1. A superconducting magnet assembly, comprising:
a cold mass comprising superconducting magnet coils within an outer vacuum chamber with a thermal radiation shield located around the cold mass and inside the outer vacuum chamber; and
a self-supporting flexible shield configured to substantially enclose the cold mass,
wherein the self-supporting flexible shield comprises a shaped plastic sheet having a low emissivity coating on both sides and being located between the cold mass and the thermal radiation shield, the shaped plastic sheet including a folded structure that is attached to the cold mass,
wherein the folded structure comprises a folded box cover.
