Charge-exchange measurements of high-energy fast ions in LHD using negative-ion neutral beam injection
W. H. J. Hayashi, W. W. Heidbrink, C. M. Muscatello +10
A new sightline geometry for the fast-ion D-alpha (FIDA) diagnostic on the Large Helical Device (LHD) has been confirmed to measure signals for high-energy fast ions produced by ne…

Response of negative ion beamlet to RF field in beam extraction region
Kenichi Nagaoka, Haruhisa Nakano, Taiga Hamajima +8
Beam-focusing characteristics of negative ion beams have been experimentally investigated with a superimposition of a controlled perturbation of RF field in a filament-arc discharg…
