Sans2d can be used to examine size, shape, internal structure and spatial arrangement in nanomaterials, ‘soft matter’, and colloidal systems, including those of biological origin, on length scales of between* 0.25-300 nm. SANS does not locate individual atoms but rather looks at the larger structures they form. This gives important insights into many everyday materials and biological systems.
* for comparison, a human hair is about 100,000nm in diameter!
- Nanoscience: Nanoparticles and liposomes, green chemistry, liquid crystals.
- Complex mixtures: Detergent molecules used in commercial products.
- Materials: Plastics, composites, metal all rocks, magnetic materials.
- Biological macromolecules: Nucleic acids and proteins.
- Wide Q-range (0.02 < Q nm-1 <20); most is accessible with one instrument configuration.
- Five 2 m guide sections with variable collimation apertures.
- Two moveable 1 m2 detectors giving the most detector area on any SANS instrument in the world and almost 77,000 pixels.
- High-flux at sample (3-10 times LOQ on TS1, depending on Q-range).
- Small sample size/volume (<15 mm diameter or only 0.3-3 ml).
Did you know?
Inside the green blockhouse the detectors are housed in a cylindrical vacuum tank 3.25 m in diameter and 13 m long; this could hold enough petrol to let a regular compact car drive over a million miles! To stop the neutrons colliding with air molecules the tank is evacuated to 1/2000 of normal air pressure.
