The application of small cryocoolers for cooling a superconducting magnet at 12 K has important advantages especially for small and medium sized magnets. A simple construction and a helium free magnet system is obtained. The demonstration magnet developed is a six coil system with a volume of 75 L and can be regarded as a 1:3 scale MRI magnet. With a current of 100 A, a 1 T central field is generated with a maximum of 1.9 T in the windings. The magnet consists of six coil formers and five aluminum spacing rings, providing easy service and disassembly. The superconductor, a 0.6 mm diameter Nb{sub 3}Sn wire, is wound on the thin walled stainless steel coil formers after which the coil is heat treated and vacuum impregnated. Afterwards, the coil system is assembled and the electrical and thermal connections are made. This paper describes the development of the superconducting magnet.
