摘要: Error fields in tokamak magnet systems are primarily associated with displacements of toroidal field and poloidal coils, arising during their manufacture assembly. The Fourier analysis error on a rational magnetic flux surface, anticipated the ITER machine, exhibited lower-order modes ((m, n)=(1,1), (2,1), (3,1)) as most crucial ones. A statistical study using Monte Carlo simulations has demonstrated that an averaged three-mode from superposition coil can be two to three times higher than acceptable level. estimates obtained have been used assess capability correction system.
