A Workshop to Commemorate the Career of Professor Archie Campbell, held at University of Cambridge

A Workshop to Commemorate the Career of Professor Archie Campbell, held at University of Cambridge

October 5, 2007 (H7).  The “Campbell Conference” was held at the Department of Engineering, Christ’s College and Corpus Christi College on 11th to 13th September 2007 - to celebrate the career of Professor Archie Campbell, who retired from the Department of Engineering, University of Cambridge, on 30th September2007.  The conference was organized under the joint chairmanship of David Cardwell (University of Cambridge), Harald Weber (ATI, Vienna) and David Larbalestier (University of Florida). Professor Campbell made significant contributions to studies of flux pinning in type II superconductors, ac losses and understanding the critical state in superconducting materials during his life-long and distinguished career in the field, which spanned over 40 years. He pioneered the so-called Campbell technique for investigating the penetration of flux in bulk superconductors and, together with late Prof. Jan Evetts, authored in 1972 the subject-defining monograph “Flux pinning in Type II superconductors” (Adv. Phys21, 199, 1972).

The conference venues represent Archie’s Cambridge career (his undergraduate and postgraduate Colleges, and his Department).  Figure 1 shows Archie (left side) at a break during the conference, listening to arguments of Dr. Helmut Brandt of Max Planck Institute in Stuttgart, Germany.

The central theme of the Campbell conference was flux pinning in type II superconductors (Archie's Ph.D. project!), and included materials, properties and applications of all forms of superconductor. More than 70 colleagues from around the world attended the conference, and every continent was represented. The program consisted of 27 invited lectures within the conference themes, including a guest lecture of the Cambridge Philosophical Society (given by Professor David Larbalestier of the High Field Magnet laboratory, University of Florida).

The proceedings, including most lectures, were published as a special edition ofSuperconductor Science and Technology, volume20, No. 9, (2007),and presented formally to Archie at the conference dinner.

Highlights of the conference included reports of significant progress in the development of characterisation techniques of type II superconductors, such as flux line imaging (Kes, University of Lieden), new processing techniques for engineering of nanoscale flux pinning sites (Driscoll, Cambridge and Matsumoto, Kyushu), recent studies of critical current density (Gurevich, Florida and Durrell, Cambridge), state of the art coated conductor technology (Freyhardt, Gottingen and Amemiya, Yokohama) and ac losses in type II materials (Majoros, Ohio).   The complete program of this successful conference can be viewed at:
