Résumé

The MOD process for producing YBCO-coated conductors using metal trifluoroacetate (TFA) precursors is expected to be a strong candidate as a fabrication process for coated conductors since the TFA-MOD process is a non-vacuum process that has succeeded in the providing of high critical-current density films. In the paper, recent progress in R&D for long coated conductors using TFA-MOD processing is reported. Recently, in order to fabricate long tapes with high performance, continuous reel-to-reel systems have been developed for coating systems and calcinations, and also for crystallization processes. In order to confirm the ability of this continuous reel-to-reel system, the critical-current distribution of a 25-m long tape was investigate. As a result, the uniformity of the textured YBCO layer was confirmed by maintaining a high critical current of over 200 A along the entire tape.
