The advent of REBCO tape has led to the development of tape-wound coils by a number of organizations. The 32 T magnet at the NHMFL uses two coils made of double-pancakes of REBCO installed within five LTS coils. It reached full field in December 2017. This is the highest field produced by an all-superconducting magnet to date. Since the 1970s it has been known that screening currents exist in tape-wound magnets which impact field distribution, helium consumption and stress. In recent years several groups have been computing screening currents and ac losses in REBCO tape in a variety of applications. However, there has been little published about coils of this size, particularly the stress state. This problem is very challenging due to the need to analyze 20,000 REBCO turns which are not bonded together. The T-A formulation of Maxwell’s equations employing a homogenization technique enables efficient estimation of the current distribution while structural calculations employing contact element allows estimation of stresses. Computational results are compared with test results.
