Group Abstract: Clump and hole creations are observed with TAE-bursts in energetic neutral spectra at low-magnetic field
configurations of LHD. Energy slowing-down of the clump and the hole are also observed, experimentally. From the slowing-down time analysis of the
clump or hole, the location of each of the 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 reveals the enhanced radial transport
of energetic particles by TAE-bursts on LHD. Note: In special issue in Nuclear Fusion - volume 46, issue 10
