离子源注入型IH加速器有望发展成为一种紧凑型低功耗离子加速器，为有效验证该加速结构的束流俘获效率，中国工程物理研究院流体物理研究所设计了一套将质子束从0.04 MeV加速到2.0 MeV的IH加速腔。目前已经完成了该腔的腔体加工，开展了高频参数冷测及腔体调谐研究。通过漂移管调谐和电感调谐，减小了腔体的频率误差和加速电压分布误差。模拟计算实测电场下腔体的束流俘获效率，由调谐前的16%提高到调谐后的34%。冷测调谐结果表明，该加速腔的各项参数达到设计值，具备进行功率测试和束流测试的条件。

The ultra-high intensity heavy-ion beam is highly pursued for heavy-ion researches and applications. However, it is limited by heavy-ion production of ion source and space-charge-effect in the low energy region. The Heavy-ion Inertial Fusion (HIF) facilities were proposed in 1970s. The HIF injectors have large cavity number and long total length, e.g., there are 27 injectors in HIDIF and HIBLIC is 30 km in length, and the corresponding HIF facilities are too large and too expensive to be constructed. Recently, ion acceleration technologies have been developing rapidly, especially in the low energy region, where the acceleration of high intensity heavy-ions is realized. Meanwhile, superconducting (SC) acceleration matures and increases the acceleration gradient in medium and high energy regions. The length of HIF injectors can be shortened to a buildable length of 2.5 km. This paper will present a review of a renewed HIF injector, which adopts multi-beam linacbased cavities.
