A multi-orientation cryostat 5 for a superconducting magnet 4 for use in a plurality of orientations. The cryostat 5 comprises a vessel 6 for holding cryogenic liquid and, leading away from the vessel, a quench duct 7 for allowing escape from the vessel of gas generated by boiling of the cryogenic liquid due to quenching of the magnet. The quench duct 7 is sinuous so as to provide at least to differently orientated anti-convection portions 71, each portion for functioning as an anti-convection portion with the cryostat in a respective corresponding orientation.
