Electro-optic diagnostics on the Coulomb fields of electron beams have the advantages of single shot and non-destructive characteristics. We present a study of introducing the electro-optic spatial decoding technique to laser wakefield acceleration (LWFA). \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 and 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 wavefronts. This study could be helpful for the applications of electro-optic diagnostics in laser plasma acceleration experiments.","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 2nd QST International Symposium","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":"720297","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小瀧, 秀行"}],"nameIdentifiers":[{"nameIdentifier":"720298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森, 道昭"}],"nameIdentifiers":[{"nameIdentifier":"720299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"エシロケポフ, ティムル"}],"nameIdentifiers":[{"nameIdentifier":"720300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"コーガ, ジェームズ"}],"nameIdentifiers":[{"nameIdentifier":"720301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林, 由紀雄"}],"nameIdentifiers":[{"nameIdentifier":"720302","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中新, 信彦"}],"nameIdentifiers":[{"nameIdentifier":"720303","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ブラノフ, セルゲイ"}],"nameIdentifiers":[{"nameIdentifier":"720304","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神門, 正城"}],"nameIdentifiers":[{"nameIdentifier":"720305","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黄 開","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720306","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小瀧 秀行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 道昭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"エシロケポフ ティムル","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720309","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"コーガ ジェームズ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"林 由紀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720311","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中新 信彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720312","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ブラノフ セルゲイ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神門 正城","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720314","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":"Clocking the electron bunches from laser wakefield acceleration via EO sampling method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Clocking the electron bunches from laser wakefield acceleration via EO sampling method"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-18"},"publish_date":"2018-12-18","publish_status":"0","recid":"73100","relation_version_is_last":true,"title":["Clocking the electron bunches from laser wakefield acceleration via EO sampling method"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:32:52.843621+00:00"}
