This exciting result gives new urgency for Inertial Fusion Energy (IFE) and has reinvigorated alternative ICF schemes that have the potential for the higher gains. One such scheme is fast ignition (FI). FI is a two-step process that uses nanosecond lasers to compress an ICF capsule, then uses picosecond, short-pulse (SP) lasers to accelerate particles (i.e., electrons, ions) that heat the core to fusion temperatures. This separation of stages allows for higher gain and reduced symmetry constraints.<br \/>\nTo understand the feasibility of FI, we estimate the SP laser energy required for fast ignition considering both SP-accelerated electrons and ions. This is done by evaluating the current state-of-the-art conversion efficiencies, such as laser-to-particle, transport, energy-spectra and focusing efficiencies. These values point to critical issues that must be solved for the success of FI. LLNL has recently begun a Strategic Initiative that will work to resolve these issues through dedicated experiments and simulations. We will describe the experimental work planned and supporting simulations.<\/p>\n<p>&nbsp;<\/p>\n<p>\u25cb\u9023\u7d61\u5148(Contact Person):<br \/>\n\u5ca9\u7530\u590f\u5f25<br \/>\niwata.natsumi.ile@osaka-u.ac.jp<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u7b2c656\u56de\u30ec\u30fc\u30b6\u30fc\u79d1\u5b66\u7814\u7a76\u6240\u30b3\u30ed\u30ad\u30a6\u30e0 &nbsp; \u25cf\u65e5\u6642(Date): 2024\u5e745\u670829\u65e5 13\u664200\u5206\uff5e14\u664200\u5206 &nbsp; \u25cb\u5834\u6240(Place): \u30ec\u30fc\u30b6\u30fc\u79d1\u5b66\u7814\u7a76\u6240 \u7814\u7a76\u68df4F \u5927\u30db\u30fc\u30eb \u30cf\u30a4\u30d6\u30ea\u30c3\u30c9\u958b [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_links_to":"","_links_to_target":""},"categories":[6,8],"tags":[],"_links":{"self":[{"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/posts\/11597"}],"collection":[{"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/comments?post=11597"}],"version-history":[{"count":5,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/posts\/11597\/revisions"}],"predecessor-version":[{"id":11620,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/posts\/11597\/revisions\/11620"}],"wp:attachment":[{"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/media?parent=11597"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/categories?post=11597"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www-wp22.ile.osaka-u.ac.jp\/wp-json\/wp\/v2\/tags?post=11597"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
