TL;DR: In this paper, a symmetric tape round (STAR) REBCO wire was developed for the needs of compact accelerator magnets requiring round isotropic wire with an engineering current density (J e ) of 600 A mm−2 at 4.2 K, 20 T at a bend radius of 15 mm.
Journal ArticleDOI
Ultra-Small Diameter Round REBCO Wire With Robust Mechanical Properties
TL;DR: In this article, the compressive bend diameter of REBCO tape was compared after copper electroplating only on the REBO side and on both sides of the tape, and the results confirmed the superior retention of critical current under combined effect of high torsion and compressive bends.
Journal ArticleDOI

TL;DR: In this article, the authors present results on the in-field critical current (Ic) performance of 4.0 μm thick REBCO film with 15% Hf addition up to 31.2 T at field orientations B||ab plane and B||c axis.
Journal ArticleDOI
Fabrication and Electromagnetic Characterization of Ultrasmall Diameter REBCO Wires
TL;DR: Using ultrathin RE-Ba-Cu-O (REBCO, RE = rare earth) superconductor tapes, a multilayer round wire with an outer diameter of 1.6 mm on a flexible copper former of 0.8 mm diameter was fabricated.
Journal ArticleDOI
