2-DECADE EXPERIENCE OF APPLICATION OF PLASTIC NUCLEAR TRACK DETECTORS TO COSMIC-RAY RESEARCH ON SATELLITES AND ORBITAL SPACE STATIONS

The work generalizes the results obtained during the last two decades in our spaceborne experiments aimed at studying galactic cosmic rays and cosmic ray anomalous component and carried out using solid-state nuclear track detectors (SSNTD) mounted mostly outside spacecraft. The experimental equipment and the techniques for identifying cosmic ray ions and for calculating particle flux values are described. The experimental data are used to construct a modified model for the fluxes and spectra of cosmic ray protons and heavy nuclei to be calculated to within a higher accuracy compared with the earlier models.
