Electron Flux Formations at Middle Latitudes in the Surface Dose of Spacecraft

摘要

In this work experimental data on electron fluxes with energies of 30-500 keV obtained from the ACTIVE satellite experiment (INTERCOSMOS-24 in 1989-1990, altitude from 500 km up to 2500 km) and ones with energies 0.3-1.0 MeV obtained onboard the MIR station (SPRUT-VI experiment in 1999, altitude from 350 km up to 400 km) are presented. The distribution of electron fluxes at low and middle latitudes and the influence of charged particles on surface layers of materials and film coverings are investigated. The comparison with results of other satellite experiments reveals the time and spatial stability of electron flux enhancements at L = 1.2-1.8.
