Since the resonance energy of nuclei is unique, NRF could be used as a fingerprint of each isotope for assay. In the proposed method, a photon beam generated by laser Compton scattering (LCS) between laser light and high energy electrons is used to excite a nucleus via NRF. The LCS photon beam has several advanced characteristics in its energy tunability, narrow energy width, and small divergence. Since high energy gamma-rays in a MeV energy range used in the proposed method can penetrate thick materials, this method could be applied to nondestructive detection of nuclear materials hidden in thick heavy shielding materials such as a cargo container. So far, we have implemented a research and development program of the LCS gamma-ray NDA which includes the demonstration of intense LCS photon generation from energy recovery linac (ERL), establishment of NRF measurement methods, benchmark test of Monte Carlo simulation code. We will present the results and status of our R&D program, which has been implemented under the subsidiary for nuclear security promotion of MEXT (Ministry of Education, Culture, Sports, Science and Technology - 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":"the 2nd Technical Meeting on Radiation Detection Instruments for Nuclear Security","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":"静間, 俊行"}],"nameIdentifiers":[{"nameIdentifier":"716569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽島, 良一"}],"nameIdentifiers":[{"nameIdentifier":"716570","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"アブデルサナド, モハマドオマルナギー"}],"nameIdentifiers":[{"nameIdentifier":"716571","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小泉, 光生"}],"nameIdentifiers":[{"nameIdentifier":"716572","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"瀬谷, 道夫"}],"nameIdentifiers":[{"nameIdentifier":"716573","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"静間 俊行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716574","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽島 良一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716575","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"アブデルサナド モハマドオマルナギー","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716576","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"Development of the isotope-specific nondestructive assay method based on nuclear resonance fluorescence","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of the isotope-specific nondestructive assay method based on nuclear resonance fluorescence"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-25"},"publish_date":"2018-04-25","publish_status":"0","recid":"72753","relation_version_is_last":true,"title":["Development of the isotope-specific nondestructive assay method based on nuclear resonance fluorescence"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:36:26.650491+00:00"}
