HIRFL-CSR project

HIRFL-CSR, the project that was proposed to upgrade the HIRFL facility, is a multifunctional Cooling Storage Ring (CSR) system, consisting of a main ring (CSRm) and an experimental ring (CSRe). The heavy ion beams from the HIRFL will be injected, accumulated, cooled and accelerated to high energy in the CSRm, then fast-extracted to produce radioactive ion beams (RIB), highly-charged stage ions, or slow-extracted to do experiment. The secondary beams will be accepted by CSRe and used for internal-target experiments of the high sensitive and high precision spectroscopy with cool beam. CSR project was started in end of 1999 and finish in the end of 2004. The period from beginning of 2000 to the summer of 2001 is the time for the building construction, fabrication design, prototype experiments. In this paper, the outline and status of the project will be reported.
