The NIRS-930 has been used for production of short-lived radio-pharmaceuticals for Positron Emission Tomography (PET), research of physics, developments of particle detectors in space, and so on. The orbit of a beam in the NIRS-930 cyclotron was simulated with integrated approach for modelling of the cyclotron, including calculation of electromagnetic fields of the structural elements. And some improvements such as installation of extracted beam probe, a beam attenuator and a beam viewer in an injection beam line, were performed in the NIRS-930. The HM-18 has been used for production of short-lived radio-pharmaceuticals for PET. It provides us accelerated H-and D- ions at fixed energies of 18 and 9 MeV, respectively. In order to improve the isochronisms, a phase probe has been newly installed in the HM-18. Operational status of the cyclotron facilities and their improvements are to be presented in this report.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"20th International Conference on Cyclotrons and their Applications","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Houjou, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"700792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北條 悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700793","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"PRESENT STATUS OF CYCLOTRONS (NIRS-930, HM-18) AT NIRS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PRESENT STATUS OF CYCLOTRONS (NIRS-930, HM-18) AT NIRS"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-10-10"},"publish_date":"2013-10-10","publish_status":"0","recid":"71283","relation_version_is_last":true,"title":["PRESENT STATUS OF CYCLOTRONS (NIRS-930, HM-18) AT NIRS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:53:02.757065+00:00"}
