- Jun-ichi Shimoyama (Aoyama Gakuin University)
- Boris Maiorov (Los Alamos National Laboratory)
Coated conductors (CCs) of YBa2Cu3O7 (YBCO) have emerged as the most attractive opportunity to reach unique performances for large scale superconducting power applications and high field magnets, though reducing the cost/performance ratio continues to be a key objective at present. It is still particularly necessary to develop faster growth in order to increase the CC throughput....
STI continues to improve our High Temperature Superconducting (HTS) ReBCO coated conductor production and metrology techniques to deliver higher-performance & lower-cost superconducting products to our customers in key application markets. In this talk, we’ll cover (3) areas of our recent focus to enhance our product qualities; Long length in-field metrology for 2G HTS characterization,...
YBCO based 2G HTS wires are being manufactured at MetOx on pilot production scale at this time with the ultimate goal of providing the industry with high performance and low-cost wires for magnet and cable applications. MetOx uses IBAD/MOCVD process and currently coats 12 mm wide tape. At this time MetOx wires have 50 m single piece length and 77K/SF Ic of 400-500A. Two different recipes have...
Dramatic improvement in in-field performance of thick 2G-HTS tapes has been recently achieved in >4 m thick REBCO films over a wide range of field and temperatures, as demonstrated by the resulting engineering current densities, JE, of over 15 MA/cm2 at 30 K, 3 T and over 5 kA/mm2 (0.5 MA/cm2) at 14 T, 4.2 K, which is over five times higher than that of Nb3Sn. The ability to control film...
The University of Houston and AMPeers have developed round REBCO wires of 1.3 to 1.9 mm in diameter that can retain nearly 100% of its critical current even when bent to a radius of 15 mm. Such a small bending radius is a requirement of canted cosine theta coils that are being developed for accelerator magnets. Such small diameter wires and excellent bend strain tolerance have been made...
