ISEC 2005—Conference summary and comments on SQUIDs and coolers

Abstract

On the basis of the 'wrap-up' talk given at the ISEC 2005 meeting, recent progress in SQUIDs and cryocoolers will be summarized in a subjective and selective way. It will be shown that there is a return of some earlier SQUID applications with a higher level of system quality. The essential progress in cooler technology and reliability will result in a new standard of cooler integration and cryopackaging. As a consequence of insufficient funding and the lack of a superconducting electronics industry, applications will be limited to niches where non-superconducting alternatives fail. Further efforts in research and development will be required but they will be based on system-oriented concepts.

Characterization of La-doped YBCO superconducting films deposited by DC magnetron sputtering at various off-axis geometries

“…4), 5) The fabrication process for the HTS high speed sampler and HTS single-flux-quantum (SFQ) digital circuits has been studied with the aim of realizing next HTS products consisting of more complicated structures. 6),7) For application to power cables, transformers and motors, coated conductors using YBCO have been intensively developed in recent years.…”

Deposition of SmBCO superconducting films on Zr-rich BaZrO3-buffered MgO substrates

“…The YBa 2 Cu 3 O y (YBCO) superconductor is the most promising material for applications of high-T c superconductors (HTS) at liquid nitrogen temperatures, because of its T c higher than 77 K, chemical stability, low anisotropy in superconducting properties and so on [1][2][3]. At present, products using YBCO such as microwave filters and SQUID magnetometers are commercially available [4,5].…”
