摘    要: 兰州重离子加速器冷却储存环HIRFL-CSR,是一个多用途、多功能的双冷却储存环同步加速器系统,由主环CSRm和实验环CSRe构成,并以兰州重离子级联回旋加速器HIRFL作注入器。CSR利用高频变谐波的方法,将重离子束的能量从7~25 MeV/u同步加速到200~1 000 MeV/u,同时利用重离子储存环中空心电子束冷却技术将束流品质提高1个数量级,并通过储存环的快引出及慢引出,提供多种类的重离子束以及放射性次级束(RIBs),以开展范围更广精度更高的物理实验。该装置于2007年投入运行,已取得了重要的运行结果,如实现了剥离注入与多圈注入、空心电子束对重离子束的冷却与累积、变谐波宽能区同步加速、等时性环型谱仪、RIBs的产生收集与ToF高分辨质量测量以及高能重离子束的变能慢引出等。

关 键 词:重离子加速器  冷却储存环  重离子束累积  电子冷却  放射性次级束

Abstract: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 man
Keywords:cooler-storage-ring  beam accumulation  electron-cooling  RIBs
