IN20 - Thermal neutron three-axis spectrometer with polarisation analysis IN20 is a thermal beam three-axis spectrometer for inelastic scattering experiments in various sample environments (eg. magnets

thermal neutron induced reactions. It is composed of a highly collimated halo-free pencil neutron beam impinging on a stable or radioactive target surrounded by a high resolution High Purity Germanium

q-range q max /q min in one instrument setting. High magnetic fields, up to 17 T at the sample position, beam polarization and 3 He spin analysis, facilitate and expand studies of magnetism and allow a more

ght (TOF), polarised beam This is achieved by using an S-bender polarising the TOF beam in a selectable wavelength range with high polarisation. The instrument resolution and beam shape remains flexible ... GISANS possible.

provided by a Δλ/λ = 0.01 combined to 1D slit collimation or 2D pinhole collimation provides a flexible beam geometry adapted to various sample shapes and sizes and scattering geometries. This flexibility allows

than 36m upstream a velocity selector in the guide placed on a movable in/out table ensures a clean beam, preventing higher order reflections from the monochromator and reducing the background at the sample

measures the deviation at small angles (much less than one degree to several degrees) of a neutron beam due to structures of small size in the sample. "Small" means dimensions of a few tenths to about 100

D3 - The Spin Polarised Hot Neutron Beam Facility It is a very versatile diffractometer for magnetic structure analysis. It offers several set-ups: a high field set-up for 1D polarimetry up to 10 Tesla ... configuration Separation of coherent and spin-incoherent scattering in hydrogenous liquids Non-polarized beam with high magnetic field ...
