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.}, title = {Progress on the Upgrade for TRT at NIRS Cyclotron Facility}, year = {2015} }
