The aim of this project is to develop a whole-body magnetic resonance imaging magnet that is a prototype for low-cost, easy-to-operate, and immune-from-unreliable-power-source commercial units for small hospitals, rural communities, and under-developed countries. The project will seek to develop a solid-nitrogen cooled MgB2 magnet under persistent-mode operation including three design concepts: helium-free operation; the use of high-temperature superconductors to enhance quench-free operation; and a large thermal mass in the magnet chamber to enable the magnet to maintain its operating field intact in the event of failure of the primary cooling source.
