How a grain boundary found billions of dollars of minerals

Colloquium | April 29 | 4:15-5:30 p.m. | LeConte Hall, Room #1 | Canceled


Cathy Foley, Chief of Materials Science & Engineering, CSIRO

Department of Physics


One of the most successful uses of high temperature superconducting (HTS) devices known as SQUIDs has been their use in mineral exploration. This talk will review the development of HTS grain boundary Josephson junctions fabricated using the “new” ceramic material discovered in 1987 and how this grain boundary junction is the basis of a range of devices used for mineral exploration, unexploded ordnance detection, THz imaging and more recently SQUID arrays for telecommunications. The talk will also cover the steps taken to commercialize the mineral exploration HST SQUID systems and how they have been able to detect over $6B of minerals deposits world wide.
