CSR is a new ion cooler-storage-ring system in IMP, Lanzhou, China, which consists of a main ring (CSRm) and an experimental ring (CSRe) with two previous cyclotrons SFC (K=69) and SSC (K=450) as the injectors. The main construction of CSR was completed in 2005. It was being commissioned in the following two years. In 2008 the main purposes of CSR was focused on the primary ⁷⁸Kr beam with kinetic energy up to 500MeV/u for precise mass spectroscopy at CSRe at isochronous mode. The cancer therapy phase-II in IMP with 10⁰- 250MeV/u carbon beam from CSRm was tested and 6 patients with tumors in the heads were treated successfully.
