摘要: A ring of accurately placed and matched printed circuit coils is at the center DIII‐D tokamak vacuum vessel, aligned magnetically with toroidal field used to measure nonaxisymmetric magnetic each 18 poloidal coils. [Toroidal variations can be mode n m, respectively, helical form cos(nφ−mθ).] From error fields, it computed that most irregular coil one outer vertical having a shift 1.9 ±0.2 cm (compared diameter 482 cm), an ellipticity 1.0027. All together make resonant, helical, radial for m=2, n=1 about 1.4 × 10−4 field.
