Abstract:

Firstly introduced in 2010 at the MIT Francis Bitter Magnet Laboratory, the “No-Insulation” winding technique has been regarded as a “game changer” in high temperature superconductor (HTS) magnet technology, as it enables an NI HTS magnet to be highly compact and affordable, yet reliable to a level that has never been achieved with conventional systems. Significant progress in the NI-HTS technology, achieved since then and continuing today, has transformed the future dream of HTS machines into reality, i.e., meet rigorous HTS system specifications that were regarded to be infeasible mainly due to old technical challenges and high cost of HTS machines. We are now at the threshold of a new era in which HTS will play an increasingly indispensable role in a number of energy applications that include electric power system, high energy physics, non-invasive diagnostics such as MRI and NMR, environmental industry, and more. The NI-HTS magnet technology is now providing fundamental and essential solutions to many engineering problems arisen in most direct-current superconducting systems. And it will do more so in future HTS applications that require better mechanical integrity, more stable operation, and optimized cost-performance design. This seminar presents an overview of superconducting magnet technology focusing on high "magnetic field" and large "electric power" systems that include: 1) Magnetic Resonance Imaging (MRI); 2) Nuclear Magnetic Resonance (NMR); 3) clinical devices; 4) particle accelerators and detectors; 5) environmental devices; 6) power cables; 7) motors and generators; 8) energy storages; and 9) military “defense” systems. Key technical challenges as well as state-of-the-art of each application will be presented and discussed in detail.
