Radioactive nuclei were produced by a thick target with 3-microA and 36 MeV proton beams provided by JAEA tandem accelerator. They were ionized and mass-separated as a singly charged ions by Isotope Separator on-Line (ISOL) of JAEA. Then they are charge-bred to multi-charged ions by using a charge breeding ECR ion source which were developed by KEK. This ECR ion source can also provide the high-intensity stable ion beams.
The multi-charged ions whose mass to charge ratio was 7 were accelerated by using the two linacs called SCRFQ and IH-linacs upto 1.1 MeV/nucleon.
TRIAC was open for users from FY2005 to FY2011. However, since the upgrade of the beam energy which were originally scheduled was found to be difficult due to the budget, we decided to shutdown the facility. The charge breeding ion source and the linacs were given to KAERI, south Korea.
