Strategies for conformal REBCO windings

Abstract

A high-field winding can be fabricated from a cable of non-insulated REBCO tapes, stacked face-face without twisting. If the cable is oriented within each turn of a winding so that the tape face is closely parallel to the magnetic field at its location, the supercurrent capacity of that cable is enhanced ~3x greater than in a transverse or twisting orientation. This concept for a conformal winding was presented in a previous paper pertinent to the body winding of a high-field dipole. Strategies are presented and simulated for how the same orientation can be sustained in the flared ends of a dipole.
