An electromagnet (100) for a Magnetic Resonance Imaging (MRI) apparatus. The electromagnet (100) comprises a coil (110) for generating a magnetic field. The coil (110) has a first axially outer surface (112), and a support element (120) for mounting the coil (110) in the MRI. The support element (120) is bonded to t...

A self-supporting flexible shield for location between a warm surface (16) and a cold mass (10, 12) so as to substantially enclose the cold mass, wherein the self-supporting flexible shield comprises a shaped plastic sheet with a low emissivity coating on both of its sides.

An anomaly detection system comprising a diagnostic interface (10) and a data acquisition system (11) capable of recording data indicating variation of voltages at tapping points (20) in a superconducting magnet. Data representing those variations in voltages may be stored as a data log and a processor may analyse t...
