英文摘要	Understanding the polar cusps is essential for a thorough understanding of the entire physics of the magnetosphere, and of the dynamical interaction between the solar wind and any planetary magnetosphere. Energetic electrons are unique to fully assess magnetic field-line topology and thus should be able to clearly delineate regions of open and closed magnetic field lines in the high latitude regions and contributed crucially to understanding and resolving an internal debate going on between groups measuring only the lower energy (< 20 keV) plasma. Energetic electrons with high and stable flux were observed in the high latitude boundary/cusp region when the IMF had a predominate positive Bz component. With measurements at larger separations and more coordination of multiple satellite measurements for particular cusp crossings will it become more evident what the true nature of the cusp is and what roles the cusps play. The boundary normal, velocity and timing analysis obtained by all four spacecraft indicates that the multiple cusp phenomena is most likely caused by the oscillation of the single northern cusp which was shifted back and forth. Cusp oscillating with a period of 22 min are observed by Cluster satellite in the high latitude region, in the meantime, the cold-dense plasma with fluctuations (20 min period) are observed in the dusk-side of the tail plasma sheet by Geotail satellite. This is consistent with the idea that the high latitude reconnection during northward IMF is the responsible mechanism of the formation of the cold-dense plasma sheet.; EI; 0
