Energy transition

Shifting away from nuclear energy, expanding solar and wind power, generating energy from biomass, reducing energy consumption. Switzerland is committed to becoming climate-neutral by 2050. An ambitious goal, which has become more urgent than ever due to the increasingly challenging geopolitical situation. How can a sustainable and resilient energy supply for Switzerland be established over the coming years? What's the optimal way to use renewable energy sources? What new technologies are especially promising? At PSI, researchers are seeking answers to these crucial questions.

Hotlabor

Public Tour Hot Laboratory

Discover the Hot Laboratory nuclear facility during our guided tour, a unique experimental facility in Switzerland for the nuclear technology investigation and analysis of highly radioactive materials. This is supported by a well-developed infrastructure in terms of safety, analysis, and preparation, with unique laboratories at your disposal.

Ein Strahlkanal des SwissFEL

Public Tour of the SwissFEL

The SwissFEL is one of only five X-ray laser facilities worldwide that can generate hard X-rays in laser quality and make them available for research. During our tour, we will learn about the operation and main research objectives of the X-ray laser and then take a guided walk to view the key components of the 700-meter-long facility.

Protonentherapie

Public Tour Proton Therapy

Proton therapy is a form of radiation therapy used to destroy cancerous tissue with charged particles, specifically protons. Protons are particularly well-suited for this purpose because they deliver their greatest effect deep inside the body, directly within the tumor. At the Proton Therapy Center of PSI, we treat more than 400 patients each year. During our tour, we will introduce you to the treatment rooms and explain PSI’s contributions to the development of proton therapy.

Continuum Excitations in a Spin Supersolid on a Triangular Lattice

Magnetic, thermodynamic, neutron diffraction and inelastic neutron scattering are used to study spin correlations in the easy-axis XXZ triangular lattice magnet K2Co(SeO3)2. Despite the presence of quasi-2D “supersolid” magnetic order, the low-energy excitation spectrum contains no sharp modes and is instead a broad and structured multiparticle continuum. Applying a weak magnetic field ...

Best practices for harnessing operando X-ray absorption spectroscopy in electrocatalytic water splitting studies

X-ray absorption spectroscopy (XAS) has found applications in a range of fields including materials, physics, chemistry, biology and earth science. XAS can probe the local electronic and geometric structure, such as the average oxidation state, coordination environment and interatomic distances, surrounding an element of interest. Thus, XAS is a valuable tool to inform catalyst design by tracking catalyst evolution under operating conditions, for example, via providing dynamic snapshots of the essential information.

Reentrant multiple-q magnetic order and a “spin meta-cholesteric” phase in Sr3Fe2O7

Topologically nontrivial magnetic structures such as skyrmion lattices are well known in materials lacking lattice inversion symmetry, where antisymmetric exchange interactions are allowed. Only recently, topological multi-q magnetic textures that spontaneously break the chiral symmetry, for example, three-dimensional hedgehog lattices, were discovered in centrosymmetric compounds, where they are instead driven by frustrated interactions. Here we show that ...

3D image of a magnetic skyrmion

Skyrmion topology quantified in 3D

Researchers from an international collaboration between the United States of America and Switzerland have performed three-dimensional magnetic imaging of a magnetic skyrmion using soft X-ray laminography. This allowed for the investigation, in three dimensions, of the topological profile of the magnetic skyrmions.
