<p>We describe a superconducting magnet system for generating a uniform magnetic field. The system has at least three magnets in two sets, a first of the sets comprising an oppositely disposed pair of superconducting magnets, a second of the sets comprising at least one further magnet. The further magnet is disposed such that there exists a 3D region in which a magnet field produced by the further magnet is substantially parallel to a magnetic field produced by the pair of superconducting magnets. One of the sets of magnets is configured to produce first, bulk component of the magnetic field in the 3D region and a second of the sets of magnets is configured to produce a correction to the bulk component of the magnetic field in the 3D region to reduce a non-uniformity of the bulk component of the magnetic field in the 3D region.</p> |
