The sample can be a liquid, a bunch ... diffraction", when a polycrystalline lump of material, often ground to a fine powder, is placed in the beam. Neutrons are scattered at ...

multiple or higher-order Bragg scattering (polarising crystals). The beam polarisation obtained with an NSF is perfectly homogeneous over the beam profile and there is no g-background created by the absorption ... polarised gas acts as a neutron spin-filter (NSF) both for creating the polarisation of the incident beam and for analysing the ...

SuperSUN is an ultracold neutron source situated at the end of the H523 beamline. This line delivers a beam of cold neutrons (including 9A wavelength neutrons), which are converted into ultacold neutrons (UCNs)

grown at above 700 °C onto a gadolinium gallium garnet (GGG) substrate by means of laser molecular beam epitaxy. The diffusion-assisted formation of a Ga-rich region at the YIG/GGG interface is demonstrated
