Reconnection site and ion scale turbulence generation
Résumé
<p><span>We analyze in detail a reconnection site observed by the Magnetospheric Multiscale (MMS) mission in the magnetotail.</span><span> The interval around the X-line is identified based on the ion jet reversal, Hall electric fields and other reconnection signatures. At the reconnection site strong electric fields with amplitudes above 100mV/m are observed. In addition, the region shows strong turbulent variations on ion scales, including magnetic island-like structures. We discuss the cause of strong electric fields, their relation to ion scale structures and associated particle acceleration in this region. </span><span>Of particular interest is the relation of the reconnection site to the generation of kinetic Alfven waves.</span></p>
