Overview

Microscopy has made a tremendous impact across biology, physics, chemistry, materials science, and many other scientific fields. Powerful tools such as x-ray crystallography, cryo transmission electron microscopy, and various scanned probe microscopies are routinely used for imaging biological structures, nanoparticles, and surfaces at nanometer resolution and beyond. However, few tools exist that can image thick and non-crystalline structures in three dimensions on these length scales. Lensless x-ray methods such as coherent diffraction microscopy offer one way around these limitations. Coherent diffraction methods have come a long way since the first demonstration in 1999; they have been used to study nanocrystals and biological cells as well as test objects in both two and three dimensions, primarily with synchrotron sources and recently with an x-ray laser. The rapid worldwide growth of interest in this technique is evidence of its potential as a practical tool for microscopy.

This workshop brings together researchers in the life, materials and condensed matter sciences to discuss driving questions that can uniquely be tackled by coherent x-ray diffraction microscopy. The proposed high brilliance ERL facility at APS presents a fabulous opportunity for these experiments. The goal of this workshop is to develop a roadmap through the next decade and to marshall support for a dedicated diffraction microscopy beamline at APS.
