抽象的。我们提出了一个调查的磁通量绳观察到的四个集群航天器在地球的磁尾磁重联期间。利用博格等人（2012）在2001-2006年期间确定的21个与重联过程相遇的星团列表，我们给出了通量绳的分布和特征。我们发现27磁通绳嵌入在21重联遇到只有11重联流出。与没有磁绳观测相关的重连过程与观测到磁绳的重连过程没有区别。27个通量绳中只有7个显示出高于50 keV的增强的高能电子通量的证据，并且在热粒子测量中没有明显的通量绳特征。我们没有发现明显的相关性之间的磁通绳核心领域和流行的IMF的方向。
Abstract. We present an investigation of magnetic flux ropes observed by the four Cluster spacecraft during periods of magnetic reconnection in the Earth's magnetotail. Using a list of 21 Cluster encounters with the reconnection process in the period 2001–2006 identified in Borg et al. (2012), we present the distribution and characteristics of the flux ropes. We find 27 flux ropes embedded in the reconnection outflows of only 11 of the 21 reconnection encounters. Reconnection processes associated with no flux rope observations were not distinguishable from those where flux ropes were observed. Only 7 of the 27 flux ropes show evidence of enhanced energetic electron flux above 50 keV, and there was no clear signature of the flux rope in the thermal particle measurements. We found no clear correlation between the flux rope core field and the prevailing IMF By direction.
