“…A pulsed ultraviolet laser, typically an excimer laser from KrF or XeCl, irradiated a sintered target with the desired composition to form a superconducting layer. The ablation of RE123 bulk material requires a laser fluence of 10-30 mJ mm −2 [29,30]: the target material is vaporized in a plasma plume and deposited on the substrate.…”

Recent progresses in the second generation REBa 2 Cu 3 O 7 − x (RE123) coated conductor (CC) have paved a way for the development of superconducting solenoids capable of generating fields well above 23.5 T, i.e. the limit of NbTi−Nb 3 Sn-based magnets. However, the RE123 magnet still poses several fundamental and engineering challenges. In this work we review the state-ofthe-art of conductor and magnet technologies. The goal is to illustrate a close synergetic relationship between evolution of high-field magnets and advancement in superconductor technology. The paper is organized in three parts: (1) the basics of RE123 CC fabrication technique, including latest developments to improve conductor performance and production throughput; (2) critical issues and innovative design concepts for the RE123-based magnet; and (3) an overview of noteworthy ongoing magnet projects.

“…A protective Ag layer of a few micrometers and a thicker Cu protection and stabilization layer complete the conductor [76]. The textured template is created by one of two basic methods, either by texturing the buffer layer by ion beam assisted deposition (IBAD) [67]- [71], [77], or inclined substrate deposition (ISD) [78], [79], or by deformation texturing the metal substrate with the rolling assisted biaxially textured substrate approach [72]- [74] and applying epitaxial oxide buffer layers (trademarked RABiTS by Oak Ridge National Laboratory, Oak Ridge, TN).…”

“…The X-ray pole-figure FWHM of recent IBAD-MgO coated conductors is much better than for IBAD-YSZ, being of order 2-4 and, thus, genuinely approaching single crystal structure for the YBCO overlayer [70], although performance so far does not fully reflect this unusually high degree of texture, and achieving the required atomic level surface roughness over long lengths has proven challenging. The inclined substrate deposition (ISD) process is more rapid than YSZ-IBAD, since there is no resputtering during deposition, but in work to date, the texture is not as high [78], [79]. ISD may also permit simpler buffer structures.…”

“…This increases the difficulty for fabrication of high-quality YBCO on ISD-MgO substrates. High current-carrying YBCO films were deposited on ISD-MgO substrates by pulsed laser deposition (PLD) using yttria-stabilized zirconia (YSZ) and ceria double buffer layers [10]. The utilization of the double buffer on ISD-MgO resulted in a unique orientation relationship between the YBCO and ISD-MgO.…”

YBCO-coated conductors with high current-carrying capability are desirable for electric power transmission applications. Inclined-substrate deposition (ISD) is capable of producing high-quality biaxially textured template films, which are important for fabrication of YBCO-coated conductors. We have grown biaxially textured ISD-MgO template films on flexible metallic substrates at deposition rates of 2-10 nm/sec. Columnar grains with a roof-tile-shaped surface structure were observed on the ISD-MgO films. X-ray pole figure analysis revealed that the ISD-MgO film is biaxially textured and its c-axis is titled at an angle from the substrate normal. Strontium ruthenium oxide (SRO) buffer films were epitaxially grown on ISD-MgO by pulsed laser deposition prior to the deposition of YBCO. Low -scan full-width at half maximum (FWHM) values of 6 and 7 were observed for YBCO and SRO, respectively. T c of 91 K with a sharp transition and transport J c over 1.4 MA cm 2 at 77 K in self-field were measured on YBCO coated conductors grown with ISD MgO architectures using a SRO buffer.Index Terms-Coated conductor, inclined-substrate deposition, pulsed laser deposition, SRO buffer, YBCO thin film.
