Title (EN) TOKAMAK WITH POLOIDAL FIELD COIL ARRANGEMENT FOR DOUBLE NULL MERGING IGNITION, METHOD THEREFOR AND NUCLEAR FUSUION REACTOR WITH THE SAME.
(FR) TOKAMAK À AGENCEMENT DE BOBINES À CHAMP POLOÏDAL PERMETTANT UN ALLUMAGE À DOUBLE FUSION NULLE, PROCÉDÉ ASSOCIÉ ET RÉACTEUR À NUCLÉAIRE ÉQUIPÉ DUDIT TOKAMAK
Abstract:
(EN) A tokamak comprising a toroidal containment vessel and a plasma initiation system. The toroidal containment vessel is configured to contain a plasma. The plasma initiation system comprises upper and lower poloidal field, PF, coil sets. Each PF coil set comprises at least one inner PF coil located outside of the containment vessel, an outer PF coil located inside the containment vessel, and shielding located between the outer PF coil and a location of the plasma during operation of the tokamak and configured to protect the outer PF coil from heat emitted by the plasma. The inner and outer PF coils are configured so as to form a PF null within the containment vessel between the inner and outer PF coils, such that the upper and lower PF coil pairs are operable to initiate a plasma in the containment vessel via double null merging.
(FR) La présente invention concerne un tokamak comprenant une enveloppe de confinement toroïdale et un système d'amorçage de plasma. L'enveloppe de confinement toroïdale est conçue de façon à contenir un plasma. Le système d'amorçage de plasma comprend des ensembles bobines à champ poloïdal (PF) supérieur et inférieur. Chaque ensemble bobine PF comprend au moins une bobine PF interne située à l'extérieur de l'enveloppe de confinement, une bobine PF externe située à l'intérieur de l'enveloppe de confinement, et un blindage qui est situé entre la bobine PF externe et un emplacement du plasma pendant le fonctionnement du tokamak et qui est configuré de façon à protéger la bobine PF externe de la chaleur émise par le plasma. Les bobines PF interne et externe sont configurées de façon à former un PF nul dans l'enveloppe de confinement entre les bobines PF interne et externe, de telle sorte que les paires de bobines PF supérieure et inférieure permettent d'amorcer un plasma dans l'enveloppe de confinement par l'intermédiaire d'une double fusion nulle.
