In the present 5-year national project since 2003, the development of YBCO coated conductors (CC) has advanced rapidly. The high performance processing group of SRL-ISTEC and Fujikura Ltd. has been working on the long tape of the PLD-YBCO superconductor on the IBAD-Gd2Zr2O7 buffered substrate tape. Very recently the SRL group achieved the highest value on the product of Ic x L in the world, 51,940 Am (212 m x 245 A). Fujikura Ltd. also realized the longest buffered substrate tape of 500m long IBAD tape and obtained a 200 m long coated conductor with Ic value of 88 A. In the low cost processing group using MOD, CVD and so on, the high Ic value of 525 A was obtained by SRL using the TFA-MOD method on the IBAD substrate. The 45m long TFA-MOD tape was also obtained with the Ic value of 155 A by Showa Electric Wire and Cable Company. Similarly 100- 200 m class long tapes were also obtained by the MOCVD (Chubu Power Electric Company) and PLD-HoBCO processes (Sumitomo Electric Industry Ltd.). Both groups above are further developing for the final goal of 500 m long tapes with the Ic of 300 A/cm-w at the production rate of 5 m/h. Furthermore, the feasibility study for the application has started due to the above success of long tape production. Several kinds of preliminary experiments using long coated conductors are now in progress for the power applications such as (1) Power Cable, (2) Transformer, (3) Motor and so on.

Ybco Coated Conductors

We report on recent progress towards the continuous deposition of YBCO Coated Conductors (CC) by thermal co-evaporation. This is an attractive vacuum technique thanks to the simplicity, low cost and intrinsic uniformity over large areas. Recently, we published the in situ preparation route of 1 μm thick superconducting YBCO films deposited onto CeO2 buffered Ni biaxially textured tapes using a reel-to-reel system; end-to-end critical current densities Jc's at 77 K and self-field, measured by transport measurements are in the 1-2 MA/cm2 range for 1 m. long samples, with zero-resistance Tc= 87 K and transition widths DTc<3 K. In spite of the very good CC’s performances reported by a number of laboratories all over the world, several steps must be optimized in order to limit the CC production costs, in particular concerning the complexity of the CC architecture and the choice and optimization of the YBCO deposition technique. We specifically address the following critical points regarding: 1) the in situ oxidation of the YBCO layer using a novel supersonic nozzle, 2) the deposition by thermal or e-beam evaporation of thick crack-free CeO2 buffer layers and 3) the scaling-up of the deposition process using a new multichamber system.
