Abstract

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 ∼ 2.8 × 10⁴ A cm^-2). At 4 K this coil generated 1.6 T under an applied field of 1.25 T (I_c ∼ 350 A, J_e ∼ 4.5 × 10⁴ 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 > 10⁴ A cm^-2 at 7 T.
