Wir schaffen Wissen – heute für morgen

The Paul Scherrer Institute, PSI, is the largest research institute for natural and engineering sciences within Switzerland. We perform world-class research in three main subject areas: Matter and Material; Energy and the Environment; and Human Health. By conducting fundamental and applied research, we work on long-term solutions for major challenges facing society, industry and science.

Second beamline for SwissFEL

SwissFEL SwissFEL Technology SwissFEL Experiments

This year the first pilot experiments are starting at the free-electron X-ray laser SwissFEL. The X-ray light generated by SwissFEL will enable a broad spectrum of experiments. Beginning in 2020, a second beamline will provide for a still greater variety.

3-D X-ray imaging makes the finest details of a computer chip visible

Media Releases Materials Research Micro- and Nanotechnology Matter and Material Research Using Synchrotron Light

Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.
