The Selby Lecture 2001

"Big Science and Little Science at Synchrotron Light Sources in the Twenty-First Century"

by Professor J Keith Moffat

(University of Chicago)

at 8:00 p.m.

on Monday, 28 May

in Chemistry Lecture Theatre 1,

Sandy Bay Campus, University of Tasmania

Synchrotron light sources are now accepted as essential tools for research in a wide range of disciplines including chemistry, biology, molecular biology, environmental analysis, polymer science, surface science and biophysics.  They are also used industrially for X-ray lithography to produce micro-electronic components, and have clinical applications in new techniques for the diagnosis of coronary disease by X-ray angiography.  These diverse applications depend on the ability of synchrotron light sources to emit light of unprecedented intensity at wavelengths ranging from the very short (‘hard’ X-rays) to the very long (infra-red).  The synchrotron light beams are emitted in short pulses separated by adjustable intervals, are plane polarised, and are highly parallel. 

This year’s Selby Lecture explores, in non-specialist terms, the reasons why synchrotron light sources have become such powerful accessories for research and technology.  It also addresses the question, how the allocation of resources to “Big Science” facilities can be balanced against the requirements of conventional “Little Science” experiments in the researchers’ home laboratories.  As an active researcher as well as director of a state-of-the-art facility, the lecturer is uniquely qualified to describe both recent synchrotron-based research and the likely trends of further developments. 

The 2001 Selby Fellow, Professor J Keith Moffat, is Louis Block Professor of Biochemistry and Molecular Biology at the University of Chicago.  Until recently he was also Director of the Consortium for Advanced Radiation Sources at the Advanced Photon Source, Argonne National Laboratory.  He obtained his first degree in physics at the University of Edinburgh, and his doctorate in protein crystallography at the University of Cambridge.
