Session

DescriptionPtychographic x-ray tomography is the highest resolution x-ray imaging technique available for generic samples, achieving resolutions down to 4 nm. Since its development at the Paul Scherrer Institute in 2010, it has been applied to a wide variety of systems, with applications in catalysis, materials science, engineering, the life sciences, and physics. The field as a whole is currently facing a major opportunity, combined with a major challenge because synchrotrons around the world, including the Swiss Light Source, are upgrading to fourth-generation storage rings. These new synchrotrons provide far higher brightness and massively increased data rates, making it possible to study larger systems but also brings computational challenges related to dealing with the ever-growing data rates. This minisymposium includes talks from experts on ptychographic tomography reconstructions who work in different fields, and who champion different approaches to making use of these new, brighter sources. By including perspectives from a variety of application areas, with a shared focus on the challenge of managing data rates, we hope to drive forward the conversation and identify the most promising approaches for the next generation of beamlines and reconstruction tools.
