Steady-State Toroidal Plasma Thermally Self-Sustained by Thermonuclear Fusion Reaction

抄録

Without an assumption employed by Furth et al., numerical steady-state solutions of a D-T toroidal plasma are obtained in a self-consistent way from the momentum, energy and Maxwell equations for ions and electrons. The solutions satisfy the following requirements for the toroidal plasma in a power plant: 1) The ion temperature at the central part of plasma is high enough to feed a sufficient output power due to thermonuclear fusion reaction; 2) at the boundary, on the other hand, the ion temperature is so low as to keep the blanket out of thermal damages; 3) the safety factor with respect to screw instability is greater than 2 everywhere in the plasma.
