Abstract

This study investigates the feasibility of using the partial insulation winding technique for the development of a self-protective MgB₂ MRI magnet with a fast charge-discharge rate. Charge-discharge and quench tests for a prototype PI MgB₂ magnet confirmed that the magnet was successfully operated at full-field performance and exhibited self-protecting behavior in the event of a quench. Nonetheless, the required time to charge the 0.5-T/300-mm PI MgB₂ magnet was almost five days, implying that the charge-discharge delay of the PI MgB₂ magnet still needs to be ameliorated further to develop a real-scale MgB₂ MRI magnet with a fast charge-discharge rate.
