Beschreibung
Zusammenfassung:	A superconducting magnet comprises a liquid helium reservoir (14), superconducting magnet windings (12) disposed in the liquid helium reservoir, vacuum jacket walls (20, 22, 26) containing a vacuum volume (24) surrounding the liquid helium reservoir, and a thermal shield (30) disposed in the vacuum volume and surrounding the liquid helium reservoir. A thermal bus (50) is secured to the thermal shield. The thermal bus includes an integral heat exchanger comprising a fluid passage (60) passing through the thermal bus. An inlet fluid conduit (62) connects the liquid helium reservoir with an inlet of the fluid passage, and an outlet fluid conduit (64) connects an outlet of the fluid passage with ambient air. The thermal bus (50) is connected to the first stage cold station of a cold head (40) by a thermally conductive connection (46).
