This patent describes an installation disposed below ground level in a trench provided with a concrete lining defining a horizontal floor, the installation including a superconducting solenoid coil in the form of an annulus having a vertical axis, a first vessel having an annular form and enclosing the coil for containing a primary cryogen at a temperature sufficient to maintain the coil superconductive, and at least one second vessel having an annular form and enclosing the first vessel for containing a secondary cryogen at a selected temperature. The improvement comprises cryogen storage means spaced horizontally form the coil and the vessels for receiving the cryogens contained in the vessels; conduit means coupled between the vessels and the storage means for permitting the flow of cryogens therebetween; structural support means supporting the coil and the vessels directly from the lining floor; a source of primary cryogen in gaseous form, and piping means connected between the source and the first vessel for controllably supplying the primary cryogen in gaseous form from the source to the interior of the first vessel; and heater means disposed in the vicinity of the upper and the second vessel for heating the secondary cryogen to place the secondary cryogen in a gaseous state.
