Thermal and Electrical Stabilities of Solid Nitrogen (SN2) Cooled YBCO Coated Conductors for HTS Magnet Applications

High Temperature Superconducting (HTS) materials will be applied to magnet systems if they will satisfy engineering specifications about performances and if their costs will be "acceptable" (i.e. justified by the benefits of their usage). Although there are now more than 50 known HTS materials, only Bi-2212 and Bi-2223 are available as long-length conductors usable for prototypes of cryocooler cooled magnets, high field insert coils, transformers, etc. Conductor performances of importance in magnet systems design will be addressed like: engineering critical current, anisotropy, strain tolerance, AC losses, resistive transition and n-value. Achieved costs and performances of HTS magnet systems will be reviewed and possible future improvements will be discussed by considering also YBCO coated conductors and MgB2 wires under development.

Ybco Coated Conductors

Short segments of YBa2Cu3O7-y (YBCO) coated conductors were fabricated on rolling-assisted biaxially textured substrates (RABiTS) with a layer sequence of CeO2/YSZ/Ni using an ex situ BaF2 precursor process. Pulsed laser deposition (PLD) was used to deposit both YSZ and CeO2 layers. The YBCO films were grown using e-beam coevaporated Y–BaF2–Cu precursors followed by postannealing. An overall engineering current density, JE, of 28,000 A/cm2 and critical current, Ic, of 147 A/cm width at 77 K were achieved for a 1.6-μm-thick YBCO film. This result demonstrates the possibility of using both the ex situ BaF2 precursor approach and the RABiTS process for producing long lengths of high-JE coated conductors.
