Abstract

The LNCMI, the national French high magnetic field facility, provides high fields generated mainly by resistive magnets. Because of the forecast increasing price of electricity, LNCMI has a strong incentive to participate to the development and characterizations of HTS conductors in view of their use for the generation of strong field. Latest YBCO coated conductors have improved properties showing a great potential with that respect, without excluding Bi2212 and MgB2 for particular cases. We present the existing set-up to measure short straight or VAMAS type coil samples at variable temperature and high field up to 30 T, and some measurements obtained on different HTS conductors, Bi2212 round wires and YBCO coated conductors. We also report on the first results obtained at 18 T with a pancake coil made of commercial YBCO coated conductor tapes on a newly developed solenoid test bench.

Abstract

Key components for the power transmission and distribution for the future grids are superconducting cables. The energy network in highly populated areas will soon fully benefit from this technology, in particular for the retrofitting of the existing cables. However retrofitting the existing grid in underground structures (pipes, pits, turn), requires cables as small a diameter as possible. The HTS cable core is generally manufactured by laying tapes around a former with a diameter of about 25 mm to prevent any damage to the tape during the cabling and the handling operations. However in this configuration, the former cannot be used to transport the current. This triggered a new approach in cable design involving round 2G HTS wires with a diameter from 1 to 2 mm. They can be assembled to build a small cable core with a high ampacity. The benefits of this new wire design on power cables are discussed. The first results on different manufacturing processes and the characterizations of the 2G HTS wires are presented. [ABSTRACT FROM PUBLISHER]

Abstract

The second generation (2G) HTS conductors, the YBaCuO Coated Conductors, show very exciting performances in terms of critical currents under very high fields whereas their mechanical properties, the key issues for very high field magnets, are outstanding for the IBAD (Ion Beam Assisted Deposition) route. Preliminary measurements have shown critical currents Ic above 500 A at 15 T and 4 K on commercial YBCO coated conductors. They are now available in reasonable length and manufacturing focus to provide reliable, consistent performance conductors. With these high critical current and tensile strength above 600 MPa, these conductors are very promising for making HTS superconducting coils able to generate very high field. But very few characterizations exist above 20 T. LNCMI is one of the few facilities in the world where such measurement can be performed. [ABSTRACT FROM PUBLISHER]
