中国科学院近代物理研究所承担的强流重离子加速器装置目前已进入了初步设计阶段。增强器作为该装置的主加速器, 可利用双向涂抹技术将238U35+束的粒子数累积至1.0×1011, 并将其从注入能量为17 MeV/u加速至高能量, 引出能量的范围为200-835 MeV/u。为了提供s量级的准连续束以开展辐照实验, 增强器中设计了慢引出系统, 该系统将采用三分之一共振与RF-knockout的引出方法。同步加速器中有两种不同种类的六极磁铁, 用于实现色品校正与共振驱动, 并在设计中考虑了两者能同时运行并互不影响。针对增强器中不同引出能量的238U35+束, 对其相应的稳定接受度模拟结果进行了比较, 并给出了在引出静电偏转板处的光学匹配参数, 这将为增强器中重离子束的慢引出及放射性次级束流分离器的入口光学设计提供重要的理论依据。

The research activities on warm dense matter driven by intense heavy ion beams at the new project High Intensity heavy-ion Accelerator Facility (HIAF) are presented. The ion beam parameters and the simulated accessible state of matter at HIAF are introduced, respectively. The progresses of the developed diagnostics for warm dense matter research including high energy electron radiography, multiple-channel pyrometer, in-situ energy loss and charge state of ion detector are briefly introduced.

Recent research activities relevant to high energy density physics (HEDP) driven by the heavy ion beam at the Institute of Modern Physics, Chinese Academy of Sciences are presented. Radiography of static objects with the fast extracted high energy carbon ion beam from the Cooling Storage Ring is discussed. Investigation of the low energy heavy ion beam and plasma interaction is reported. With HEDP research as one of the main goals, the project HIAF (High Intensity heavy-ion Accelerator Facility), proposed by the Institute of Modern Physics as the 12th five-year-plan of China, is introduced.
