在LHD中，仅用中性束就成功地建立了等离子体。1.6MW中性束注入10 ~（-3）Pa的低密度中性气体靶约0.3s后，产生了1018 m ~（-3）的完全电离等离子体。在保持束流开启的情况下，额外的气体抽吸可以充分增加等离子体密度以吸收束流，并且之后维持了5 × 1019 m-3的致密等离子体。该技术专用于具有真空限制磁场结构的螺旋系统，并且不需要其他辅助加热工具，例如ECH，其已用于用NBI产生靶等离子体。
Plasma was successfully built up by neutral beams alone in LHD. After injecting 1.6 MW neutral beams through a low density neutral gas target of 10-3Pa for about 0.3 s, fully ionized plasma of 1018 m-3 was generated. Keeping the beams on, additional gas puff could increase the plasma density sufficiently for absorption of the beam, and a dense plasma of 5 × 1019 m-3 was sustained afterwards. This technique is specific to a helical system that has a vacuum confining magnetic field structure, and no other assisting heating tools are required such as ECH, which has been used for producing target plasma with NBI.
