the typical measuring strategy of a three axis spectrometer like IN8. The monochromator selects a beam of neutrons in a narrow energy band. The analyser is positioned to select a scattering direction (related

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

not corrected for higher order contributions. Orange curve: New IN12 with velocity selector in the beam, green curve: additional 60' collimation using only vertical focusing.

polychromatic neutron beam (wavelength around 2.2 Å) is backscattered on the monochromator (Bragg reflexion on a crystal lattice) with a high monochromaticity (energy resolution 10 µeV). The beam is reflected so

Cryocradle is now available to reduce beamtime losses by cooling a sample while the other is in the beam. Cradle attached to the cryocooler ©Ecliptique - L. Thion Langmuir trough Based on a Microtrough G1
