兰州冷却环总体设计

General Design of the CSR Project in IMP

兰州重离子冷却环CSR是兰州重离子加速器研究装置HRRFL的一项升级工程,是一个双冷却储存环系统,由主环CSRm和实验环CSRe构成．从HIRFL回旋加速器系统来的重离子束,首先注入到主环CSRm中进行累积冷却,然后加速到较高的能量引出打初级靶产生放射线次级束RIBs或高离化重离子束,这些次级束再被送到验环CSRe储存起来以开展内靶实验．

CSR, a new accelerator project under the construction to upgrade the existing heavy ion cyclotron system in Lanzhou, is a double cooling-storage-ring system. It consists of a main ring and an experimental ring. The heavy ion beamns from the cyclotron system will be accumulated and accelerated first in the main ring, then extracted to produce radioactive ion beams or high-Z beams, and finally to be send to the second ring for internal-target experiments.
