HIRFL STATUS AND HIRFL-CSR PROJECT IN LANZHOU

HIRFL-CSR, a new accelerator project planned at the Heavy Ion Research Facility in Lanzhou (HIRFL), is a multipurpose Cooling Storage Ring system which consists of a main ring (CSRm) and an experimental ring (CSRe). The two existing cyclotrons SFC (K=69) and SSC (K=450) of the HIRFL will be used as its injector system. The heavy ion beams from the HIRFL will be accumulated, cooled and accelerated in the main ring, and then extracted to produce radioactive ion beams (RIB) or highly charged heavy ions. The secondary beams (RIB or highly charged ions) can then be accepted by the experimental ring for internal-target experiments. In this paper the status of the HIRFL and the details of the HIRFL-CSR project will be reported.
