Abstract: PURPOSE:To improve magnetic field accuracy with simple constitution and to reduce the cost of the device by helically twisting the hollow part of the prescribed shape of a superconductor member inserted into a simple toroidal coil in a torus direction, thereby penetrating this part through the coil. CONSTITUTION:The hollow part 12 of a superconducting block 11 is so constituted as to make complete one turn in an angle psi direction to arrive at the initial sectional position while twisting in a poloidal angle theta direction in the state of maintaining the sectional state with the displacement in the toroidal angle psidirection from a sectional part 13 in the front part up to a sectional part 14 in the rear part. The magnetic field generated by the toroidal coil 10 exists in the hollow part 12 but is prevented by a Meissner effect from existing in the block 11 itself; further, the perpendicular component in the magnetic field on this surface is zero. Since the hollow part 12 is thereby rotated in the angle psiand theta directions, the magnetic field component eventually has the component of the angle theta direction as well in addition to the component of the angle psidirection at the time of the coil 10 alone. The generated magnetic lines of force are eventually twisted and charge sepn. is eliminated. The effective confinement of plasma is thus executed.
