The gun system consists of an alkali antimonide photocathode preparation chamber, a dc gun with a 250 kV-50 mA Cockcroft-Walton high-voltage power supply, and a downstream beamline with a water-cooled beam dump to accommodate a beam power of 5 kW. We fabricated a Cs3Sb photocathode with quantum efficiency of 5.8% at a wavelength of 532 nm and generated a 150 keV beam with current of up to 4.3 mA with a 500 mW laser. A vacuum chamber for the Smith-Purcell free-electron laser has been installed in the downstream beamline. We describe the present status of our work.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/particles1010012 ","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.mdpi.com/2571-712X/1/1/12/htm"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.mdpi.com/2571-712X/1/1/12/htm","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":"Nishimori, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"723731","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagai, Ryoji"}],"nameIdentifiers":[{"nameIdentifier":"723732","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sawamura, Masaru"}],"nameIdentifiers":[{"nameIdentifier":"723733","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hajima, Ryoichi"}],"nameIdentifiers":[{"nameIdentifier":"723734","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西森 信行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"723735","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"永井 良治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"723736","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"沢村 勝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"723737","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽島 良一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"723738","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Development of a multialkali photocathode dc gun for a Smith-Purcell terahertz free-electron laser","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a multialkali photocathode dc gun for a Smith-Purcell terahertz free-electron laser"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-18"},"publish_date":"2019-02-18","publish_status":"0","recid":"49418","relation_version_is_last":true,"title":["Development of a multialkali photocathode dc gun for a Smith-Purcell terahertz free-electron laser"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:29:40.959092+00:00"}
