Abstract

Flux diverters made of ferromagnetic materials can be used in high-temperature superconducting (HTS) magnets to change the magnetic field distribution and increase the critical current of the magnet. In this paper, the notch-shaped flux diverter increases the critical current of the HTS magnet by detouring the magnetic flux more effectively than the flat surface-shaped (simple) flux diverter. Numerical analyses are carried out to calculate the critical current using the simple-shaped and the notch-shaped flux diverters. Then, experiments are conducted to verify the results of the numerical analyses. As a result, the HTS coil with a notch-shaped flux diverter shows the increased critical current.
