A solid-state track detector such as CR-39 has the advantage of easy extension of exposure area, but it is necessary to raise the Z/beta detection threshold in order to suppress background tracks produced by galactic cosmic rays with Z/beta<30. The track registration sensitivity and detection threshold for heavy ions with various Z*/beta were verified by using track detectors of copolymers of CR-39 and DAP (diallyl phthalate) with various DAP concentration. We found that it is possible to control the Z*/beta detection\nthreshold of copolymers by changing DAP concentration. In order to detect heavy ions with Z*/beta > 30, the optimum DAP concentration was\nfound to be approximately 50%.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1350-4487","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":"450829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Doke, Tadayoshi"}],"nameIdentifiers":[{"nameIdentifier":"450830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasebe, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"450831","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Kouichi"}],"nameIdentifiers":[{"nameIdentifier":"450832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Nakahiro"}],"nameIdentifiers":[{"nameIdentifier":"450833","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuruta, Takao"}],"nameIdentifiers":[{"nameIdentifier":"450834","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"450835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小平 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450836","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"道家 忠義","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450837","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安田 仲宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450838","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鶴田 隆雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"450839","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":"Track detector of CR-39-DAP-copolymer with variable threshold to detect trans-iron nuclei in galactic cosmic rays","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Track detector of CR-39-DAP-copolymer with variable threshold to detect trans-iron nuclei in galactic cosmic rays"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-01-05"},"publish_date":"2009-01-05","publish_status":"0","recid":"45384","relation_version_is_last":true,"title":["Track detector of CR-39-DAP-copolymer with variable threshold to detect trans-iron nuclei in galactic cosmic rays"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:04:21.611146+00:00"}
