The rf cavity consists of 2 cells loaded with 4 high-permeability magnetic alloy cores in each cell, and the 2 cells of rf cavity are driven by a push-pull power amplifier in parallel which is formed with two tetrode tubes 4CX35,000C. The rf system is operated in pulse mode. During the beam acceleration time of 5 ms, the rf frequency sweeps from 2.0MHz to 17.8MHz and the cavity voltage varies from 10.0kV to 1.6kV. The high power test of the rf system is being performed, and the required gap voltage has been successfully achieved. The performance of the rf system will be 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":"EPAC'04 Organizing Committee","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":"Fan"}],"nameIdentifiers":[{"nameIdentifier":"666530","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"方 志高","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666531","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"RF SYSTEM FOR COMPACT MEDICAL PROTON SYNCHROTRON","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RF SYSTEM FOR COMPACT MEDICAL PROTON SYNCHROTRON"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-07-27"},"publish_date":"2004-07-27","publish_status":"0","recid":"67843","relation_version_is_last":true,"title":["RF SYSTEM FOR COMPACT MEDICAL PROTON SYNCHROTRON"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:33:05.678447+00:00"}
