We discuss our progress toward depositing IBAD MgO as a template for subsequent deposition of YBaCuO{sub 7-} (YBCO) high temperature superconductors on metallic substrates. We have refined the process by improving substrate preparation and by using reflected high-energy electron diffraction (RHEED) to monitor the growth of IBAD MgO films. Here we present results on our work to optimize the IBAD MgO process for continuous processing of meter lengths. High quality IBAD MgO has been deposited on moving metal tape for use in coated conductor fabrication. By incorporating optimized processing parameters, we have been able to deposit films on moving metallic substrates with in-plane mosaic spreads near 8{sup o}. The subsequent pulsed laser deposition (PLD) of 1.5 m thick YBCO films has resulted in superconducting transport critical current densities >1MA/cm² (75K,SF) on small area samples.
