Abstract

PURPOSE: To enhance confinement performance of a plasma without spoiling reliability of a coil and without disturbing interference with other structures by a method wherein a lead rewound wire which is parallel to a lead part and where an electric current flows in a reverse direction is installed and two or more lead crossover lines which are parallel to a between-turns crossover part and where the electric current flows in the reverse direction are installed at least at one side out of the upper and lower parts of the crossover part.
CONSTITUTION: If a lead part 2 is extracted to the upper part of a coil, a mismatch electric current region A is caused by a betweenturns crossover part 3 at the outermost circumference; therefore, a lead crossover wire 4 from a lead part 2b to a lead part 2c is arranged at the inside-diameter side so as to surround the between-turns part so that a mismatch magnetic field can be reduced. On the other hand, if the lead part 2 is arranged in a circumferential direction at an outermost circumference of the coil and is extracted to the upper part, a mismatch electric current region B due to the lead part 2 is caused; therefore, an electric current flows in a direction reverse to that of the lead part between a part from a lead part 2d to an outer feeder 5b. If a lead rewound wire 6 is arranged at an outer circumference of the lead part 2 so as to surround the lead part 2, the mismatch magnetic field is reduced.
