A calculation of the radiation environment for satellite experiments operating below the Van Allen belts

摘要

A Monte Carlo simulation of the cosmic rays interaction with the Earth's atmosphere and magnetosphere has been developed.This simulation has been validated by a thoughtful comparison with the cosmic and undercutoff particle fluxes measured by the AMS experiment in 1998 at an altitude of approx400 km.The results of our simulation are used to calculate the flux of secondary particles in the region above the AMS orbit and below the Van Allen belts (1000 km),where several experiments are scheduled to take data in the next years.
