Superconducting joints for MRI magnet in persistent mode

Project opportunity

This Earmarked Scholarship project is aligned with a recently awarded Category 1 research grant. It offers you the opportunity to work with leading researchers and contribute to large projects of national significance.

A PhD scholarship is available to develop superconducting technologies of reacted multifilament magnesium diboride (MgB2) conductors for liquid helium (LHe)-free MRI magnet application. Over the last three decades, magnetic resonance imaging (MRI) has become an unprecedented and irreplaceable tool for diagnosis, treatment planning and monitoring. The ever-increasing insight afforded by MRI lies in continuous developments in advanced manufacturing, including those involving superconductor technology. The requirement to use a superconducting magnet cooled in LHe to produce a strong and uniform magnetic field, in the Tesla range, means that MRI is costly to manufacture and maintain, limiting its availability in remote diagnostic centres. The requirement of a bath filled with expensive LHe to cool the niobium-titanium superconducting magnet, the fabric of modern-day MRI magnets, is a major cost driver of today’s MRI instruments. Hence, the development of mainstream LHe-free MRI systems is critical to make it more widely available through a reduction in up-front and maintenance costs. The MgB2 conductor, which has a critical temperature of 39 K is known to be the most attractive candidate for this purpose.

This project aims to develop a superconducting joining technology for reacted multifilament MgB2 conductors, design a persistent-current-switch (PCS) using the multifilament MgB2 conductor and implement newly developed superconducting joints and PCS in a laboratory-scale prototype MRI magnet and operate the magnet in the persistent-mode to demonstrate its suitability for commercial MRI applications.
