In this study, the heating characteristics of the second-harmonic ordinary (O2) and third-harmonic extraordinary (X3) modes and the possible extension of heating regime are experimentally confirmed. At the same time, a comparative study using ray-tracing calculation was performed in the realistic three-dimensional configuration of the Large Helical Device. The O2 mode heating showed a 40% absorption rate even above the X2 mode cut-off density. The X3 mode heating using powerful 77 GHz gyrotrons demonstrated an increase of about 40% in the central electron temperature in the plasmas at β-value of about 1%. These results were quantitatively explained to some extent by ray-tracing calculations.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"プラズマ・核融合学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.8.2402073","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2013 The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SHIMOZUMA,  Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASHI,  Hiromi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUBO,  Shin","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIMURA,  Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IGAMI,  Hiroe","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHIURA,  Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGASAWARA,  Shinya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MAKINO,  Ryohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IDEI,  Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MARUSHCHENKO,  Nikolai B","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TURKIN,  Yuri","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUTOH,  Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-23"}],"displaytype":"detail","filename":"pfr2013_08-2402073.pdf","filesize":[{"value":"6.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2013_08-2402073.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/330/files/pfr2013_08-2402073.pdf"},"version_id":"567d54ca-34a1-4e4b-bd4a-ede557b94ae5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electron cyclotron heating","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ECH","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"high harmonic heating","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gyrotron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"absorption rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ray-tracing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LHD","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High Harmonic ECH Experiment for Extension of Heating Parameter Regime in LHD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High Harmonic ECH Experiment for Extension of Heating Parameter Regime in LHD","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-10-21"},"publish_date":"2013-10-21","publish_status":"0","recid":"330","relation_version_is_last":true,"title":["High Harmonic ECH Experiment for Extension of Heating Parameter Regime in LHD"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T16:43:55.457497+00:00"}
