在LHD低磁场结构的高能中性光谱中，用TAE爆发观察到团块和空穴的产生。实验还观察到团块和空穴的能量减慢。通过对团块和/或空穴的慢化时间分析，确定了每个轨道的位置。每个轨道的漂移面在TAE爆发的间隙位置附近都有一个最大值或第二个最大值。在高能光谱中同时观测到团块和空穴的形成，揭示了高能粒子在LHD上的TAE爆发增强了径向输运。
Clump and hole creations are observed with TAE bursts in energetic neutral spectra at low-magnetic field configurations of the LHD. Energy slowing down of the clump and the hole are also observed, experimentally. From the slowing down time analysis of the clump and/or hole, the location of each orbit is identified. The drift surface of each orbit has its maximum or second maximum close to the gap location of the TAE burst. The simultaneous observations of clump and hole creations in the energetic spectra reveal the enhanced radial transport of energetic particles by TAE bursts on the LHD.
