source the short rotor (25 cm) and high transmission of its velocity selector the relatively large beam cross-section of 55 x 40 mm of the guide H512.

of these collisions are very small, the emitted neutrons are very close to the axis of the emerging beam. This process is thus referred to as Small Angle Neutron Scattering (SANS) In the animation below

es in a single crystal of silicon which has been heat treated for 500 hours at 600°C; the neutron beam was incident along a <100> direction. The central cross arises from the cushion shaped SiO 2 precipitates

a combination of several design features that result in the strongest flux of UCN/VCN worldwide: A beam of very cold neutrons is extracted from ILL's vertical cold source by an optimized neutron guide system ... would be necessary in the case of direct UCN extraction are greatly reduced; furthermore, part of the beam can be used for experiments ...

ILL, scientific users bring their whole experimental apparatus to PF2 to connect it to one of our beam ports. Our source can serve four experiments with UCN (PF2/MAM, PF2/UCN, PF2/EDM, PF2/TEST), and one

- Polarised cold neutron beam facility PF1B is dedicated to the particle and nuclear physics experiments. It provides the strongest polarised and unpolarised cold neutron beam in the world currently available ... Some of the experiments just use its neutron beam, other profit from its many devices needed to polarise, form, characterise, shield or ...

respectively. These detectors, an integral method to detect the events, and the most intense neutron beam in the world, allowed us to measure the asymmetries with a record sensitivity of about 4.10 -8 . Ref

fission fragments or reactions with light nuclei ( 6 Li, 10 B) relative to the incoming polarised beam are catching the eye with the sign of the asymmetry depending on the direction of emission of the

neutron Laue diffraction The Laue diffraction technique is very simple. If placed in a white neutron beam a crystal produces a diffraction pattern which is characteristic of both its lattice symmetry and

reciprocal space, while reducing the background on the detector compared to use of the full white beam.
