented for SRAM and DRAM devices, and their response to solar events shows SEU rate increases (up to a factor of 115) correlated with high-energy protons (E≥84 MeV).
