Scoping studies of a high-field ITER device have been performed. Possible advantages of high field operation include: reduced machine size and cost, decreased fusion power and tritium consumption, lower current, and higher density operation (which may increase the design window for the divertor targets). The use of high aspect ratio minimizes the need for increased field at the superconductor by increasing the ratio between the field at the plasma and the peak field at the coil. Higher aspect ratio also results in stresses in the magnet structure that are within present ITER design limits. The current densities in the conductors are consistent with the use of Nb3Sn. The impact of high field on steady-state current drive is evaluated.
