ABSTRACT:
A superconductor device which including a magnet coil assembly and support structures. The magnet coil assembly consists of superconducting wire which is encased in a composite structure along with an integral thermal interface. This combination forms the magnet coil assembly. The magnet coil assembly is cooled to an operating temperature of about 5K with a conductive cooling device that physically connects with the thermal interface integral to the magnet coil assembly. A cold-to-warm support structure supports the magnet coil assembly within a vacuum vessel while thermally isolating it from the external environment Structurally, the magnet coil assembly is cylindrically shaped and positioned within a toriodal shaped thermal shield which is positioned within a toroidal shaped vacuum vessel. The cold-to-warm support structure supports the magnet coil assembly spaced apart from the thermal shield. The cold-to-warm support structure includes a tapered section and an annular section. The tapered section is shaped as a truncated cone and is attached to a proximal end of the vacuum vessel. The tapered cone extends distally and projects radially into the vacuum chamber. The tapered cone passes through an interface in the thermal shield and is connected to a second end of the annular section. The annular section extends proximally from the tapered section and includes a first end that is connected to the magnet coil assembly.
