Experimental aspects of ion acceleration and transport in the Earth's magnetosphere. [Plasmasphere (leV), exo-plasmasphere (leV-lkeV), plasma sheet (1-10 keV), ring current (10-300 keV), trapped radiation belts (>300 keV)]

Major particle population within the Earth's magnetosphere have been studied via ion acceleration processes. Experimental advances over the past ten to fifteen years have demonstrated the complexity of the processes. A review is given here for areas where composition experiments have expanded perception on magnetospheric phenomena. 64 refs., 6 figs., 1 tab. (WRF)
