Wenzel et al 2024 Nucl. Fusion 64 034002). These values are very surprising, as generally only low pressures are predicted for stellarators. In the presentation, the results are compared with those of W7-AS. This allows the conclusion that in both cases a thermal instability of the electron temperature in the divertor occurs. Based on this, proposals for new experiments at LHD are made.<br><\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\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 decoding=\"async\" src=\"https:\/\/unit.nifs.ac.jp\/research\/wp-content\/uploads\/2024\/03\/email.jpg\" alt=\"\" class=\"wp-image-6284\" style=\"width:239px\" width=\"239\" 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=\"(max-width: 766px) 100vw, 766px\" \/><\/figure>\n","protected":false},"author":6,"featured_media":2070,"menu_order":0,"template":"","meta":{"_acf_changed":false,"footnotes":""},"ppma_author":[344],"class_list":["post-6271","news","type-news","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/6271","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":18,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/6271\/revisions"}],"predecessor-version":[{"id":6297,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/news\/6271\/revisions\/6297"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media\/2070"}],"wp:attachment":[{"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/media?parent=6271"}],"wp:term":[{"taxonomy":"author","embeddable":true,"href":"https:\/\/unit.nifs.ac.jp\/research\/wp-json\/wp\/v2\/ppma_author?post=6271"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
