Abstract
Ion-beam-assisted deposition (IBAD) is a promising method for preparation of biaxially textured templates for YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) coated conductors. For the purpose of practical applications, many groups make efforts to obtain long and high-performance YBCO superconducting wires based on IBAD templates. In our laboratory, long IBAD template tape fabrication using a reel-to-reel system was developed and up to now, we have fabricated a 220-m-long tape successfully and 103-220 m tapes have been obtained steadily. On these IBAD template tapes, high critical current (I/sub c/) performances were demonstrated and a large I/sub c/ value of 182 Amps was attained with pulsed laser deposited YBCO conductors on 46 m in length. These values give a product of I/sub c//spl times/L over 8000 Am.
