The CR-39 detectors, which are the most sensitive solid state nuclear track detectors (SSNTD), have been used for long time to understand the both of spatial distributions and energy spectra of laser-accelerated ions. In such a situation, we have studied the applicability of a nuclear emulsion as the alternative ion detector for laser-accelerated ions. In the laser-driven ion acceleration experiments, not only ions, but also copious energetic electrons and X rays are simultaneously generated. Threfore, to suppress the background noise signals from the electrons and X rays, pH level of the developer and the development time of a nuclear emulsion are optimized. As a result, we have for the first time succeeded in identifying the signals from laser-accelerated protons up to 11.5 MeV and obtained an energy spectrum. The spectrum shows a good agreement with that obtained by CR-39.","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":"第2回QST国際シンポジウム","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":"Takafumi, Asai"}],"nameIdentifiers":[{"nameIdentifier":"720976","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanasaki, Masato"}],"nameIdentifiers":[{"nameIdentifier":"720977","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jinno, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"720978","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shutoh, Nobumichi"}],"nameIdentifiers":[{"nameIdentifier":"720979","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Tomoya"}],"nameIdentifiers":[{"nameIdentifier":"720980","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Keiji"}],"nameIdentifiers":[{"nameIdentifier":"720981","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morishima, Kunihiro"}],"nameIdentifiers":[{"nameIdentifier":"720982","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuda, Yuuji"}],"nameIdentifiers":[{"nameIdentifier":"720983","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅井 孝文","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720984","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金崎 真聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720985","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神野 智史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720986","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山内 知也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720987","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田 啓二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森島 邦博","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720989","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福田 祐仁","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"720990","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":"Energy measurement of laser-accelerated protons by using a nuclear emulsion","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Energy measurement of laser-accelerated protons by using a nuclear emulsion"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-21"},"publish_date":"2019-01-21","publish_status":"0","recid":"73160","relation_version_is_last":true,"title":["Energy measurement of laser-accelerated protons by using a nuclear emulsion"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:32:15.872523+00:00"}
