3D imaging for planar samples with zooming
Researchers of the Paul Scherrer Institut have previously generated 3-D images of a commercially available computer chip. This was achieved using a high-resolution tomography method. Now they extended their imaging approach to a so-called laminography geometry to remove the requirement of preparing isolated samples, also enabling imaging at various magnification. For ptychographic X-ray laminography (PyXL) a new instrument was developed and built, and new data reconstruction algorithms were implemented to align the projections and reconstruct a 3D dataset. The new capabilities were demonstrated by imaging a 16 nm FinFET integrated circuit at 18.9 nm 3D resolution at the Swiss Light Source. The results are reported in the latest edition of the journal Nature Electronics. The imaging technique is not limited to integrated circuits, but can be used for high-resolution 3D imaging of flat extended samples. Thus the researchers start now to exploit other areas of science ranging from biology to magnetism.
Computational Fluid Dynamics Group
The Computational Fluid Dynamics (CFD) group conducts research in application and development of numerical simulation techniques pertinent to safety of nuclear reactor simulations. The group’s portfolio covers the methods at different scales, ranging from entire systems modeled by the system code RELAP, through containment analysis with GOTHIC, and computational fluid dynamics method applied to components, down to molecular dynamic simulations.
