Scientific paper

Ion cyclotron wave (ICW) propagation along geomagnetic field lines was studied with GEOS 2 (at the equator) GEOS 1 (at geomagnetic latitude = 20 deg) and a ground based station (at the magnetic footprint of GEOS). The catalyzing role of thermal He+ ions in ICW generation was investigated. Results suggest that mirror He+ ions play a role in destabilizing ICW's. These observations together with a ray tracing show that given a sufficient amount of thermal He+, ICW's bounce between He+ induced mirrors; thus ICW's undergo, in an He+ rich plasma, a feedback amplification. Then an unstable medium, the equatorial region, is inserted between two mirrors which are due to the presence in the magnetospheric plasma of thermal He+ ions. This situation is similar to that of masers.
