摘要

The present state of understanding the process of tail reconnectionrnand plasma sheet fast flows obtained fromrnCluster measurements is reviewed. Being a constellationrnof four identical spacecraft, Cluster allows discriminationrnof spatial and temporal variations in magnetic field andrnplasma parameters. Thus it is ideal to study the structurernand dynamics of plasma and fields relevant to reconnection,rnwhich is a highly dynamic system. Observations ofrncurrent sheet crossings near the X-line obtained the geometryrnof reconnection region and confirmed the effectsrnof unmagnetized ions including the Hall-current and itsrnclosure currents. Cluster multi-point observations identifiedrnthree dimensional structures and dynamics of thernfast flows in the plasma sheet, which could be ascribed tornthe localized and/or temporal features of the reconnectionrnregion.
