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 (T1/2=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.
