Description
We have studied the ion-beam-assisted deposition (IBAD)-MgO process using a large IBAD system with a large ion source. Using the large IBAD system, we successfully fabricated a long-length IBAD-MgO tape (1 km) at a production rate of 1 km h-1. We have also studied a process to deposit CeO2 films directly on IBAD-MgO tapes. It is revealed that the CeO2 film is fully textured at about 100 nm. GdBa2Cu3O7-x (GdBCO) film was fabricated on a 180 m-long CeO2 /IBAD-MgO film. Its critical current (Ic) and current density (Jc) were over 300 A and 3 MA cm-2 at 77 K, self-field.
