A steady state sodium plasma was produced by primary electrons in a sodium gas evaporating from a metal sample placed in the discharge chamber. The Na^- current density of I.5 muA/cm^2 was obtained from a single aperture of 1.5 mm diameter at relatively low discharge power of about 0.4 W and filament power of 50 W. Extraction characteristics were studied by changing the plasma electrode bias. The extracted Na^- current showed dependence on the bias voltage similar to that of H^- or Li^- volume production.","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-035"}]},"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":"\"Sasao,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaoka,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wada,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita,  J.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"negative ion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sodium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"volume production","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Iithium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion source","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Direct Extraction of a Na- Beam from a Sodium Plasma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Direct Extraction of a Na- Beam from a Sodium Plasma","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10183","relation_version_is_last":true,"title":["Direct Extraction of a Na- Beam from a Sodium Plasma"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:52:39.434954+00:00"}
