量研学術機関リポジトリ「QST-Repository」は、国立研究開発法人 量子科学技術研究開発機構に所属する職員等が生み出した学術成果(学会誌発表論文、学会発表、研究開発報告書、特許等)を集積しインターネット上で広く公開するサービスです。 Welcome to QST-Repository where we accumulates and discloses the academic research results(Journal Publications, Conference presentation, Research and Development Report, Patent, etc.) of the members of National Institutes for Quantum Science and Technology.
Thank you very much for using our website. On the 11th of March 2019, this site was moved from our own network server to the JAIRO Cloud network server.

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.
