The purpose of the present study is to show how obtain a suitable beam intensity of the 11C-beam extracted from the HIMAC-Synchrotron. In connection with this study, related developments include the production of radioactive isotopes (11C) by cyclotron, gas separation, gas-compression, gas-pulsing and ionization. Further, the residue 11CO2-gas can be reproduced in the ionization process. As the result of a calculation, the order of 108ppp of 11C6+ ions can be extracted from the HIMAC-synchrotron during 18 minutes at 3.3-second intervals with a 1-msec beam pulse under the assumption of that 1Ci of 11C-production. Details of the study are presented.","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":"8th European Conference on Accelerators in Applied Research and Technology","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":"Houjou, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"666869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北條 悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666870","nameIdentifierScheme":"WEKO"}]}]},"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":"A Study of 11C-beam Adopting to Particle Therapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Study of 11C-beam Adopting to Particle Therapy"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-09-28"},"publish_date":"2004-09-28","publish_status":"0","recid":"67887","relation_version_is_last":true,"title":["A Study of 11C-beam Adopting to Particle Therapy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:32:34.909319+00:00"}
