Development of RE123 coated conductor by ISD method

High rate deposition of HoBa2Cu3O7-delta (HoBCO) layers using the pulsed laser deposition method were experimented for long high temperature superconducting (HTS) coated conductor. Laser conditions and oxygen ambient during HoBCO deposition were precisely inspected. This revealed that the deposition rate of HoBCO reached to 5 mum/min. Even at such high deposition rate, the J(c) of HoBCO films remained over 10(5) A/cm(2) on the biaxial buffered substrate fabricated by the inclined substrate deposition (ISD) method. Moreover continuous tape production equipments were installed to make a long and flexible coated conductor by ISD method. These equipments will enable us to fabricate of over 100 m long coated conductor. 55 in long coated conductor were fabricated by using these equipments as our first trial of long length fabrication. Evaluation of J(c) distributions of 55 m coated conductor revealed that all parts of 1 m in the 55 in conductor had the J(c) over 10(4) A/cm(2). (C) 2003 Published by Elsevier B.V.
