A superconducting magnet assembly is cooled. A coil former is surrounded by a heat shield, the heat shield is disposed in a vacuum reservoir, superconducting magnets are positioned around the coil former, and a refrigerant reservoir is provided. Providing two two-phase heat transfer devices 80B, 80A each having a second vacuum reservoir 62 therein and a piping system each having a vaporizer region 84 and a condenser region 86; The vaporizer region 84 is thermally connected to the coil former 30, the vaporizer region 84 of the two-phase heat transfer device 80A of the superconducting magnets 32 and 34 is thermally connected to the heat shield 26, and the refrigerant reservoir 74 And the cryocooler 70 is thermally connected to the condensation region 86 of both heat transfer devices 80A, 80B.
