Tokai Radioactive Ion Accelerator Complex (TRIAC) is an ISOL-based radioactive nuclear beam (RNB) facility, connected to the ISOL in the tandem accelerator at Tokai site of Japan Atomic Energy Agency (JAEA). At JAEA-tandem accelerator facility, we can produce radioactive nuclei by means of proton induced uranium fission, heavy ion fusion or transfer reaction. Since TRIAC was opened for use in 2005, we have provided RNBs of fission products and ⁸Li. For the production of ⁸Li, we chose ¹³C (⁷Li, ⁸Li) neutron transfer reaction by ⁷Li primary beam and a 99% enriched ¹³C sintered disk target. The release time of Li ions from the ¹³C sintered target was measured to be 3.2 s. We are developing the RNB of ⁹Li (T_1/2=178 ms) but the long release time caused a significant loss of the beam intensity. A boron nitride target which has fast release of Li is developed for ⁹Li beam with intensity of 10⁴ ions/s after separation by JAEA-ISOL.
