“…2,3) Japan is also leading in peripheral technologies such as the improvement in the in-field I c and/or critical current density (J c ) properties and low-AC-loss technology. Excellent properties of superconducting CCs have also been reported by SuperPower, 4,16) American Superconductor, 5,17) Los Alamos National Laboratory, 18,19) and Oak Ridge National Laboratory in the U.S.A., 20) and by THEVA 21) and Bruker Energy & Supercon Technologies (former EHTS) in Germany. 22) The combinations of the key fabrication processes used to fabricate intermediate buffer layers and superconducting layers are as follows: ion-beamassisted deposition (IBAD) and pulsed laser deposition (PLD); IBAD and metalorganic chemical vapor deposition (MOCVD); rolling-assisted biaxially textured substrates (RABiTS) and metalorganic deposition (MOD); and IBAD and reactive coevaporation (RCE).…”

There are high expectations for coated conductors in electric power applications such as superconducting magnetic energy storage (SMES) systems, power cables, and transformers owing to their ability to contribute to stabilizing and increasing the capacity of the electric power supply grid as well as to reducing CO 2 emission as a result of their high critical-current characteristics. Research and development has been performed on wires/tapes and electric power devices worldwide. The Materials and Power Applications of Coated Conductors (M-PACC) Project is a fiveyear national project in Japan started in 2008, supported by the Ministry of Economy, Trade and Industry (METI) and the New Energy and Industrial Technology Development Organization (NEDO), to develop both coated conductors that meet market requirements and basic technologies for the above-mentioned power applications using coated conductors. In this article, research and development results are reviewed and compared with the interim/final targets of the project, and future prospects are discussed. #

“…The YBCO tapes produced by American Superconductor (AMSC) and SuperPower Inc. (SP SCS12050-copper stabilized and SF12100-non-stabilized) consist of YBCO and buffer layers deposited on a high resistivity substrate based on a reel-to-reel process. The use of biaxially aligned thin films as a buffer over textured or non-textured substrates, avoiding chemical diffusion and decreasing the misorientation between YBCO grains, overcame the weak-link behavior of the superconducting top layers thereby increasing the critical current density of the tape [7]- [12].…”

Several high temperature superconductor (HTS) tapes have been developed since the late eighties. Due to the new techniques applied for their production, HTS tapes are becoming feasible and practical for many applications. In this work, we present the test results of five commercial HTS tapes from the BSCCO and YBCO families (short samples of 200 mm). We have measured and analyzed their intrinsic and extrinsic properties and compared their behaviors for fault current limiter (FCL) applications. Electrical measurements were performed to determine the critical current and the value through the V-I relationship under DC and AC magnetic fields. The resistance per unit length was determined as a function of temperature. The magnetic characteristics were analyzed through susceptibility curves as a function of temperature. As transport current generates a magnetic field surrounding the HTS material, the magnetic measurements indicate the magnetic field supported by the tapes under a peak current 1.5 times higher than the critical current, . By pulsed current tests the recovery time and the energy/volume during a current fault were also analyzed. These results are in agreement with the data found in the literature giving the most appropriate performance conductor for a FCL device (I peak = 4 kA) to be used in a 220 V-60 Hz grid.

“…Some methods demonstrated to produce high critical currents over long lengths include metal-organic deposition [2], pulsed-laser deposition [3], chemical-vapor deposition [4], and electron-beam evaporation [5]. Metal-organic deposition is used in this work with a liquid precursor based on metal-trifluoroacetates deposited on short samples by spin coating or in long lengths by slot-die coating [2].…”

We present our recent results in introducing artificial flux-pinning centers in metal-organic deposited YBa 2 Cu 3 O 7 coated conductors. In particular, we describe methods for creating point-like and planar defects through precursor and process modifications, and linear defects using post-process heavy-ion irradiation. We observe these defects through transmission-electron microscopy. Each type of defect contributes a particular critical-current signature and combinations of defects can be used to tailor the superconductor for specific applications.
