Circulation of energetic ions of terrestrial origin in the magnetosphere

Shelley et al. (1972) have first reported that ions of terrestrial origin might represent a nonnegligible component of the hot magnetospheric plasmas. The present paper is concerned with those observational results which provide keys to the circulation of energetic magnetospheric ions of terrestrial origin, taking into account ions having energies greater than approximately 10-100 eV. It is pointed out that these are the ions which might be expected to circulate through the plasma sheet. On the basis of the observed ion composition of plasma storage regions (the plasma sheet and ring current) and the source and transport regions (auroral zone acceleration region, polar cap, boundary layers and magnetotail lobes), it is concluded that during magnetically active periods the primary circulation of energetic terrestrial ions is directly from the auroral acceleraton region into the plasma sheet boundary layer and central plasma sheet. 44 references.
