Calculation Method of Maximum Radiation Conditions and Reliability using Quasi-Dynamic Radiation Belt Model

摘要

We have developed a new dynamic model for the flux of energetic particles trapped in the Earth's radiation belts based on data from the MDS-1 spacecraft. This model covers the energy ranges of 0.4-2 MeV for electrons, 0.9-210 MeV for protons, and 6-140 MeV for helium ions, and it is valid from low altitudes (approximately 500 km) to geosynchronous orbit altitude. This model also includes a magnetic activity variation, solar wind speed variation and pitch angle distributions.We discuss the problems with NASA's radiation model, the developed of the new model, and comparisons between MDS-1 data and new models.
