A new approach to MgB₂superconducting magnet fabrication

Abstract

Abstract. Fabrication of MgB 2 -based superconducting magnets has been attempted by a new approach using film coated on symmetric tubes. Superconducting MgB 2 films have been prepared on iron substrates by electroplating in molten electrolytes. The critical current (I c ) of the MgB 2 electroplating films at 4.2 K and at self-field was 15 A on the basis of 1 μV/cm of I c criterion. A model calculation has shown that MgB 2 -based superconducting magnets based on MgB 2 electroplating films have the potential to generate magnetic fields over 0.5 T.

“…Single-layer coils of varying diameters are then stacked concentrically, forming a superconducting magnet. Thus far, the fabrication of YBCO coils [6] and MgB 2 coils by electroplating [7] has been attempted using this method.…”
