Koga and Hayakawa [1] have presented that it is possible to measure selectively the amplitude of Delbrück scattering using linearly polarized gamma-ray beams. Furthermore, if one uses a linearly polarized beam with energies lower than 1.022 MeV, which is the threshold of the pair creation, it is possible to measure only the virtual process of Delbrück Scattering, namely vacuum polarization. For such a purpose, we have developed a laser Compton scattering (LCS) gamma-ray beam with a CO2 laser having a wavelength of 10 micro m at the UVSOR-III synchrotron radiation facility, in which the energy of the electron beam stored in top-up mode is approximately 750 MeV. We generated a 1-MeV LCS gamma-ray beam. We will also discuss future plans.","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":"Nuclear Photonics 2018","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":"Hayakawa, Takehito"}],"nameIdentifiers":[{"nameIdentifier":"717983","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuma, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"717984","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"K., Koga Jame"}],"nameIdentifiers":[{"nameIdentifier":"717985","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zen, Heishun"}],"nameIdentifiers":[{"nameIdentifier":"717986","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kii, Toshiteru"}],"nameIdentifiers":[{"nameIdentifier":"717987","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohgaki, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"717988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujimoto, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"717989","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"717990","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早川 岳人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717991","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"静間 俊行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717992","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"コーガ ジェームズ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717993","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":"Laser Compton scattering gamma-ray generation for Delbrück scattering experiments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Laser Compton scattering gamma-ray generation for Delbrück scattering experiments"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-07-17"},"publish_date":"2018-07-17","publish_status":"0","recid":"72867","relation_version_is_last":true,"title":["Laser Compton scattering gamma-ray generation for Delbrück scattering experiments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:35:13.339543+00:00"}
