CRRES high energy proton flux maps

The authors present proton flux maps of near-Earth space using the Proton Telescope (PROTEL) detector on CRRES (Combined Release and Radiation Effects Satellite). The proton energy range covered is 1-100 MeV. Contamination of PROTEL measurements due to >100-MeV protons is corrected using loss con...

Description
Summary:The authors present proton flux maps of near-Earth space using the Proton Telescope (PROTEL) detector on CRRES (Combined Release and Radiation Effects Satellite). The proton energy range covered is 1-100 MeV. Contamination of PROTEL measurements due to >100-MeV protons is corrected using loss cone data, resulting in consistency with dosimeter measurements and a Monte Carlo computer model of PROTEL. Two states of the inner magnetosphere were found during the CRRES mission, a quite state having a single proton belt and an active state with a double proton belt. The properties of the new population in the second belt are presented. Comparisons with NASA proton codes are made.< >
