Betatron x-rays are usually produced via self-injected electron beams, which are not controllable and are not optimized for x-ray yields. Here, we present a\nnew method for bright hard x-ray emission via ionization injection from the K-shell electrons of nitrogen into the accelerating bucket. A total photon yield of 8 × 108/shot and 108 photons with energy greater than 110 keV is obtained. The yield is 10 times higher than that achieved with self-injection mode in helium under similar laser parameters. The simulation suggests that ionization- injected electrons are quickly accelerated to the driving laser region and are subsequently driven into betatron resonance. The present scheme enables the single-stage betatron radiation from LWFA to be extended to bright γ-ray radiation, which is beyond the capability of 3rd generation synchrotrons.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature Publishing Group"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/srep27633","subitem_relation_type_select":"DOI"}}]},"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":"ホァン, カイ"}],"nameIdentifiers":[{"nameIdentifier":"482164","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Y.F.Li"}],"nameIdentifiers":[{"nameIdentifier":"482165","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"D.Z.Li"}],"nameIdentifiers":[{"nameIdentifier":"482166","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"L.M.Chen"}],"nameIdentifiers":[{"nameIdentifier":"482167","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M.Z.Tao"}],"nameIdentifiers":[{"nameIdentifier":"482168","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Y.Ma"}],"nameIdentifiers":[{"nameIdentifier":"482169","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"J.R.Zhao"}],"nameIdentifiers":[{"nameIdentifier":"482170","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M.H.Li"}],"nameIdentifiers":[{"nameIdentifier":"482171","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M.Chen"}],"nameIdentifiers":[{"nameIdentifier":"482172","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M.Mirzaie"}],"nameIdentifiers":[{"nameIdentifier":"482173","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"N.Hafz"}],"nameIdentifiers":[{"nameIdentifier":"482174","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sokollik, T."}],"nameIdentifiers":[{"nameIdentifier":"482175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Z.M.Sheng"}],"nameIdentifiers":[{"nameIdentifier":"482176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"J.Zhang"}],"nameIdentifiers":[{"nameIdentifier":"482177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黄 開","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"482178","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":"Resonantly Enhanced Betatron Hard X-rays from Ionization Injected Electrons in a Laser Plasma Accelerator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Resonantly Enhanced Betatron Hard X-rays from Ionization Injected Electrons in a Laser Plasma Accelerator"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-06-06"},"publish_date":"2017-06-06","publish_status":"0","recid":"48029","relation_version_is_last":true,"title":["Resonantly Enhanced Betatron Hard X-rays from Ionization Injected Electrons in a Laser Plasma Accelerator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:32:48.220292+00:00"}
