PUS
The powder neutron diffractometer PUS is a high-resolution instrument for characterization of the atomic structure of new materials, mainly in the form of powder samples. Neutrons have several benefits over X-rays, which are most commonly used for powder diffraction. Most notably, neutrons are scattered similarly by light and heavy elements, which makes it possible to accurately locate elements such as hydrogen, lithium and oxygen in materials with much heavier metals. This is utilized in fundamental studies of materials for a wide range of green-energy applications such as hydrogen storage, Li-ion batteries, catalysis and fuel cells.
Neutrons also have a magnetic moment which makes them a unique probe for determination of the magnetic structure of materials.  Samples can be measured in a controlled atmosphere in the temperature range 9 – 1300 K.

SANS

The Small-Angle Neutron Scattering instrument is well suited for structural characterization of nanoparticles, emulsions, gels and colloids with agglomerate or particle size in the range 2-100 nm. The instrument is particularly useful as a non-destructive probe for the study of biological structures or polymer/peptide-based nanoparticles intended for medical purposes, such as in drug delivery. Materials can be studied in their natural state, for example as nanoparticles in suspension, but the option of contrast matching makes it possible to accurately characterize specific parts of the particles separately (e.g. only the core in a core-shell particle). The instrument is also relevant for energy materials, and has been used extensively to characterize particle sizes and nanoporous structures of such systems. The sample temperature can be adjusted between 0 and 250 degrees C. Possibility for using high-pressure CO2.

ODIN

The ODIN instrument is a new, high-resolution diffractomater with four two-dimensional detectors covering a scattering angle range of about 5-140 degrees. Furnaces and cryostats may be used to control sample temperature.

R2D2

This is a test beamline that can be used to accommodate different types of neutron and gamma detectors and neutron optical devices, and is also used for testing neutron shielding materials. The instrument is used in collaboration with ESS and ESS-partners. The main goals of R2D2 are the testing of new detector technology, including neutron convertor technology, electronic response and data acquisition, as well as the study of the transmission properties of neutron shielding materials. The beamline versatility also provides the perfect setup for the testing of new developments in optics, such as guide behavior under an incident neutron beam, and the development of new experimental techniques and testing protocols.

DIFF

DIFF is a high intensity, low resolution diffractometer optimized for studies of liquids and amorphous materials. The data acquisition time is short, and relatively slow processes of phase transformations and structural changes can be studied in real time. Examples of materials that have been studied include liquid crystals, nanocarbon, cellulose nanocrystals and battery materials.

Instrumentation under construction:

NIMRA

NIMRA (Neutron IMaging and RAdiography) is the upgraded neutron radiography station at JEEP II. It is designed to have an L/D ratio of about 300 and a FOV of 15 cm x 15 cm. A state-of-the-art sample stage and a new digital neutron detector system will allow 2D and 3D imaging (tomography) with a resolution down to 50 µm. Planned for completion during fall 2019.

NIMRA is intended for studying energy materials (e.g. hydrogen storage systems, fuel cells and electrolyzers, heat storage units) as well as flow in porous media (e.g. clays, concrete). Applications within other material classes, systems and research areas (e.g. cultural heritage, paleontology) are also envisioned and actively pursued.The upgrade preserves the previous capabilities of running neutron radiography analysis of active samples (e.g. nuclear fuel elements).

FREYJA

FREYJA will be a neutron reflectometer of conventional design for studies of structure of thin films, interfaces and membranes. It is still in the design phase and planned for completion in 2020.

NEST

NEST will be a neutron strain scanning instrument to be used for non-destructive mapping of strain in mechanical parts. This is important to understand how materials are affected by processes such as welding, machining, casting, extrusion or 3D-printing. The instrument is currently in the design and planning phase and will be operational from the end of 2020.
