During the density rise, the transport barrier with steep temperature and density gradients near the plasma edge has been formed. Edge localized modes ( ELM )-like activity is also observed. Incoherent magnetic fluctuations in the frequency range f > 20 kHz are clearly suppressed during the density rise phase, while low frequency coherent part remains almost unchanged. Global energy confinement time in the density rise phase is improved by ~15 %, compared with that of the discharge without the OH-current. These experimental observations are very similar to the H-mode in tokamaks. There is a threshold of the current for the transition, where the increment of rotational transform by the threshold current corresponds to ~ 0.1 at the edge. No obvious increase in the edge poloidal rotation velocity, however, is observed during the density rise phase, that is, at most ~ 3 km/s.\"","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-198"}]},"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":"\"Toi,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamura,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iguchi,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morita,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakakibara,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ida,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishimura,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuoka,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akiyama,  R.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arimoto,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujiwara,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hosokawa,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Idei,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneko,  O.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubo,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sagara,  A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi,  C.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeiri,  Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takita,  Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsumori,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada,  I.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zushi,  H.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"H-mode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transport barrier","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"heliotron/torsatron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rotational transform","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"confinement improvement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"edge localized modes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"threshold plasma current","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"edge poloidal rotation","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Formation of H-mode Like Transport Barrier in the CHS Heliotron / Torsatron","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Formation of H-mode Like Transport Barrier in the CHS Heliotron / Torsatron","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10330","relation_version_is_last":true,"title":["Formation of H-mode Like Transport Barrier in the CHS Heliotron / Torsatron"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:51:06.635093+00:00"}
