Because it can generate an extreme electric field that is over six orders of magnitude higher than that of a conventional radio-frequency accelerator apparatus. To understand the underlying physics of the acceleration process and increase maximum proton energy, precise measurement of both the energy spectrum and the two-dimensional distribution is required. Against this background, we have developed a new measurement method for laser-accelerated sub-GeV-class protons using the nuclear emulsion. Based on the Multiple Coulomb Scattering (MCS) method in an Emulsion Cloud Chamber (ECC), which is a stack of nuclear emulsion films and scatterer plates, the incident energies were inversely evaluated by the scattering angle. The proof-of-principle experiment has been conducted with the Heavy-Ion Medical Accelerator in Chiba (HIMAC) to verify that the ECC is able to identify sub-GeV protons with the MCS method. Combined with a technique of machine learning, a new measurement method has been developed to obtain an energy spectrum of laser-accelerated sub-GeV protons by the ECC with the MCS method.","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":"ICMaSS2021","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":"1070319","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanasaki, Masato"}],"nameIdentifiers":[{"nameIdentifier":"1070320","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuko, Kitagawa"}],"nameIdentifiers":[{"nameIdentifier":"1070321","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobumichi, Shutoh"}],"nameIdentifiers":[{"nameIdentifier":"1070322","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoshi, Kodaira"}],"nameIdentifiers":[{"nameIdentifier":"1070323","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomoya, Yamauchi"}],"nameIdentifiers":[{"nameIdentifier":"1070324","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiji, Oda"}],"nameIdentifiers":[{"nameIdentifier":"1070325","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kunihiro, Morishima"}],"nameIdentifiers":[{"nameIdentifier":"1070326","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuji, Fukuda"}],"nameIdentifiers":[{"nameIdentifier":"1070327","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takafumi, Asai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070328","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoshi, Kodaira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070329","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuji, Fukuda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1070330","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":"Development of the New Method to Measure Laser-accelerated Sub-GeV Protons Utilizing Multiple Coulomb Scattering in an Emulsion Cloud Chamber","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of the New Method to Measure Laser-accelerated Sub-GeV Protons Utilizing Multiple Coulomb Scattering in an Emulsion Cloud Chamber"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-26"},"publish_date":"2021-10-26","publish_status":"0","recid":"83806","relation_version_is_last":true,"title":["Development of the New Method to Measure Laser-accelerated Sub-GeV Protons Utilizing Multiple Coulomb Scattering in an Emulsion Cloud Chamber"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T16:46:58.105915+00:00"}
