	The cyclotron facility at National Institute of Radiological Science (NIRS) includes two cyclotrons, a NIRS-930 cyclotron (Thomson-CSF, Kb=110 MeV and Kf=90 MeV) and a small cyclotron HM-18 (Sumitomo-Heavy-Industry). The NIRS-930 cyclotron has been used for radionuclide production, nuclear physics, detector development and so on, since the first beam in 1973. The HM-18 has been used for radionuclide production for PET since the 1994. In recent years, the radionuclide production for Targeted Radionuclide Therapy (TRT) by using NIRS-930 has been one of the most important activities in NIRS. Since demand of radionuclide users on beam intensity is growing, we have launched to upgrade the cyclotron facility, such as installation of multi-harmonic beam buncher in NIRS-930 and a reinforcement of nuclear ventilation system in a cave. Progress on the upgrade for TRT at the cyclotron facility and status of the NIRS cyclotrons are to be presented in this report.

An isotope Separation On-Line (ISOL) system for radioactive C-11 ion beam acceleration is expected to be realized for a PET imaging simultaneously with the heavy-ion cancer therapy. In the ISOL scheme, C-11 molecules are firstly produced by irradiating boron compound target with proton beams (20 MeV, ~30 μA) provided by a small cyclotron. The C-11 molecules are separated from impurity molecules mixed into the target chamber during the proton irradiation. Then, 1+ ions are firstly produced from the purified C-11 molecules with the singly charged ion source. Finally, after the isotope separation with an analyzing magnet, the C+ ions are further ionized by employing an EBIS as a charge breeder to obtain required charge state for the HIMAC injector.* We have been developed a C-11 molecular production/separation system to produce the C-11 molecules and separate it from the impurities. We have also been developed a new singly charged ion source to produce the 1+ ions.
