Book excerpt: This study outlines the achievements of the second year of work on data acquired by the Lockheed Ion Mass Spectrometer (IMS-LO), one of the space radiation group of instruments on the Combined Release and Radiation Effects Satellite (CRRES). The purpose of IMS-LO is to study the low energy (110eV-35 keV) ion component of the current plasma. The primary data processing is almost complete, as is the construction of databases of validated low energy ion data. A preliminary version of a static model of low energy ion composition in the ring current has been constructed. This shows the average equatorial energy and pitch-angle distributions of ion fluxes organized by L and local time. Non- equatorial distributions can be obtained by adiabatic mapping. A number of events from both quiet and disturbed times have been selected for special studies. The quiet time convection electric field was estimated using the Liouville's Theorem method. Several events were studied which suggest that induced electric fields can be important in the acceleration and loss of ions.
