Heavy Ions Research Facility in Lanzhou(HIRFL)

Heavy ions accelerator has greatly scientific significance in nuclearphysics, atomic physics and astrophysics. It is also of great socialneeds in many application fields, such as nuclear detection, radiationmedicine and medical physics. In addition, Heavy ions acceleratorhas important application prospects in the interdisciplinary fieldsof nuclear physics, nuclear technology, radiation biology, materialscience, biology and agriculture. Therefore, heavy ions acceleratormakes great contributions to the promotion of human development andsocial progress. At present, there are more than 30 large scale heavyions accelerators. And the main overseas heavy ions accelerators arethe BNL-RHIC in the United States, the RIKEN-RIBF in Japan,the MSU-FRIB in the United States, the GANIL-SPIRAL2 in France and the FAIR in Europe which is under construction.In China, however, there are the BRIF in Beijing and the HIRFL inLanzhou being operation and High Intensity heavy-ion Accelerator Facility(HIAF) which will be built in Huizhou. Heavy Ions Research Facilityin Lanzhou (HIRFL), one of the most important research facilitiesfor nuclear physics in the world, is the largest scale heavy-ion acceleratorfacility with the most ion species and the highest ion energy in Chinaat present. And its main parameters have reached international advancedlevel. HIRFL is composed of ECR ion source, sector focused cyclotron(SFC), separated sector cyclotron (SSC), radioactive ion beam linesRIBLL1 and RIBLL2, cooler storage rings CSRm and CSRe, and many terminals.HIRFL can accelerate all ion species and provide high quality stablebeams and radioactive beams with many ion species and broad energyranges to carry on the heavy-ion physics and crossing discipline research.This paper is mainly to present the status of HIRFL and its progress,and the development of heavy-ion accelerator facilities at home andabroad are also introduces briefly.
