From studies of the scanning method, it has been required for a medical synchrotron to be capable of controlling the beam intensity during the duration of extraction. For this purpose, a beam-intensity control technique with RF-knockout slow-extraction has been studied and developed at the HIMAC synchrotron. Based on a simple one-dimensional model of extraction, the function of amplitude modulation (AM) for a transverse RF-field was analytically calculated to control the beam current. By cooperating with the feedback system, finally, we could control the beam intensity within a range of one order during a single flattop. We report on a simulation and the experiment result of intensity control for scanning irradiation.","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":"Furukawa, Takuji"}],"nameIdentifiers":[{"nameIdentifier":"435781","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noda, Kouji"}],"nameIdentifiers":[{"nameIdentifier":"435782","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uesugi, Takehiro"}],"nameIdentifiers":[{"nameIdentifier":"435783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Naruse, Takuya"}],"nameIdentifiers":[{"nameIdentifier":"435784","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"435785","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古川 卓司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435786","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野田 耕司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435787","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"上杉 健弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"435788","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":"Intensity control in RF-knockout extraction for scanning irradiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Intensity control in RF-knockout extraction for scanning irradiation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-10-22"},"publish_date":"2005-10-22","publish_status":"0","recid":"43833","relation_version_is_last":true,"title":["Intensity control in RF-knockout extraction for scanning irradiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:22:31.978080+00:00"}
