FIELD : applied superconductivity.SUBSTANCE : proposed method that can be used for manufacturing mechanically loaded superconductor windings designed for sustaining conductor stress higher than 100 MPa as well as superconductor windings and devices designed for operation under variable conditions, such as superconducting magnets for charged particle accelerators and superconductor inductive energy storages involves use of liquid epoxy resin as filler doped with finely dispersed powder of rare-earth intermetallide, for instance HoCu2 (holmium-copper) or CeCu2 (cerium-copper). Filler concentration is chosen between 20 and 50% of liquid epoxy resin volume.EFFECT : enhanced performance characteristics of superconductor windings under variable conditions.4 cl, 2 dwg
