Notes:
During the recent Combined Release and Radiation Effects Satellite (CRRES) mission, a series of chemical releases occurred in the magnetosphere and ionosphere to study a wide range of plasma processes. The experiments were designed to investigate (1) stimulated electron and ion precipitation, (2) ion transport in the magnetotail, (3) critical ionization velocity (CIV), (4) field line tracing and parallel acceleration, (5) diamagnetic cavity formation and collapse, and (6) plasma instabilities. The satellite orbit was highly elliptical having an apogee of 33 600 km and a perigee of 350 km. The range of altitudes permitted variations in background magnetic field strength and injection velocity. The release materials included barium, lithium, strontium, calcium, and europium. In situ diagnostics on board CRRES and ground-based optical instruments recorded the effects of the chemical releases. The CRRES experiments either (1) verified theoretical predictions, (2) showed new, unanticipated effects, or (3) presented none of the predicted phenomena. Examples of each category are illustrated by one of more of the CRRES chemical releases.
