Superconducting Joining Method between REBCO Coated Conductors

Scientific Report Transverse Thermal Conductivity of REBCO Coated Conductors

REBCO coated conductors (CCs) have the potential to widen considerably the application areas of superconductivity. Quench protection of REBCO-based devices represents one of the major obstacles to this expansion. Thermal conductivity data are mandatory ingredients for quench simulation studies. In particular, the transverse thermal conductivity (kT) of the CC plays a key role in case of quenche...

Field and temperature scaling of the critical current density in commercial REBCO coated conductors

Scaling relations describing the electromagnetic behaviour of coated conductors (CCs) greatly simplify the design of REBCO-based devices. The performance of REBCO CCs is strongly influenced by fabrication route, conductor architecture and materials, and these parameters vary from one manufacturer to the others. In the present work we have examined the critical surface for the current density, J...

Influence of neutron irradiation on high temperature superconducting coated conductors

High temperature superconductors (HTS) might be applied for the magnets in a next step fusion device. The magnets could operate in the temperature range of liquid nitrogen or slightly below. Apart from the special requirements on the mechanical properties, the conductors will be exposed to radiation. We examine the influence of neutron irradiation on coated conductors. These conductors were irr...

An equation for the quench propagation velocity valid for high field magnet use of REBCO coated conductors

Based on a study of the thermophysical properties, we derived a practical formula for the normal zone propagation velocity appropriate for REBa2Cu3O7-x coated conductors in high magnetic fields. An analytical expression to evaluate the current sharing temperature as a function of the operating conditions is also proposed. The presented study has allowed us to account for experimental results no...
