Monofilament MgB₂ wires for MRI magnets
MRI magnets are useful medical devices in early detection and efficient treatment of disease or injury. Because of the significant better performance, MRI magnets are made of superconductors rather than made of copper. Nowadays, there are over 20,000 superconducting MRI magnets installed worldwide. …

A persistent-mode MgB₂ 0.5-T/240-mm solid-nitrogen-cooled magnet for MRI
Magnetic resonance imaging (MRI) has become one of the major noninvasive diagnostic imaging tools today. The annual $5-billion market drives magnet engineers to develop advanced and innovative, high-quality, low-cost, easy-to-operate MRI magnets. Because superconductors carry more than 100 times …

Increased critical current density in rapidly grown RE-based cuprate superconducting coated conductors
… new and improved devices, with applications from MRI magnets to fusion power plants. However, to be successfully commercialised the cost of performance of the wires must be improved. This thesis investigates a new method of producing high quality REBa2Cu3O7-x films at fast rates which could help …

An investigation into high temperature superconducting flux pump technology with the circular type magnetic flux pump devices and YBaCuO films
… applications such as magnetic resonance imaging (MRI) magnets, electrical machines, magnetic levitation trains, energy storage, etc. 2G HTS coils can be operated using either dc current or ac current. Several important issues have yet to be resolved, such as how to properly magnetise an HTS coil …
