Abstract
The investigation of the mass and charge composition of the energetic (keV) plasmas in the earth’s magnetosphere represents one of the most important approaches to establishing the origin of the particles in the plasmas and to understanding the complex electro-dynamic processes occurring within or at the boundaries of the magnetosphere. The processes responsible for the injection, energization, transport, and loss of the plasma components are still largely unidentified and some of the processes are likely to be dependent on the mass and/or charge of the components. Thus, measurements of the differences in energy spectra, spatial distributions, and temporal behavior of the various ionic components may provide the key to identifying and characterizing the important processes. In this paper we shall limit our discussion of the composition of the energetic particles in the magnetosphere primarily to particle energies less than 50 keV. The composition measurements at higher energies and their importance in understanding the magnetospheric processes have recently been reviewed by West (1975) and Krimigis (1973).
