Abstract
A suspension device mounts a superconducting magnet heat shield enclosure that encompasses a low-temperature container, that encompasses a superconducting magnet and holds coolant for cooling the superconducting magnet. The low-temperature container has an outer heat shield layer and an inner heat shield layer. A vacuum jacket encompasses the heat shield enclosure and has an outer vacuum shell and an inner vacuum shell. A first set of suspension parts connects the outer vacuum shell with the low-temperature container, and a second set of suspension parts connects the outer heat shield shell with the low-temperature container. Since the second set of suspension parts connect the heat shield enclosure directly with the low-temperature container, this reduces the relative movement between the two parts, thus alleviating the streaking phenomenon in a magnetic resonance image, if the superconducting magnet is part of a magnetic resonance imaging system.
