兰州重离子加速器冷却储存环(HIRFL-CSR)是我国自主设计建造的第一个大规模、高能量、全离子加速的重离子冷却储存环系统,属国家“九五”重大科学工程。它利用原有的兰州重离子回旋加速器系统(HIRFL)作注入器,采取主环CSRm与实验环CSRe耦合的双环结构,可将重离子束的能量从1—100MeV/u的低中能区提高到500—1000MeV/u高能区。同时利用空心电子束冷却技术将束流品质提高一个数量级,并提供包括放射性束RIBs在内的更多种类的重离子束,用以开展范围更广、精度更高的物理实验,是一个开展多学科交叉研究的大科学平台。2000年4月HIRFL-CSR工程由原国家计委批准开工建设,总投资2.935亿元;2005年9月建成并开始试运行;2008年7月30日通过国家验收且正式投入运行。验收意见指出,HIRFL-CSR工程全面优质完成了建设任务,实现了验收指标,其中主环加速碳、氩束流的能量和流强超过了设计指标,总体性能达到了国际先进水平。
Lanzhou Heavy Ion Accelerator Cooling Storage Ring (HIRFL-CSR) is the first large-scale, high-energy, all-ion accelerated heavy ion cooling storage ring system independently designed and built in China. It belongs to a major scientific project of the State “95”. It uses the original Lanzhou heavy ion cyclotron system (HIRFL) as the injector, and adopts the double ring structure of the main ring CSRm and the experimental ring CSRe to increase the energy of the heavy ion beam from low to medium energy region of 1-100 MeV / u To 500-1000MeV / u energy zone. At the same time using hollow electron beam cooling technology to improve beam quality by an order of magnitude, and including radioactive beam RIBs, including more types of heavy ion beams, to carry out a wider range of higher accuracy of the physical experiment is a more Interdisciplinary research of large science platform. April 2000 HIRFL-CSR project was approved by the former State Development Planning Commission to start the construction, with a total investment of 293.5 million yuan; September 2005 completed and started trial operation; July 30, 2008 passed the national acceptance and formally put into operation. Acceptance Opinion pointed out that, HIRFL-CSR project completed the construction of a comprehensive high-quality tasks to achieve the acceptance criteria, including the main ring to accelerate carbon and argon beam energy and flow exceed the design indicators, the overall performance has reached the international advanced level.
