ICMC-02 - RE123 Conductors Processing and Properties
Invited Oral Presentation
RE-Ba-Cu-O (REBCO, RE=rare earth) coated conductors are being produced today by at least six companies world wide in lengths over 500 meters. REBCO coated conductors are being tailored specifically to the requirements in high magnetic field applications as well as AC applications. We have developed heavily-doped REBCO conductors with 15 – 25 mol% Zr addition with excellent properties in...

ICMC-02 - RE123 Conductors Processing and Properties
Invited Oral Presentation
SuperOx manufactures and markets high current, low cost 2G HTS tapes for HTS devices. Our core manufacturing technology includes the IBAD-MgO texturing on strong, non-magnetic Hastelloy substrates to make buffer templates and the PLD growth of the GdBCO layer.
At present we offer tapes with single lengths over 300 m and Ic (77 K, s.f.) of 300-500 A/12 mm and 100-150 A/4 mm. SuperOx...

ICMC-02 - RE123 Conductors Processing and Properties
Contributed Oral Presentation
For high current REBCO superconductors in high magnet fields with currents in the order of 50 kA, single coated conductors must be assembled in a cable. The geometry of such a cable is mostly such that combined torsion, axial and transverse loading states are anticipated in the tapes and tape joints. A set of experimental setups as well as a convenient and accurate method of stress-strain...

ICMC-02 - RE123 Conductors Processing and Properties
Contributed Oral Presentation
Solder joints between YBCO coated conductors and normal metal traces have been analyzed as part of an effort to develop a robust HTS lead assembly for a spaceflight mission. Measurements included critical current and current transfer profiles. X-ray micrographs were used to verify proper solder flow and to determine the extent of voiding. SEM of cross-sections with XDS analysis were crucial...

ICMC-02 - RE123 Conductors Processing and Properties
Contributed Oral Presentation
We will report recent experimental observations of persistent current in closed loops made out of the currently manufactured coated conductors. Two types of coated conductors were investigated. One was developed for high magnetic field application and the other for cable applications. Data was taken in the range of 23K to 38K with the persistent current being induced by field cooling the loops...
