The main ion species used are protons and helium for these experiments. In addition, heavy ions such as carbon and neon are also supplied. These ions are produced by the compact ECR ion source with all permanent magnets (Kei-source). The Kei-source is installed on top of the NIRS-930, and the ions extract from the ion source pass through the low-energy beamline and enter the NIRS-930. In the future, the ion source will be required to produce highly charged ions of various ion species and increase the beam intensity. The Kei-source has not been optimized for the position of the extraction electrode because a sufficient beam current was obtained. In the case of He2+, the transmission efficiency from faraday cup 2 (FC2) and faraday cup 3 (FC3) was about 60%. In this study, the position of the extraction electrode was optimized and the beam transmission efficiency of the low-energy beam transport will be improved by remotely controlling the extraction electrode of Kei-source. The distance of the extraction electrode and the plasma electrode can be change 28- 54 mm. As a result of a beam test with He2+, the transmission efficiency of FC2-FC3 increased to 93% when the distance of extraction electrode and plasma electrode was changed.","subitem_description_type":"Abstract"}]},"item_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.pasj.jp/web_publish/pasj2021/proceedings/PDF/WEP0/WEP058.pdf","subitem_relation_type_select":"URI"}}]},"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":"村松, 正幸"}],"nameIdentifiers":[{"nameIdentifier":"1021955","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神谷, 隆(AEC)"}],"nameIdentifiers":[{"nameIdentifier":"1021956","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡田, 高典(AEC)"}],"nameIdentifiers":[{"nameIdentifier":"1021957","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"片桐, 健"}],"nameIdentifiers":[{"nameIdentifier":"1021958","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"杉浦, 彰則"}],"nameIdentifiers":[{"nameIdentifier":"1021959","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北條, 悟"}],"nameIdentifiers":[{"nameIdentifier":"1021960","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"涌井, 崇志"}],"nameIdentifiers":[{"nameIdentifier":"1021961","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masayuki, Muramatsu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1021962","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken, Katagiri","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1021963","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akinori, Sugiura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1021964","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoru, Hojo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1021965","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takashi, Wakui","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1021966","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"小型 ECR イオン源の引出電極位置の最適化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小型 ECR イオン源の引出電極位置の最適化"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-01-12"},"publish_date":"2022-01-12","publish_status":"0","recid":"84677","relation_version_is_last":true,"title":["小型 ECR イオン源の引出電極位置の最適化"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:16:13.943929+00:00"}
