HIRFL status and HIRFL-CSR proposal

Since the Heavy Ion Research Facility at Lanzhou (HIRFL) was put into operation in 1989, 19 kinds of ion have been extracted for the experiments and a lot of improvements was finished. In order to provide high quality stable and unstable nuclear beams for many experiments, the HIRFL Cooler-Storage Ring Proposal has been submitted to Chinese Academy of Sciences. The HIRFL status and the main performance, lattice as well as the main technical problems of Cooler-Storage Ring (CSR) are described in this paper.
