Abstract

Three film deposition systems (pulsed laser deposition, sputtering, and evaporation) equipped with reel-to-reel metal tape moving apparatus were installed and used to make meter-long coated conductor. Buffer architecture of $CeO_2/YSZ/Y_2O_3$ was deposited on Ni alloy using sputtering, evaporation, and PLD. YBCO superconducting layer was continuously deposited on buffered metal tape by PLD. End-to-end critical current ($I_c$) of 107 A at 77 K, self-field has been achieved in 1 em-wide tape (thickness 0.6∼1.0${\mu}{\textrm}{m}$, tape moving speed 54∼72 cm/hr) over 1 meter length.
