摘要
This paper presents the observational results of space energetic particles obtained by the Cosmic Ray Composition Monitor (CRCM)onboard the Chinese satellite, Fengyun-1(B). These results, including those of a few solar proton events, the geomagnetically trapped particles and the anomalous cosmic ray components, were obtained from 3 September 1990 to 15 February 1991. The observed elements include H, He, C, N, O and Fe of energies from 4—23 MeV/n. It was found that the proton fluxes of the Inner Radiation Belt (IRB) increased obviously during the period of solar proton event (SPE). A few kinds of heavy ions (Z≥6) were also detected in the IRB. As to the anomalous cosmic ray component (ACRC), in addition to C, N and O, anomalous iron particles were also recorded. Moreover, the effects of space particle radiation on the satellite are analyzed.
