Etude de la cinétique des particules dans les couches frontières de la magnétosphère terrestre à l'aide des observations des satellites CLUSTER et DOUBLE STAR

摘要

The near-Earth space environment is complex and diverse. Particle kinetics plays a key role in understanding the nature of key phenomena and physical processes taking place in the Geospace. By means of the high-resolution data recorded by the multiple-point Cluster and Double star spacecraft, the present thesis investigated low energy ion kinetics in some crucial boundary layers of the terrestrial magnetosphere. The dominating roles played by the particle kinetics in the formations of those small-scale plasma structures and the feature of cross-scale coupling processes are summarized.
