CRIB, the low-energy RI beam separator

CRIB is an radio-isotope (RI) beam separator, developed as one of the main apparatuses of CNS. It can produce RI beams at low energies, just corresponding to the temperature of explosive stellar objects and the excitation energy of atomic nuclei. At CRIB, intense and pure RI beams can be produced with a high efficiency, by the conversion of high-current metallic-ion beams, provided by the Hyper-ECR ion source of CNS, into RI beams with a cryogenic dense taget, as well as the purification with magnets and Wien-filter system. The nuclear astrophysics group of CNS is actively carrying out researches, forming international collaborations.
