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. Moreover, a test irradiation port is being constructed at NIRS AVF930 cyclotron facility for on-line experiments to produce C-11 ions. Latest results on those developments and prospects of our ISOL scheme are to be presented.","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":"HIAT 2015","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":"片桐, 健"}],"nameIdentifiers":[{"nameIdentifier":"647591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"al., et"}],"nameIdentifiers":[{"nameIdentifier":"647592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"片桐 健","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"647593","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":"Research and developments toward radioactive 11C ion acceleration","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Research and developments toward radioactive 11C ion acceleration"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-09-15"},"publish_date":"2015-09-15","publish_status":"0","recid":"65747","relation_version_is_last":true,"title":["Research and developments toward radioactive 11C ion acceleration"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:56:43.723261+00:00"}
