在本文中，我们提出的特点，沉淀高能离子/电子与波粒子相互作用的等离子体层羽在2005年7月18日的磁暴期间的观测NOAA 15 NOAA 16，IMAGE卫星和芬兰网络的搜索线圈磁强计。NOAA 15卫星和芬兰搜索线圈磁强计网络的共轭观测表明，沉淀离子通量的急剧增强是EMIC波散射到损失锥中的环电流（RC）离子的结果。这些沉淀的RC离子导致了IMAGE FUV观测到的分离的极光下质子弧。此外，通过对NOAA 15和NOAA 16的观测，沉淀电子通量的峰值与沉淀质子通量的峰值在赤道方向，这与Yuan et al.（2012）同伴论文中星团C1观测到的ELF嘶嘶声和EMIC波的区域分离一致。结合姊妹论文的结果，我们证明了等离子体层羽流中的波活动（ELF嘶嘶声，EMIC波）和电离层高度的高能离子/电子沉淀之间的联系。因此，在磁暴期间，高能质子的沉淀与高能电子的沉淀在纬度上分离是等离子体层羽-RC-电离层相互作用的一个重要特征。
In this paper, we present characteristics of precipitating energetic ions/electrons associated with the wave-particle interaction in the plasmaspheric plume during the geomagnetic storm on July 18, 2005 with observations of the NOAA15 NOAA16, IMAGE satellites and Finnish network of search coil magnetometers. Conjugate observations of the NOAA15 satellite and the Finnish network of search coil magnetometers have demonstrated that a sharp enhancement of the precipitating ion flux is a result of ring current (RC) ions scattered into the loss cone by EMIC waves. Those precipitating RC ions lead to a detached subauroral proton arc observed by the IMAGE FUV. In addition, with observations of NOAA15 and NOAA16, the peak of precipitating electron flux was equatorward to that of precipitating proton flux, which is in agreement with the region separation of ELF hiss and EMIC waves observed by the Cluster C1 in the Yuan et al. (2012) companion paper. In combination with the result of the companion paper, we demonstrate the link between the wave activities (ELF hiss, EMIC waves) in plasmaspheric plumes and energetic ion/electron precipitation at ionospheric altitudes. Therefore, it is an important characteristic of the plasmaspheric plumes-RC-ionosphere interaction during a geomagnetic storm that the precipitation of energetic protons is latitudinally separated from that of energetic electrons.
