The application of beta-delayed particle decay beams like 9C ions in cancer therapy is expected to further improve the treatment efficacy of the modality of heavy-ions.  For the first time 9C beams were produced in the secondary beam line (SBL) of the HIMAC facility with a primary 12C beam of 430 MeV/n.  The production conditions providing a 9C beam with higher production rate and purity were optimized using different thick production targets and degraders.  The results show setting the momentum acceptance to the full value of 5% the production rate is 9.07 x 10^-6^ and the purity is 82.88% for the produced 9C beam under the optimal condition.  Because of the large momentum spread for a secondary beam, the momentum distribution of the produced 9C beam at the optimal condition was measured.  The momentum among the beam had a nearly Gaussian profile with a standard deviation of 26.1 MeV/c/n and the largest component of the momenta appeared around 838.9 MeV/c/n.  In order to form a relatively large uniform irradiation field being apppropriate to further biologicl experiments for the produced 9C beam, the scanning magnets in the irradiation system of the SBL, operating in a wobbling mode, was use.  A uniform irradiation field of 20 mm in diameter could be achieved with homogeneity of 93.3%.  The work presented in this paper provides a substantial basis for the further studies with 9C beams for the therapeutic purpose.","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":"Li, Qiang"}],"nameIdentifiers":[{"nameIdentifier":"435438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitagawa, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"435439","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanai, Tatsuaki"}],"nameIdentifiers":[{"nameIdentifier":"435440","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanazawa, Mitsutaka"}],"nameIdentifiers":[{"nameIdentifier":"435441","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Urakabe, Eriko"}],"nameIdentifiers":[{"nameIdentifier":"435442","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomitani, Takehiro"}],"nameIdentifiers":[{"nameIdentifier":"435443","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satou, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"435444","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Wei"}],"nameIdentifiers":[{"nameIdentifier":"435445","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"李 強","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435446","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北川 敦志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435447","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金井 達明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435448","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金澤 光隆","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435449","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新谷 恵理子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435450","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"富谷 武浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435451","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤 眞二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 偉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435453","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":"Therapeutic purpose 9C beams produced in the secondary beam line at HIMAC","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Therapeutic purpose 9C beams produced in the secondary beam line at HIMAC"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-09-13"},"publish_date":"2005-09-13","publish_status":"0","recid":"43798","relation_version_is_last":true,"title":["Therapeutic purpose 9C beams produced in the secondary beam line at HIMAC"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:22:56.024065+00:00"}
