Advances in YBCO coated conductor technology

چکیده
Processes for producing both the YSZ template film by IBAD and the YBCO superconducting film by PLD at 1 m lengths have achieved Ic values of 122 A and Jc values of 1 MA/cm2. Improvements have been made in all stages of the process. Variations of Ic along the length of the 1-m samples stimulated development of a new in-field Ic measurement capability. The use of MgO as an IBAD template film has made great progress and can potentially decrease the time to produce the template film by more than an order of magnitude. A combination of electrical and microstructural investigations are being made to understand and improve the properties of the YBCO coated

Ac Loss in Striped (filamentary) Ybco Coated Conductors Leading to Designs for High Frequencies and Field-sweep Amplitudes
AC losses of YBCO coated conductors are investigated by calculation and experiment for the higher frequency regime. Previous research using YBCO film deposited onto single-crystal substrates demonstrated the effectiveness of ‘striping’ or filamentary subdivision as a technique for AC loss reduction. As a result of these studies the idea of subdividing YBCO ‘coated conductors’ (YBCO, overlayer, ...
متن کاملReel-to-reel Texture Analysis of Hts Coated Conductors Using a Modified Gadds System
High temperature superconducting (HTS) materials need a high degree of texture over kilometerlong lengths in order to carry the maximum amount of supercurrent for electric power industry applications. One way to achieve the high degree of texture is with the coated conductor architecture. The coated conductor is comprised of the HTS layer epitaxially grown on a textured oxide buffer layer on a ...
متن کاملSuperior properties of SmBCO coated conductors at high magnetic fields and elevated temperatures
In addition to the well investigated YBa2Cu3O7 d (Y-123, YBCO) compound, many other rare earth-123 compounds are candidate materials for the production of coated conductors. Sm-123 seems to be an excellent alternative because of its higher transition temperature (Tc) and higher critical current densities (Jc) in external magnetic fields. Because of the fast decrease of Jc in YBCO at elevated te...
متن کاملTHE EFFECT OF STRAIN ON GRAINS AND GRAIN BOUNDARIES IN YBa2Cu3O7−δ COATED CONDUCTORS (POSTPRINT)
The role of grains and grain boundaries in producing reversible strain effects on the transport current critical current density (Jc) of YBa2Cu3O7−δ (YBCO) coated conductors that are produced with metal–organic deposition (MOD) was investigated. The strain (ε) dependence of Jc for full-width coated conductors is compared with that for samples in which the current transport was limited to a few ...

AbstractIn this study, the stress analysis of YBCO/CeO2/YSZ/CeO2/Ni architextured materials under cryogenic conditions was carried out for coated conductor applications. YBCO/CeO2/YSZ/CeO2 multilayer films were fabricated on Ni tape substrate using reel-to-reel sol-gel and Pulse Laser Deposition (PLD) systems. The microstructural evolution of high temperature superconducting YBCO film and buffe...
