A superconducting coil conductor composed of a plurality of strands (10) twisted together to form a cylindrical structure, each strand (10) being composed of a core (2) composed of a plurality of parallel filaments of a superconducting material, enclosed by a metal sheath (4) forming a matrix in which at least some of the filaments are embedded, and a tubular member (6) enclosing the sheath (4) so as to be in intimate electrical contact with the sheath (4) and support the core (2). The conductor is held in support plates (16) each presenting a U-shaped conductor support channel (20) spaced inwardly from an exterior surface of the support plate (16) which is in contact with the cryogen, and a conductor compression wedge (18) inserted in the channel (20) for holding the conductor in place. The solenoid coil further includes insulating members (38) interposed between the support plates (16) and projecting radially beyond the conductor support system. This coil is radially supported by a plurality of rigid radial support units (46,60) spaced apart along the circumference of the coil and located between the coil and an enclosure side wall, each support unit (46,60) including a support structure (46) having a bearing surface (50) which contacts the coil and which includes support grooves (48) receiving the coil insulating members (38). For installing the support units (46,60) at room temperature, the coil is subjected to radial inward compressive forces which are retained until the support units (46,60) have been installed, the radial forces then being removed.
