“…Pulsed laser deposition (PLD). The PLD process, widely used in the development of the CC technology, has been recently optimized by various manufacturers (Bruker, Fujikura, SuperOx and Sumitomo) and scaled up to production lengths [11,16,20,21,26]. 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.…”

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.

“…Results are presented for a YBCO-RABiTS sample which is a 0.63 thick YBCO film grown by a ex situ process using evaporated precursors on a -RABiTS tape (50 ) [8] and a second YBCO-IBAD sample prepared by depositing 1 thick YBCO film by high rate pulsed laser deposition (PLD) on /IBAD-YSZ (1 /Ni-Cr stainless steel substrate (100 ) [9]. Bending tests have been performed on both samples.…”

We present a comparative analysis on tensile strain tolerance of critical currents for IBAD and RABiTS coated conductors. These measurements have been performed with a recently developed methodology based on dc-magnetization measurements, which enables us to analyze the grain and grain-boundary critical current densities simultaneously. We show that the percolative grain-boundary critical current density may be reduced by 50% with deformations of 0 32% and 1% for RABiTS and IBAD, respectively, while the grain critical current and thus the pinning properties of the grains are not affected by the deformation process.
