Design study of 10 kW direct fission target for RISP project

Abstract

We are developing Isotope Separation On-Line (ISOL) target system, which consists of 1.3 mm-thick uranium-carbide multi-disks and cylindrical tantalum heater, to be installed in new facility for Rare Isotope Science Project in Korea. The intense neutron-rich nuclei are produced via the fission process using the uranium carbide targets with a 70 MeV proton beam. The fission rate was estimated to be ∼1.5 × 1013/sec for 10 kW proton beam. The target system has been designed to be operated at a temperature of ∼2000 °C so as to improve the release effciency.
