日本JT - 60的基于负离子的中性束注入器（N - NBI）是为在更高密度等离子体中进行等离子体芯部加热和中性束电流驱动而研发的。N - NBI系统于1996年建成，建成后不久便开始努力提高束流功率和束流能量。N - NBI系统已经能够产生能量为380keV、电流为14.3A的氘负离子束以及能量为360keV、电流为18.5A的氢负离子束。在JT - 60上进行的N - NBI实验期间，已稳定地注入了能量为350keV、功率为5.2MW的氘中性束，持续时间达0.7秒，并且JT - 60等离子体对N - NBI高能束注入的响应已被证实与理论预测相符。
The negative-ion based neutral beam injector (N-NBI) for JT-60 has been developed for plasma core heating and neutral beam current drive in higher density plasmas. Construction of the N-NBI system was completed in 1996, and just after this completion, the efforts to increase beam power and beam energy started. The N-NBI system has already operated with negative ion beams with 14.3 A at 380 keV of deuterium and with 18.5 A at 360 keV of hydrogen. During N-NBI experiments on JT-60, a deuterium neutral beam power of 5.2 MW at 350 keV has been injected for 0.7 s stably, and the response of the JT-60 plasma to high energy beam injection with the N-NBI has been confirmed to be in agreement with a theoretical prediction.
