Shape of a tokamak
WebbThe COMPASS tokamak is one of the smallest tokamaks able to operate in H-mode, with a major radius 0.6 m and height of approximately 0.7 m. Due to its size and shape, the COMPASS plasmas correspond to one tenth (in the linear scale) of the ITER plasmas. Webbinductive discharges, that is tokamaks with no toroidal electric field [24–28]. Since in most cases the effects of the Ware pinch and of the particle source, produced by both wall neutrals and neutral beam injection (NBI), have a limited impact on the shape of the density profile, the density profile is determined mainly by the balance between

WebbTokamaks are by far the leading magnetic confinement devices for controlled fusion. The progress in the past decade has demonstrated the scientific feasibility of fusion power, reaching reactor-like plasma conditions. At present, the leading facilities are the JET tokamak at Culham in the U.K. and JT-60 U at Naka in Japan. Webbför 2 dagar sedan · Providing energy from fusion and finding ways to scale up the fusion process to commercial proportions in an efficient, economical, and environmentally benign way is one of the grand challenges for engineering.
