In a neutron reflectivity experiment, the intensity of a neutron beam reflected by a surface is measured as a function of the momentum transfer ... collaborations. The ILL is proud to be leveraging its powerful neutron beam in despatching novel techniques in the field. ...

ground-breaking experiments [1-3] with ultracold neutrons (UCN). The animation shows the principle of the experiment. This made use of ultra cold neutrons (UCNs) bouncing on the surface of a mirror and selected ... selected so that their vertical speed is extremely low. The neutrons are confined in a well with gravity the attractive force (neutrons ...

excellent neutron properties, making them highly efficient for neutron monochromators. Their small lattice spacing and strong reflectivity make them ideal for selecting short-wavelength neutrons (l < 1.5 ... characteristics make polarised ³He neutron spin filters (NSFs) highly efficient and a very "clean" technology for polarised neutron ...

Improving neutron flux is of little value if the scattered neutrons cannot be detected efficiently with the required spatial and temporal resolution. High-quality detectors are essential for optimal instrument ... to push the boundaries of neutron detection, keeping ILL at the forefront of this field. Contact Bruno Guerard Head of Service ...
