SwissFEL: a perfect habitat for the black mortar bee
For the construction of the SwissFEL facility in 2013, around five hectares of forest were cleared and transformed into a new habitat for flora and fauna. Biologists and forest engineers have now assessed the results of the renaturization project and are excited about the progress to date.
Wait and see, and grow crystals
At PSI, researchers decipher the structure of the proteins in bacteria and viruses. This knowledge can aid, for example, in the development of drugs against infectious diseases. But before the investigation can begin, an extremely tricky problem has to be solved: the crystallisation of the molecules.
Harnessing components from the optical internet for programmable spectroscopy
A novel concept for extracting information from spectra where traditional post-processing procedures fail, dubbed ‘software-defined spectroscopy’, offers a fresh approach to high-resolution terahertz spectroscopy. The new method implements an ‘optical comb’ and combines it with a programmable modulator, all using components from the optical internet.
Measurements at PSI enabled detailed understanding of genetic scissors
PSI congratulates Emmanuelle Charpentier and Jennifer Doudna on winning this year's Nobel Prize in Chemistry. Experiments at the Swiss Light Source SLS in 2013 made it possible to elucidate the structure of the protein complex CRISPR-Cas9.
Two-color snapshots of ultrafast charge and spin dynamics
In a joint research effort, an international team of scientists lead by Emmanuelle Jal (Sorbonne Université) performed a time-resolved experiment at the FERMI free-electron laser to disclose the dynamic behavior of two magnetic element of a compount material in only one snapshot. The X-ray Optics and Applications group developed a dedicated optical element for this experiment that is usable with two different photon energies (colors) simultaneously.
PSI - member of the Microsoft Quantum Network
The PSD is a research partner in the Microsoft Quantum Network, which is a broad community of individuals and organizations collaborating with Microsoft to advance a comprehensive quantum ecosystem, develop practical solutions, and build a robust quantum workforce.
The institutions of scientific excellence are partnering collaboratively with Microsoft to pursue the advancement of quantum computing research, development, and education. The large scale facilities at PSI, in particular the Swiss Light Source, offers unique characterizations techniques to shed light on the secrets of functional materials.
First light in the SwissFEL Maloja endstation
The first endstation at the SwissFEL Athos soft X-ray branch is rapidly developing and on track for first experiments in 2021.
Customising an electronic material
PSI scientists have investigated a material that could be suitable for future data storage applications. They have manipulated the crystalline structure of their sample while measuring how this affects the material’s magnetic and electronic properties.
Analytical Research Infrastructures of Europe (ARIE) join forces to face COVID-19 and other viral and microbial threats
After the joint position paper published as a pre-release in July, in which the Analytical Research Infrastructures of Europe (ARIE) presented their plan to tackle HE Missions, the ARIE enhanced its cross-border, multidisciplinary collaboration to offer Europe a strong and valid weapon against the present COVID-19 challenge and other potential viral and microbial threats.
