A cryostat comprises a cryogen vessel suspended within an outer vacuum container, the cryogen vessel is supported by an arrangement that includes at least one housing mounted on an exterior surface of the outer vacuum container and arranged to function as a floor mounting foot, for supporting weight of the cryogen vessel and the outer vacuum container, and at least two mounting points mounted within the housing(s). Each of at least two suspension elements (an upper suspension element and a lower suspension element) extends through a hole in the surface of the outer vacuum container, between the respective mounting point and a respective point on the cryogen vessel.
