Applications in
superconductivity
Dr Barry began work in superconductivity when the field of high
temperature superconductors was very new. He carried out research
work in this area both at Arizona State University and at the
University of Queensland. Dr Barry was a principal investigator
in two major superconductor projects at the University of Queensland,
"Development of Continuous Superconducting Wire Coils” and
"Superconducting components for the Electricity Supply Industry".
At the present time, and as part of the PicaMS consulting business, Dr
Barry is working with a Gold Coast company on a superconducting
magnetic shield application. Expulsion of magnetic fields is a
fundamental property of superconductors. The consultancy involves
modelling, and deriving a theoretical framework, which aids in the
design of magnetic shields and provides a systematic means for analysis
of performance.
