For such applications, the timing jitter and the bunch duration of the electron bunches are important parameters that are barely investigated experimentally.\nWe established electro-optic sampling techniques [6] adequate for the diagnostics of electron temporal information in laser wakefield acceleration (LWFA) [2]. For the investigation of electron timing jitter and injection process, electro-optic spatial decoding (EOSD) on the electron Coulomb field was performed. The spherical wavefront of the Coulomb field and plasma-density-dependent electron emission timing were discovered [7,8,9]. For the determination of electron bunch durations, EOSD on the coherent transition radiation (CTR) produced when electrons passing through a metal foil was conducted. An electron beam peak current up to 10 kA was demonstrated.\nThis research not only showed the capability of EO sampling serving as a real-time electron temporal diagnostic for laser-driven sources but also demonstrated the ultra-fast and high-brightness nature of laser-driven electron sources for various applications.\n","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":"The 30th International Toki Conference on Plasma and Fusion Research","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":"HUANG, KAI"}],"nameIdentifiers":[{"nameIdentifier":"1011438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hideyuki, Kotaki"}],"nameIdentifiers":[{"nameIdentifier":"1011439","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Michiaki, Mori"}],"nameIdentifiers":[{"nameIdentifier":"1011440","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Timur, Esirkepov"}],"nameIdentifiers":[{"nameIdentifier":"1011441","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kevin Koga, James"}],"nameIdentifiers":[{"nameIdentifier":"1011442","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yukio, Hayashi"}],"nameIdentifiers":[{"nameIdentifier":"1011443","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuhiko, Nakanii"}],"nameIdentifiers":[{"nameIdentifier":"1011444","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jin, Zhan"}],"nameIdentifiers":[{"nameIdentifier":"1011445","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomonao, Hosokai"}],"nameIdentifiers":[{"nameIdentifier":"1011446","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaki, Kando"}],"nameIdentifiers":[{"nameIdentifier":"1011447","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HUANG, KAI","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011448","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hideyuki, Kotaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011449","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Michiaki, Mori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011450","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Timur, Esirkepov","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011451","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kevin Koga, James","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yukio, Hayashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011453","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuhiko, Nakanii","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011454","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jin, Zhan","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011455","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomonao, Hosokai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011456","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaki, Kando","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011457","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":"Temporal characterization of laser driven ultrafast electron bunches via electro-optic sampling","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal characterization of laser driven ultrafast electron bunches via electro-optic sampling"}]},"item_type_id":"10005","owner":"1","path":["27"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-18"},"publish_date":"2021-11-18","publish_status":"0","recid":"83834","relation_version_is_last":true,"title":["Temporal characterization of laser driven ultrafast electron bunches via electro-optic sampling"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:00:11.239972+00:00"}
