A limb size MRI magnet coldmass has been constructed using DI-BSCCO tapes from Sumitomo. The coils were wound with epoxy pre-impregnated fiberglass cloth (pre-preg) between layers to bond the wires. For radial dimensional control, temperature was elevated during the winding to thin out the epoxy and...
