Medium-energy particle experiments–ion mass analyzer (MEP-i) onboard ERG (Arase)

Abstract The medium-energy particle experiments–ion mass analyzer (MEP-i) was developed for the exploration of energization and radiation in geospace (ERG) mission (Arase), in order to measure the three-dimensional distribution functions of the inner-magnetospheric ions in the medium energy range be...
