The multiple-energy synchrotron operation with stepwise flattops has been developed at HIMAC in NIRS, in order to perform scanning irradiation without using the energy degrader which increases the beam size by the multiple scattering. The operation can vary the extraction beam energy quickly from 430 to 56 MeV/n by gradually decelerating the stored beam in the synchrotron ring. The number of the energy steps required from the scanning irradiation system is about 200. To meet the requirement with a shorter commissioning time, we proposed a method to determine the beam- and device-parameter settings for all energies by an interpolation method. As a result, it was confirmed that it is possible to produce the multiple-energy operation having many energy steps by small manual adjustments for less energy steps.","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10回 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":"700009","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水島 康太","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700010","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における可変エネルギー運転の高度化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"HIMACにおける可変エネルギー運転の高度化"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-13"},"publish_date":"2013-08-13","publish_status":"0","recid":"71207","relation_version_is_last":true,"title":["HIMACにおける可変エネルギー運転の高度化"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:53:58.076940+00:00"}
