Title: Quench protection for a layer wound HTS coil - invention, demonstration and application study –
Host: Magnets & Materials Seminar
Abstract: A layer wound HTS coil is suitable for a persistent current mode application although a pancake wound HTS coil is mainstream for developing HTS magnet applications. I have been consistently engaged in developing a layer wound HTS coil technology for application to high magnetic field NMR, especially quench protection, and I have invented a new winding method called an intra-Layer No-Insulation (LNI) method. This presentation will introduce experimental and simulation results of the 31.4 T quench test, as a demonstration of the LNI method, and simulation results of a quench behavior of the LNI coil in a 1.3 GHz LTS/HTS NMR magnet, as an application study.
