HIRFL Today Original Research Article

HIRFL was upgraded from beginning 2000. Besides of researches on nuclear physics, atomic physics, irradiative material and biology, the cancer therapy by heavy ion and hadron physics are being developing. The injector system of SFC+SSC can provide all ions from proton to uranium with higher intensity. The Cooling Storage Ring (CSR) has accelerated beams successful. The ions 12C6+, 36Ar18+, 129Xe27+ have been accelerated up 1000MeV/u, 235MeV/u with about 109∼108 ions per spill respectively. The beam momentum dispersion was measured from 4×10−3 to 2×10−4 after cooling by the electron cooler or ∼4×10−4 after accelerated to 1000MeV/u without cooling. In order to improve the nuclear structure and heavy isotope research in SFC+SSC energy domain. A Wien filter was added in front of RIBLL and gas was filled in first section of RIBLL; a new spectrometry SHANS has being installed. Presently, there are two starting version experimental setups at CSR.
