ABSTRACT:
A superconducting energy storage magnet is formed having inner (13) and outer (14) coils which are supported and restrained by an inner support structure (15) comprised of thermal and electrically conductive rails (33) which engage and parallel the turns of composite conductors (30, 31) in the two coils. Each of the support rails (33) is electrically isolated from adjacent support rails by insulating spacers (33) between layers and an insulating spacer (35) between the rails for the inner and outer coils. The spacing between turns in the inner and outer coils preferably progressively decreases toward the top and bottom ends of the magnet in a manner to best direct the magnetically induced forces on the composite conductors (30, 31) into the inner support structure. The two layer coil structure causes the forces on the conductors when current is flowing therethrough to be directed primarily inwardly toward the inner support structure (15).
