The aim of this prototype accelerator is to demonstrate the validity of the low energy section of an IFMIF deuteron accelerator up to 9 MeV with a beam current of 125 mA in continuous wave (CW). The high power conditioning and the beam commissioning have been conducted since July 2017 on the world longest and highest power Radio Frequency Quadrupole (RFQ) linear accelerator. This RFQ requires 1.6 MW of RF power, and we have faced several problems on the cooling and electrical system specific to such a very high power accelerator. In this presentation, we will describe lessons we have learned over the past two years of operation in particular for maintenances and how an improvement is implemented to achieve stable operation.","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":"The 7th Accelerator Reliability Workshop (ARW 2019)","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":"Kondo, Keitaro"}],"nameIdentifiers":[{"nameIdentifier":"843298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ihara, Akira"}],"nameIdentifiers":[{"nameIdentifier":"843299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikeda, Yukiharu"}],"nameIdentifiers":[{"nameIdentifier":"843300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"843301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugimoto, Masayoshi"}],"nameIdentifiers":[{"nameIdentifier":"843302","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeishi, Saya"}],"nameIdentifiers":[{"nameIdentifier":"843303","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Keitaro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843304","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ihara, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843305","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikeda, Yukiharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843306","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Keishi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugimoto, Masayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeishi, Saya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"843309","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":"Maintenance and enhancement of the electrical and cooling systems for the operation of Linear IFMIF Prototype Accelerator (LIPAc)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Maintenance and enhancement of the electrical and cooling systems for the operation of Linear IFMIF Prototype Accelerator (LIPAc)"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-12-10"},"publish_date":"2019-12-10","publish_status":"0","recid":"77883","relation_version_is_last":true,"title":["Maintenance and enhancement of the electrical and cooling systems for the operation of Linear IFMIF Prototype Accelerator (LIPAc)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:41:31.819693+00:00"}
