Manufacturing of the stainless-steel sheathed magnesium diboride superconductor wire [PDF]

Science of Sintering
The Powder in Tube (PIT) method was utilized to manufacture the MgB2-based monofilament wire. The ground powders of Mg and B were filled in the stainless-steel tube and went through a cold-rolling process.

rf surface impedance of a two-band superconductor

Physical Review Accelerators and Beams, 2019
In this paper, we extend the Mattis-Bardeen theory to obtain the surface impedance of a two-band superconductor, and apply it to magnesium diboride (MgB_{2}) for radiofrequency (rf) superconductivity applications. The numerical results for MgB_{2} are in
