MgB2 round wire is a promising material for future fusion Cable in Conduit Conductor applied in low magnetic field, due to its larger T-margin compare with NbTi. It's a competitive candidate for feeders, poloidal field or correction coils. Since MgB2 is sensitive to strain, a short twist pitch cable pattern will be taken into consideration. During cabling and conductor manufacturing, the compression on the strand is inevitable, for a cable with short twist pitch can make more severe indentation on the strands. Previous studies have shown that indentation can caused degradation of the critical current of Nb3Sn and Bi-2212 round wires. So the same research is performed on MgB2 round wire, in this paper, the critical current of artificially indented samples is measured, and the results are compared with artificially indented Nb3Sn, NbTi and Bi-2212 round wires.
- Artificial indentation
- Critical current
- MgB2 round wire
FingerprintDive into the research topics of 'Impact of Indentation on the Performance of MgB<sub>2</sub> Round Wire'. Together they form a unique fingerprint.
