Solid cryogen: a cooling system for future MgB₂ MRI magnet.

ABSTRACT: An efficient cooling system and the superconducting magnet are essential components of magnetic resonance imaging (MRI) technology. Herein, we report a solid nitrogen (SN₂) cooling system as a valuable cryogenic feature, which is targeted for easy usability and stable operation under unreliable power source conditions, in conjunction with a magnesium diboride (MgB₂) superconducting magnet. The rationally designed MgB₂/SN₂ cooling system was first considered by conducting a finite element analysis simulation, and then a demonstrator coil was empirically tested under the same conditions. In the SN₂ cooling system design, a wide temperature distribution on the SN₂ chamber was observed due to the low thermal conductivity of the
