Because of the interaction between the\nelectron beam and FEL electromagnetic field, a maximum electron energy\ndecrease of 16% was observed. The measured energy decrease was\nconsistent with the measured FEL spectrum. An FEL micro-pulse energy\nof approximately 100 micro-J with micro-pulse duration of 150 fs was\nobserved. This result is an important milestone for the\nhigh-extraction-efficiency FEL oscillator and will contribute to the\nstrong-field physics of atoms and molecules.","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 12th International Particle Accelerator Conference - IPAC’21","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":"全炳俊"}],"nameIdentifiers":[{"nameIdentifier":"1036751","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大垣英明"}],"nameIdentifiers":[{"nameIdentifier":"1036752","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryoichi, Hajima"}],"nameIdentifiers":[{"nameIdentifier":"1036753","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryoichi, Hajima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1036754","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":"Record High Extraction Efficiency of Free electron Laser Oscillator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Record High Extraction Efficiency of Free electron Laser Oscillator"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-05-13"},"publish_date":"2021-05-13","publish_status":"0","recid":"85887","relation_version_is_last":true,"title":["Record High Extraction Efficiency of Free electron Laser Oscillator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:31:18.763206+00:00"}
