Charging an HTS Coil: Flux Pump With an HTS Square Bridge

Lin Zhi Fu, Koichi Matsuda, Boyang Shen, Tim A. Coombs

Open publisher page 10 citations

Abstract

In recent years, along with the unceasing development of High-temperature Superconductor (HTS) technology, the performance of HTS tape has been improved significantly, including the higher critical current, lower joint resistance, and longer tape length etc. To use HTS instead of Low-temperature Superconductor (LTS) in Magnetic Resonance Imaging (MRI) applications, the flux pumping method with travelling wave has been investigated. In this paper, our new experimental results were regarding to the frequency, amplitude, and wavelength characteristics of charging an HTS coil with an HTS square bridge, using an electromagnetic flux pump designed at the University of Cambridge.
