摘要：
We present the fabrication and test results of hot-isostatic-pressed (HIPed) powder-in-tube (PIT) MgB2 coils. The coils' properties were measured by transport and magnetization at different applied fields (H) and temperatures (T). The engineering critical current (J(e)) value is the largest reported in PIT MgB2 wires or tapes. At 25 K our champion six-layer coil was able to generate a field of 1 T at zero external field (I-c > 220 A, J(e) similar to 2.8 x 10(4) A cm(-2)). At 4 K this coil generated 1.6 T under an applied field of 1.25 T (I-c similar to 350 A, J(e) similar to 4.5 x 10(4) A cm(-2)). These magnetic fields are high enough for a superconducting transformer or magnet applications such as MRI. An SIC doped MgB2 single layer coil shows a promising improvement at high fields and exhibits J(c) > 10(4) A cm(-2) at 7 T.
