The Paul Scherrer Institut (PSI) has a leading position in X-ray microscopy and has pioneered a new lensless imaging technique called "scanning X-ray diffraction microscopy" or "Ptychograpy". We have recently extended this 2D imaging technique to 3D. Ptychographic computed tomography delivers quantitative 3D images of both amplitude and phase at a resolution of currently 150 nm in user operation. The large penetration depth of hard X-rays is ideal for imaging thick (tens of microns) specimens. This allowed starting several research projects in the field of bone research and bio-nanoporous materials in general, but also in the field of materials science, like cement and polymer research. However, the scientific application is currently limited by the available instrumentation: the resolution needs to be improved and cryogenic sample preparation and protection against radiation damage is required for imaging in life science. “OMNY” (tOMography, Nano, crYo stage) is a pioneering project to design and fabricate a new endstation for the Swiss Light Source (SLS) at PSI to overcome current limitations. OMNY will enable non-destructive, quantitative nano-tomography based on scanning X-ray microscopy in a cryogenic sample environment. An instrument like OMNY is beyond state of the art. OMNY will permit to address sample systems like soft tissue that can be imaged element specific and non-destructive in their native state. OMNY will become a unique 3D analytical tool available to a broad user community. OMNY is not limited to biological samples: it will also permit nanotomography on solid samples like cement, integrated circuits and magnetic structures, inter alia. OMNY will be implemented at the cSAXS beamline at SLS. The experimental environment that will be created by this new type of endstation also satisfies well the requirements of future SwissFEL applications. This renders the development and use of OMNY an important step towards future use of SwissFEL.
