Electro-optic diagnostics on the Coulomb fields of electron beams have the advantages of single shot and non-destructive characteristics.1,2 We present a study of introducing the electro-optic spatial decoding technique3 to laser wakefield acceleration (LWFA)4. \nTo determine the time scale of the observed signal, a temporal mapping relationship is necessary.  By placing an electro-optic crystal very close to a gas target, we discovered that the Coulomb field of the electron bunch possessed a spherical structure that was inconsistent with the previously widely used model. The field structure was demonstrated by experimental measurement, analytic calculations and simulations. A new temporal mapping relationship with generality was derived in a geometry where the signals had spherical wavefronts5. This study could be helpful for the applications of electro-optic diagnostics in laser plasma acceleration experiments.\n    This work was funded by ImPACT Program of Council for Science, Technology and Innovation (Cabinet Office, Government of Japan).","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":"HEDS2018","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":"黄, 開"}],"nameIdentifiers":[{"nameIdentifier":"656866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Timur, Esirkepov"}],"nameIdentifiers":[{"nameIdentifier":"656867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kevin, Koga James"}],"nameIdentifiers":[{"nameIdentifier":"656868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotaki, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"656869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mori, Michiaki"}],"nameIdentifiers":[{"nameIdentifier":"656870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayashi, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"656871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanii, Nobuhiko"}],"nameIdentifiers":[{"nameIdentifier":"656872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey"}],"nameIdentifiers":[{"nameIdentifier":"656873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kando, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"656874","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黄 開","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656875","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"エシロケポフ ティムル","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"コーガ ジェームズ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656877","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小瀧 秀行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656878","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 道昭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656879","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林 由紀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656880","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中新 信彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656881","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ブラノフ セルゲイ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656882","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神門 正城","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656883","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":"Electro-optic spatial decoding on the spherical-wavefront Coulomb fields of plasma electron sources","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Electro-optic spatial decoding on the spherical-wavefront Coulomb fields of plasma electron sources"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-07"},"publish_date":"2018-05-07","publish_status":"0","recid":"66805","relation_version_is_last":true,"title":["Electro-optic spatial decoding on the spherical-wavefront Coulomb fields of plasma electron sources"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:44:42.680314+00:00"}
