The synchrotron acceleration system is required to be of a wide bandwidth with the frequency sweeping from 1.64MHz to 14.26MHz, and a high gradient with the maximum acceleration voltage of 20kV. The prototype of the rf acceleration system has been developed. The rf cavity consists of 2 cells loaded with 4 high-permeability magnetic alloy cores in each cell, and a push-pull power amplifier with two 35kW tetrode tubes is used to drive the 2 cells of the cavity in parallel. The test results and design values of the rf cavity and power amplifier 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":"APAC'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":"665596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"方 志高","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"665597","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":"TEST RESULTS OF RF CAVITY AND POWER AMPLIFIER FOR COMPACT MEDICAL PROTON SYNCHROTRON","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TEST RESULTS OF RF CAVITY AND POWER AMPLIFIER FOR COMPACT MEDICAL PROTON SYNCHROTRON"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-03-31"},"publish_date":"2004-03-31","publish_status":"0","recid":"67735","relation_version_is_last":true,"title":["TEST RESULTS OF RF CAVITY AND POWER AMPLIFIER FOR COMPACT MEDICAL PROTON SYNCHROTRON"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:34:19.042539+00:00"}
