REBCO conductors are emerging as a prominent choice among high-temperature superconductors due to their superior superconducting properties at high magnetic fields. However, depending on the fabrication route, there can be microstructural heterogeneities such as porosity, CuO precipitates, and a-axis grains. Such defects at a larger scale can disrupt current transport and limit the critical...

The development of new high-field superconducting magnets is significantly constrained by the limiting critical properties of superconducting coated conductors (CCs). A major challenge is that REBCO tapes have high critical current densities. It is essential to create micro-bridges on REBCO tapes to test the critical current at low temperatures and high fields. However, pulsed high magnetic...

NHMFL is designing a 40 T superconducting user magnet [1]. In this magnet, significant quantity of REBCO coated conductor will be used for the insert coils. Fully characterizing critical current (Ic) of REBCO tapes at temperatures of its operation (4.2 K) and during a potential magnet quench (> 4.2 K) is critical to the success of the project. Due to the strong anisotropy of REBCO coated...

By using TELENE® resin as superconducting magnet impregnation material, training and magnet retraining after a thermal cycle were nearly eliminated in Nb3Sn undulators and NbTi accelerator magnets. We herein perform a study on how effective TELENE is in preventing quenches also in HTS magnets, without damaging the superconductor. This study encompasses measurements of transport current,...

A 5 T high-temperature superconducting (HTS) magnet utilizing conduction cooling with REBCO tape has been designed and constructed at the Wuhan National High Magnetic Field Center (WHMFC). The magnet comprises three double pancake (DP) coils, employing a no-insulation (NI) winding technique，and is designed to operate at a current of 260 A at 4 K. During magnet operation, the turn-to-turn...

The critical properties of REBa2Cu3O7-x (REBCO, RE = Rare Earth) tapes are essential for applications in high-field magnets. Typically, the critical current (Ic) of REBCO tapes is measured under steady-state magnetic fields using direct current (DC). However, at low temperatures, the Ic of these tapes can reach 4 kA, posing significant...
