Abstract

A substantially cylindrical cryostat defining an axial imaging region, the cryostat housing a magnet which, in use, provides a substantially homogeneous magnetic field in the imaging region, further comprising a refrigerator arranged to cool certain elements of the cryostat, said refrigerator comprising a magnetic material which in use, oscillates along an axis of the refrigerator. The cryostat is arranged such that the axis of the refrigerator is substantially tangential to a circle centered on the axis of the cylindrical cryostat.
