An advantage of this system, with utilized to the injection line, is to that it allows high-current ion-beam extraction from an ECR-ion source, because it can be operated with a large potential difference between the source and the extractor. The deceleration system is operated at a negative DC-voltage of around -10 kV, which is applied to the extractor and reduced to the ground potential by the decelerator. An electric field in the deceleration system was carefully designed by using a 3-dimensional field simulator. About a five-times intensity increase has been obtained for a 12C4+ beam at the cyclotron exit, as compared with the case where the new system is not used. Design studies of the decelerator as well as the result of a beam test are 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":"第11回イオン源国際会議（ＩＣＩＳ−05）","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":"Honma, Toshihiro"}],"nameIdentifiers":[{"nameIdentifier":"669314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"本間 壽廣","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"669315","nameIdentifierScheme":"WEKO"}]}]},"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":"Low-energy Ion Decelerator for an External injection line at the NIRS-930 Cyclotron","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Low-energy Ion Decelerator for an External injection line at the NIRS-930 Cyclotron"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-09-27"},"publish_date":"2005-09-27","publish_status":"0","recid":"68167","relation_version_is_last":true,"title":["Low-energy Ion Decelerator for an External injection line at the NIRS-930 Cyclotron"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:29:19.522536+00:00"}
