In this irradiation, we have adopted a raster scan method to make the lateral dose distribution. For the reduction of the difference between prescribed and delivered dose distribution, it is preferable that the extracted beam-current from the synchrotron ring is low ripple, and the response to the beam-on/off switching is quick. To meet these requirements, we have developed a new beam-intensity control system with the RF-knockout slow extraction and feedback control system. In the system commissioning, we can modulate the beam-intensity in the range of thirty times while keeping the beam-current ripple below 20%.","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":"第8回日本加速器学会年会","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":"水島, 康太"}],"nameIdentifiers":[{"nameIdentifier":"694347","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水島 康太","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"694348","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"HIMAC新ビーム強度制御システムのコミッショニング","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"HIMAC新ビーム強度制御システムのコミッショニング"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-23"},"publish_date":"2012-02-23","publish_status":"0","recid":"70688","relation_version_is_last":true,"title":["HIMAC新ビーム強度制御システムのコミッショニング"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:00:01.720062+00:00"}
