AE8/AP8 Implementations in AE9/AP9, IRBEM, and SPENVIS

Abstract

This report describes validation results for the AE8/AP8 legacy models as implemented in the AE9/AP9/SPM architecture in comparison to AE8/AP8 as implemented in the SPENVIS and IRBEM tools. The CmdlineAe9Ap9, SPENVIS and IRBEM implementations of the AE8/AP8 and SHIELDOSE2 models were used with a GTO satellite ephemeris for 10 full orbits, for the calculation of electron and proton integral and differential flux values, and their associated dose values for the three defined geometries. The flux values and dose results from these three implementations closely match with the recent revisions of the CmdlineAe9Ap9 (included in V1.05) and IRBEM library. Some small differences are observed, but can be attributed to differences in the magnetic field models and AE8/AP8 model settings, and for dose results to differences in the SHIELDOSE2 processing settings.
