SINQ: The Swiss Spallation Neutron Source
Neutron scattering is one of the most effective ways to obtain information on both, the structure and the dynamics of condensed matter. A wide scope of problems, ranging from fundamental to solid state physics and chemistry, and from materials science to biology, medicine and environmental science, can be investigated with neutrons. Aside from the scattering techniques, non-diffractive methods like imaging techniques can also be applied with increasing relevance for industrial applications.
The spallation neutron source SINQ is a continuous source - the first of its kind in the world - with a flux of about 1014 n/cm2/s. Beside thermal neutrons, a cold moderator of liquid deuterium (cold source) slows neutrons down and shifts their spectrum to lower energies. These neutrons have proved to be particularly valuable in materials research and in the investigation of biological substances. SINQ is a user facility. Interested groups can apply for beamtime on the various instruments by using the SINQ proposal system.

Nanocrystal superlattices as phonon-engineered solids and acoustic metamaterials
Phonon engineering of solids enables the creation of materials with tailored heat-transfer properties, controlled elastic and acoustic vibration propagation, and custom phonon-electron and phonon-photon interactions. These can be leveraged for energy transport, harvesting, or isolation applications and in the creation of novel phonon-based devices, including photoacoustic systems and phonon-communication networks.
Eine Hand wie keine zweite
Eine 3500 Jahre alte Bronzeplastik wird an der Neutronenquelle SINQ des PSI vermessen. Damit können Restauratoren einen einzigartigen Blick ins Innere des Sensationsfundes werfen – und Erkenntnisse über dessen Verarbeitung gewinnen.
Evolution of Magnetic Order from the Localized to the Itinerant Limit
Quantum materials that feature magnetic long-range order often reveal complex phase diagrams when localized electrons become mobile. In many materials magnetism is rapidly suppressed as electronic charges dissolve into the conduction band. In materials where magnetism persists, it is unclear how the magnetic properties are affected.
