Abstract

A superconducting magnet structure comprising a number of axially aligned superconducting inner magnet coils (34) making up an inner magnet structure (30) and a number of superconducting outer coils (32) each having an inner diameter greater than an outer diameter of each of the inner magnet coils (34). The inner magnet structure is enclosed within a cryogen vessel (12), and the outer coils are located outside of the cryogen vessel, in thermal contact with a cooling arrangement (36, 38) for cooling the outer coils.
