In the quench protection, accurate detection of quench occurrence in superconducting magnets is essential. There are two types of the quench detection method which is used in the magnets for the fusion devices. One is quench detection based on the balanced voltage between either two coil windings or two segments into which one coil winding is divided. The other method is quench detection by using a pickup coil whose configuration is either a disk-shaped coil or a co-wound coil. In this method, the balanced voltage between a superconducting coil and a pickup coil is utilized to detect a quench. In this study, these two methods of quench detection are investigated experimentally by using a multi-stacked (MS) pancake coil wound with Nb3Sn cable-in-conduit (CIC) conductors, which is the JT-60SA CS1 module. The experiment with the MS pancake coil was carried out in the coil test facility at the National Institute for Fusion Science, as illustrated in Fig.1. This paper describes the measurements of the balanced voltage for the MS pancake coil by the two quench detection methods. And the quench detection methods are discussed based on the measurement results.","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 10th Asian Conference on Applied Superconductivity and Cryogenics (ACASC)","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":"Obana, Tetsuhiro"}],"nameIdentifiers":[{"nameIdentifier":"820182","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahata, Kazuya"}],"nameIdentifiers":[{"nameIdentifier":"820183","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murakami, Haruyuki"}],"nameIdentifiers":[{"nameIdentifier":"820184","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murakami, Haruyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"820185","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":"Study on quench detection for a multi-stacked pancake coil wound with Nb3Sn cable-in-conduit conductors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on quench detection for a multi-stacked pancake coil wound with Nb3Sn cable-in-conduit conductors"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-01-06"},"publish_date":"2020-01-06","publish_status":"0","recid":"78335","relation_version_is_last":true,"title":["Study on quench detection for a multi-stacked pancake coil wound with Nb3Sn cable-in-conduit conductors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:20.130984+00:00"}
