  China Advanced Rare Ion-beam Facility (CARIF) based on China Advanced Research Reactor (CARR) has been proposed in order exploring the frontier of nuclear physics. A target with 5 g 235U is proposed in the project. The thermal neutron fission of 235U will produce radioactive nuclei and the great thermal load (~50 kW). The target of CARIF needs endure high temperature and thermal energy deposit. A new multi-targets configuration is proposed. It consists of several discrete targets instead of traditional single-target structure used in accelerator driven facility. Because there is more thermal radiation area in this configuration, thermal radiation capacity is enhanced, so the target can withstand higher thermal power. The temperature distribution of multi-targets was simulated with finite element code. The results show that the configuration of multi targets can effectively reduce the target temperature. From the perspective of target temperature distribution, the configuration could endure 50kW thermal deposit. It's possible to use 5 g 235U in CARIF for production of radioactive nuclide.

  Beijing Radioactive Ion-beam Facilities Isotope Separator On-Line (BRISOL), aiming to generate short life radioactive ion beam (RIB) on-line, is being constructed at China Institute of Atomic Energy(CIAE). Up to now, construction of major equipment for BRISOL is completed, including ion source, vacuum system, separator, optical element, and beam diagnostic system, and assembling is underway in laboratory. The on-site installation of all the beam line will be carried out soon. All the major element prototype including surface ion source, quadrupole, hexapole, multipole and beam diagnostic system have been studied off-line on a test-bench for BRISOL. A Li beam was generated and separated . The primary tests show that the ion source and the optical elements work well. The test charge exchange cell (CEC) is under way. BRISOL will be commissioned next year.
