HIRFL-CSR是兰州新建的重离子冷却储存环同步加速器系统。它由一个多用途、多功能的主环（CSRm）和一个实验环（CSRe）组成。兰州重离子加速器（HIRFL）现有的两台回旋加速器SFC（K = 69）和SSC（K = 450）作为注入系统。HIRFL产生的能量为7~25 MeV/u的重离子束首先注入CSRm，伴随着积累、e冷却和加速，最后以500~1 000 MeV/u的能量缓慢引出，用于许多外靶实验。或以200~700 MeV/u的能量快速引出，在束线的主靶上产生放射性离子束或高Z束。次级束流将被接收并储存在CSRe中，用于许多内靶实验。从2006年到2008年，HIRFL-CSR完成了所有调试活动，包括剥离注入，多匝注入，空心电子束冷却积累，不同RF谐波的宽能量范围内的斜坡，CSRe的等容模式调试，CSRe中RIBs的质量测量和CSRm的缓慢提取。
HIRFL-CSR is a new heavy ion cooler-storage-ring synchrotron system in Lanzhou. It consists of a main ring (CSRm) and an experimental ring (CSRe) with multi-usages and multi-functions. The two existing cyclotrons SFC (K = 69) and SSC (K = 450) of the Heavy Ion Research Facility in Lanzhou (HIRFL) are used as its injector system. The heavy ion beams from HIRFL with the energy of 7~25 MeV/u will be first injected into CSRm, accompanying with the accumulation, e-cooling and acceleration, and finally extracted slowly with the energy of 500~1 000 MeV/u for many external-target experiments, or extracted fast with the energy of 200~700 MeV/u to produce radioactive ion beams (RIBs) or high Z beams at the primary target of the beam line. The secondary beams will be accepted and stored in CSRe for many internal-target experiments. From 2006 to 2008 all the commissioning activities of HIRFL-CSR were made, including stripping injection, multi-turn injection, cooling accumulation with hollow electron beams, ramping in a wide range of energy with different RF harmonics, isochronous mode commissioning of CSRe, mass measurement of RIBs in CSRe with ToF and slow extraction from CSRm.
