Spanos Auditorium

This seminar is part of the Jones Seminars on Science, Technology, and Society series.

Atom probe tomography (APT) is a three-dimensional atomic imaging technique. Yet it fails to reach the ultimate in microscopy, which is seeing every atom with high precision in large volumes. This talk will review the state of the art in APT and explore what it would take to reach the next level, which is defined to be atomic-scale tomography (AST). The potential impact of AST on science and technology will be considered.

About the Speaker

Thomas Kelly is a Professor of Materials Science and Engineering at the University of Wisconsin-Madison and Director of the Materials Science Center until September 2001. Tom founded Imago Scientific Instruments to commercialize the local electrode atom probe. Imago was acquired in April 2010 by Ametek, Inc. and is now part of CAMECA. Tom has been active in the fields of analytical electron microscopy, atom probe microscopy, and has brought innovations to the instrumentation and practice. The development of atom-probe tomography remains the principal passion in his career as he seeks to advance the technology and broaden the applicability of the technique. Tom was a Director of the Microscopy Society of America from 2000 to 2002, a member of the Steering Committee of the International Field Emission Society from 2002 to 2008, and is the recent Past President of the International Field Emission Society. He is currently a Director of the Microanalysis Society, is the nominee for President Elect, and is a Recipient of its Presidential Science Award.
