The experiments were carried out utilizing Fe ion beams from Heavy Ion Medical Accelerator (HIMAC). Changes in the track registration sensitivity with temperature were studied at temperatures between 213 and 293 K. The charge and mass shifts around Fe ions are possibly 0.11 cu (charge unit) and 0.47 amu (atomic mass unit) at the temperature deviation between 227 and 243 K at balloon altitude. Decrease in track registration sensitivity as air pressure decreases has been observed between 13 Pa and 27 kPa. The charge and mass shifts around Fe ions are inferred to be 0.02 cu and 0.09 amu, respectively, when pressure varies between 20 and 27 kPa. During balloon flight, air pressure drops below this; therefore, care must be taken to keep the temperature and air pressure of CR-39 detectors within acceptable limits.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-583X","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":"Kodaira, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"452174","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Nakahiro"}],"nameIdentifiers":[{"nameIdentifier":"452175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tawara, Hiroko"}],"nameIdentifiers":[{"nameIdentifier":"452176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Kouichi"}],"nameIdentifiers":[{"nameIdentifier":"452177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Doke, Tadayoshi"}],"nameIdentifiers":[{"nameIdentifier":"452178","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasebe, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"452179","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Tomoya"}],"nameIdentifiers":[{"nameIdentifier":"452180","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小平 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452181","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安田 仲宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452182","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山内 知也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452183","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":"Temperature and pressure conditions for the appropriate performance of charge and mass resolutions in balloon-borne CR-39 track detector for the heavy cosmic rays","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temperature and pressure conditions for the appropriate performance of charge and mass resolutions in balloon-borne CR-39 track detector for the heavy cosmic rays"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-05-14"},"publish_date":"2009-05-14","publish_status":"0","recid":"45507","relation_version_is_last":true,"title":["Temperature and pressure conditions for the appropriate performance of charge and mass resolutions in balloon-borne CR-39 track detector for the heavy cosmic rays"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:02:55.674021+00:00"}
