The ITER baseline foresees 2 Heating Neutral Beams (HNB's) based on 1 MeV 40 A D(-) negative ion accelerators, each capable of delivering 16.7 MW of deuterium atoms to the DT plasma, with an optional 3rd HNB injector foreseen as a possible upgrade. In addition, a dedicated diagnostic neutral beam will be injecting ≈22 A of H(0) at 100 keV as the probe beam for charge exchange recombination spectroscopy. The integration of the injectors into the ITER plant is nearly finished necessitating only refinements. A large number of components have passed the final design stage, manufacturing has started, and the essential test beds-for the prototype route chosen-will soon be ready to start.
国际热核聚变实验堆（ITER）基线方案预计采用两台基于1兆电子伏特、40安培D(-)负离子加速器的加热中性束（HNB），每台能够向氘氚（DT）等离子体输送16.7兆瓦的氘原子，还预计有一台可选的第三台HNB注入器作为可能的升级选项。此外，一台专用诊断中性束将以100千电子伏特注入约22安培的H(0)，作为电荷交换复合光谱学的探测束。注入器与ITER装置的集成工作已接近尾声，只需进行优化。大量部件已通过最终设计阶段，制造工作已经开始，并且——对于所选的原型路线而言——关键试验台很快将准备好投入使用。
