The use of superconductors in an RFP reactor, although mandatory in the magnetizing\/equilibrium coils, could represent an issue due to their limitations in the allowed magnetic field derivative, which is quite high during the initial plasma current phase of the RFP operation. A new concept is proposed based on a double-coil system: the first made with superconductors and the other with conventional copper coils. The basic principle is first introduced with the help of a simplified model that allows understanding the double-coil system operation. A feasibility study applying this solution has been carried out in the design of the poloidal magnetic system of a pilot RFP (R = 4 m and a = 0.8 m) as a fusion core for an FFHR. This article presents the preliminary results and, in particular, the possibility of obtaining high initial loop voltage for a fast rise of the RFP plasma current with a magnetic field derivative within the superconductor limits.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Piovan R.; Agostinetti P.; Bustreo C.; Cavazzana R.; Escande D.F.; Gaio E.; Lunardon F.; Maistrello A.; Marrelli L.; Puiatti M.E.; Valisa M.; Zollino G.; Zuin M.<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[574],"product_tag":[1481,1528,1529,1531],"class_list":["post-8842","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-journal-articles","product_tag-superconducting-magnets","product_tag-fusion-reactors","product_tag-hybrid-nuclear-power-systems","product_tag-reversed-field-pinch-rfp","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/8842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=8842"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=8842"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=8842"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=8842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
