In this paper, we propose the use of Cr-coated MgB2 wires to enhance the charging/discharging rates of the MgB2 magnet fabricated with a partial insulation (PI) winding technique that can provide a self-protecting feature to the magnet. The charging/discharging rates of the PI magnets with the Cr-coated MgB2 wires was approximately 10 times faster than that the magnets with un-coated wires. In addition, the self-protective behavior of the PI magnet with the Cr-coated wires was verified via over-current analysis. From the test results, the effectiveness of the proposed winding technique was verified for the development of self-protective MgB2 magnetic resonance imaging (MRI) magnets with rapid charging/discharging rates. |
