北京放射性离子束装置(Beijing Radioactive Ion-beam Facility: BRIF) 是国家投资数亿元的大科学工程，将于2014年竣工，填补我国在ISOL型放射性离子束装置方面的空白。其在线同位素分离器（Isotope Separator On Line: ISOL) 能够提供30-300 keV的在线分离束，最高质量分辨率可达20000。此在线同位素分离束可用于开展衰变谱学、放射性离子束注入以及材料表面物理等基础及应用科学研究。. 本项目计划建造一个普适性的衰变谱学平台以满足上述基础及应用科学研究的需求。包括建造束流传输管道及靶室和带传输系统，研制4pi beta探测器、LaBr3 和 BaF2 快定时伽玛探测器等，并配备相应的电子学和数据获取系统。平台建成后将对国内外用户开放，并可和北京大学现有的中子球等耦合，争取在衰变谱学及奇异核结构研究领域发挥重要的作用。

The Beijing Radioactive Ion-beam Facility (BRIF) is a national large-scale scientific infrastrucure of several hundreds of million budget. The facility will be commissioned in 2014, as the national first RIB facility based on the ISOL technique. The Isotope Separator On Line (ISOL) of the facility could deliver mass-separated radioactive beams of 30 to 300 keV with the top mass resolution of 20000. This low-energy ISOL beam can be used for the beta decay study, radioactive ion implatation, and the R&D of ISOL target-ion source, etc. . In this project, a general-purpose decay station will be built to fullfil the above-mentioned needs, which includes the construction of the pipeline, a target chamber and a moving-tape system, as well as the development of a 4pi beta detector, LaBr3 and BaF2 fast-timing gamma detectors, electronics and data acquisition system etc. The station will be open to domestic and international users, and will be compatible with the neutron ball of Peking university, to play an important role in the decay spectroscopic study of exotic isotopes.
