Although nuclear emulsions, which record the three-dimensional trajectories of charged particles, feature high sensitivity and a sub-micron spatial resolution, they have never been used for the detection of laser-accelerated ions. This is because intense laser-matter interactions generate not only ions but also copious electrons, including secondary electrons induced by X-rays, which are recorded as background noise in a nuclear emulsion. Therefore, it is not a trivial task to identify ion tracks in a nuclear emulsion exposed to such extreme mixed radiation  elds. Here, for the  rst time, we have succeeded in identifying the signals from laser-accelerated protons in nuclear emulsions by suppressing the background noise signals through the use of desensitized development conditions, i.e., a developer solution with a pH of 7.3 and a development time of 25 min. The energy spectrum obtained from a stack of nuclear emulsion  lms shows good agreement with that obtained from a stack of  lms of the con- ventional solid-state nuclear track detector material CR-39, which is sensitive only to ions. An additional benchmark experiment with 100-MeV protons from a conventional accelerator apparatus con rms that nuclear emulsions have the potential to measure 100-MeV-class laser-accelerated protons.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.hedp.2019.04.002","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.hedp.2019.04.002","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1574-1818","subitem_source_identifier_type":"ISSN"}]},"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":"Asai, Takafumi"}],"nameIdentifiers":[{"nameIdentifier":"1070612","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanasaki, Masato"}],"nameIdentifiers":[{"nameIdentifier":"1070613","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jinno, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"1070614","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitagawa, Nobuko"}],"nameIdentifiers":[{"nameIdentifier":"1070615","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shutoh, Nobumichi"}],"nameIdentifiers":[{"nameIdentifier":"1070616","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodaira, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"1070617","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Tomoya"}],"nameIdentifiers":[{"nameIdentifier":"1070618","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Keiji"}],"nameIdentifiers":[{"nameIdentifier":"1070619","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morishima, Kunihiro"}],"nameIdentifiers":[{"nameIdentifier":"1070620","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuda, Yuuji"}],"nameIdentifiers":[{"nameIdentifier":"1070621","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takafumi, Asai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoshi, Kodaira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuji, Fukuda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070624","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":"Application of nuclear emulsions for the identification of multi-MeV protons in laser ion acceleration experiments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of nuclear emulsions for the identification of multi-MeV protons in laser ion acceleration experiments"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-10"},"publish_date":"2019-06-10","publish_status":"0","recid":"76014","relation_version_is_last":true,"title":["Application of nuclear emulsions for the identification of multi-MeV protons in laser ion acceleration experiments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T16:45:53.846393+00:00"}
