Such an enhanced phase exhibits energy confinement well beyond stellarator ISS04 scaling expectations and plasma beta values significantly above Sudo predictions. These discharges are characterized also by a peaked density profile, more negative Er&#8217;s from the edge region to the core, and increased post-injection ion temperatures, the latter being attributed to reduced ion heat diffusivity and improved ion energy confinement. In addition, reduced density and plasma potential fluctuations are seen together with high Er shear in the density gradient region, indicating the significant role of turbulence, as indicated also by numerical simulations. The injection of additional pellets has permitted record values of these parameters to be achieved in TJ-II.<br><\/p>\n\n\n<div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<p><strong>\u554f\u3044\u5408\u308f\u305b<\/strong>\uff1a\u3000\u30d7\u30e9\u30ba\u30de\u30fb\u8907\u76f8\u9593\u8f38\u9001\u30e6\u30cb\u30c3\u30c8\u3000\u672c\u5cf6<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"766\" height=\"116\" src=\"http:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email.jpg\" alt=\"\" class=\"wp-image-6284\" style=\"aspect-ratio:6.603448275862069;width:218px;height:auto\" srcset=\"https:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email.jpg 766w, https:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email-300x45.jpg 300w, https:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email-180x27.jpg 180w, https:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email-500x76.jpg 500w\" sizes=\"auto, (max-width: 766px) 100vw, 766px\" \/><\/figure>\n","protected":false},"author":6,"featured_media":2695,"menu_order":0,"template":"","meta":{"_acf_changed":false,"footnotes":""},"ppma_author":[344],"class_list":["post-7760","news","type-news","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/7760","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/users\/6"}],"version-history":[{"count":9,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/7760\/revisions"}],"predecessor-version":[{"id":7773,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/7760\/revisions\/7773"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media\/2695"}],"wp:attachment":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media?parent=7760"}],"wp:term":[{"taxonomy":"author","embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/ppma_author?post=7760"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
