SINQ – Swiss Spallation Neutron Source

Header 2

Neutron scattering techniques are highly versatile and powerful tools for studying the structure and 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. In addition to scattering, non-diffractive methods like imaging techniques allows for non-destructive inspection of materials and components, providing information on their internal structure, composition, and integrity with growing relevance also for industrial applications.

The spallation neutron source SINQ is a continuous source - the first and only one 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 operates as a user facility, meaning that scientists and research groups from around the world can apply for beamtime to conduct experiments using its various neutron instruments.

The recent proposal deadline passed on 15 May 2025. The results of the evaluation may be expected in late July. 

The next call is planned for fall with a submission deadline on 15 November 2025.

Hydration- and Temperature-Dependent Rotational Dynamics and Water Diffusion in Nanocellulose

Nanocellulose is a promising alternative to fossil-derived materials, but its development is hindered by a limited understanding of cellulose–water interactions. Herein, quasielastic neutron scattering (QENS) is used to investigate how hydration and temperature affect the localized rotations in cellulose nanocrystals (CNC) and the diffusion of mobile water. QENS reveals ...

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Fast neutron imaging is a promising technique for visualizing objects containing dense, mixed light-and-heavy-elements materials, such as combustion engines, nuclear fuel assemblies, and fossils, where X-rays and thermal neutrons are ineffectiv. However, the limited efficiency of current detection technologies hinders their widespread adoption. Recoil proton detection ...

Neutron imaging in 2D and 3D as a powerful tool to investigate electrolyte degradation and plating mechanisms in sodium-ion batteries

To develop durable and high-performance sodium-ion batteries, it is crucial to understand the degradation processes taking place during electrochemical cycling. This study presents the first demonstration of visualizing the effects of electrolyte degradation in sodium-ion batteries, via 2D and 3D neutron imaging thereby visualizing the degradation of the cells. The experiment  ...
