Reel-to-Reel Processing of Buffer layers and YBCO on Textured Substrate
High Tc superconducting tapes based on YBCO Coated Conductor have been extensively studied to develop the processing techniques for application. In this paper, two self-designed reel-to-reel deposition systems (Sputtering and PLD) were installed. Continuous deposition of multi-layer CeO2/YSZ/Y2O3 buffer layers were carried out on biaxially textured NiW substrate using reactive sputtering. YBCO films were coated on the CeO2/YSZ/Y2O3 buffered NiW substrate by continuous PLD subsequently. To achieve high current carrying capacities, combinations of various deposition conditions were explored. X-ray diffraction measurements show good in-plane and outplane texture in buffer layers and YBCO films. The transition temperature of the YBCO was 89 K and the critical current is over 50 A at 77 K in 1 meter long YBCO tapes.
