About 20 students, postdocs and industrial researchers attended a week-long school on electron diffraction at the National Center for Electron Microscopy at Lawrence Berkeley Laboratory, Berkeley, California, USA, starting on 19 April 2004. Lectures by L. Marks, J. Zuo, W. Sinkler, J. C. H. Spence, U. Dahmen, A. Eades and R. Kilaas covered all aspects of electron crystallography, including CBED, SAD, diffuse scattering, powder patterns for phase identification, combining SAD with HREM, and basic theory, from dynamical theory, Bloch waves, channelling and multislice, to direct methods.
