SANS-1

SANS-1 is dedicated to studying nanoscale length scales of 10 to 3000 Å, particularly adapted for the needs of materials research and magnetism. It allows hosting a wide range of different sample environments, including a bespoke dilatometer for in-situ rapid quenching/heating and stress analysis.

• Precipitates and segregation in alloys
• Rapid quenching/heating and deformation of alloys
• Defects in materials, surfactants, colloids
• Ferromagnetic correlations in magnetism
• Anode materials and functionality of batteries
• Magnetic domains & nanoparticles
• Polymers, proteins, biological membranes, viruses, ribosomes and macromolecules
• Superconducting vortex lattices
• Large emergent magnetic structures such as helical magnets and skyrmion lattices

During thermal operation without the cold source, the focus will be on studies of shorter correlations up to 1000 Å in a mostly non-polarised set-up using shorter wavelengths and shorter collimation distances.

• Standard sample changers with 22 positions, 11 positions for the magnet and 11 positions with thermostat (-10 – +200°C)
• MLZ suite of high-temperature furnaces up to 1900°C
• Deformation-rig with heating: 100 kN
• Set of magnets (2.5 T and 5 T horizontal, 7.5 T vertical, 12 T vertical (TAS magnet))
• MLZ suite of cryostats, including low-T inserts
• Dilatometer DIL 805 A/D/T Quenching Dilatometer [2]
• NB Nanoscale, D5 HF-Generator for magnetic hyperthermia [3]
