On the TST-2 spherical tokamak, non-inductive plasma start-up using lower-hybrid (LH) waves has been investigated. Using the capacitively-coupled combline (CCC) antenna installed at the outboard midplane, fully non-inductive plasma current ramp-up up to a quarter of that of the typical Ohmic discharges has been achieved. Although it was desirable to keep the density low during the plasma current ramp-up to avoid the LH density limit, it was recognized that there was a maximum current density that could be carried by a given electron density. Since the density needed to increase as the plasma current was ramped-up, the achievable plasma current was limited by the maximum operational toroidal field of TST-2. The top-launch CCC antenna was installed to access higher density with up-shift of the parallel index of refraction. Numerical analysis of LH current drive with the outboard-launch and top-launch antennas was performed and the results were qualitatively consistent with the experimental observations.","subitem_description_type":"Abstract"}]},"item_10003_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1051/epjconf/201715702009","subitem_relation_type_select":"DOI"}}]},"item_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.epj-conferences.org/articles/epjconf/abs/2017/26/epjconf_rfppc2017_02009/epjconf_rfppc2017_02009.html"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.epj-conferences.org/articles/epjconf/abs/2017/26/epjconf_rfppc2017_02009/epjconf_rfppc2017_02009.html","subitem_relation_type_select":"URI"}}]},"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":"Tsujii, Naoto"}],"nameIdentifiers":[{"nameIdentifier":"561077","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takase, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"561078","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ejiri, Akira"}],"nameIdentifiers":[{"nameIdentifier":"561079","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新屋, 貴浩"}],"nameIdentifiers":[{"nameIdentifier":"561080","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yajima, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"561081","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamazaki, Hibiki"}],"nameIdentifiers":[{"nameIdentifier":"561082","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Togashi, Hiro"}],"nameIdentifiers":[{"nameIdentifier":"561083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"P., Moeller Charles"}],"nameIdentifiers":[{"nameIdentifier":"561084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Roidl, Benedikt"}],"nameIdentifiers":[{"nameIdentifier":"561085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"561086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toida, Kazuya"}],"nameIdentifiers":[{"nameIdentifier":"561087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Yusuke"}],"nameIdentifiers":[{"nameIdentifier":"561088","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新屋 貴浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561089","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Fully non-inductive plasma start-up with lower-hybrid waves using the outboard-launch and top-launch antennas on the TST-2 spherical tokamak","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fully non-inductive plasma start-up with lower-hybrid waves using the outboard-launch and top-launch antennas on the TST-2 spherical tokamak"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-14"},"publish_date":"2018-03-14","publish_status":"0","recid":"54867","relation_version_is_last":true,"title":["Fully non-inductive plasma start-up with lower-hybrid waves using the outboard-launch and top-launch antennas on the TST-2 spherical tokamak"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:55:52.463646+00:00"}
