steve kevanSteve Kevan will be joining the ALS management team as Deputy Division Director for Science, effective July 2, 2012. Dr. Kevan, currently Professor of Physics at the University of Oregon, is a longtime active ALS user and has been a member of the ALS Scientific Advisory Council for several years as well as a member, and Chair, of the ALS Users’ Executive Committee.

Dr. Kevan earned his Bachelor of Arts at Wesleyan University in 1976 and his PhD in Physical Chemistry from the University of California, Berkeley, in 1980, where he worked with former LBNL Director David Shirley. In his thesis work he pioneered the photoelectron diffraction technique for determining adsorbate surface structures and applied this to study sulfur, selenium, and CO adsorbed on low-index single-crystal nickel surfaces. After completing his PhD, Kevan worked at AT&T Bell Laboratories where he developed new instrumentation for performing high-resolution angle-resolved photoemission at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory.  He focused in particular on high-resolution studies of intrinsic surface states on metal and semiconductor surfaces, discovering and characterizing many new states. In his final years at Bell Labs, Kevan applied an old idea called “dispersion compensation” to a new high-resolution electron scattering spectrometer.

At the University of Oregon since 1986, Kevan was an early participant in the planning stages of the ALS. He moved his research program, which focused on surface electronic structure and surface Fermiology, from the NSLS to the ALS to take advantage of the constantly improving resolution and capabilities at the facility. In the past decade, Kevan's research activities have increasingly focused on utilizing the high-optical brightness of undulator radiation. He and his collaborators have used the high-coherent flux available to pioneer the soft x-ray analogs of speckle metrology and dynamic light scattering. He led the construction of Beamline 12.0.2.2, which was an early step toward a dedicated and flexible coherent soft x-ray scattering and imaging beamline that is culminating with the construction of the COSMIC facility.
