dynamic modes in condensed matter by measuring the energy exchange between a monochromatic neutron beam and the sample. Applications Study of dynamics and relaxation properties in condensed matter exploiting

condensed matter by measuring the energy exchange between a monochromatic neutron beam and the sample. From the continuous, "white" beam delivered by the H15 neutron guide, a specific wavelength (and thus incident ... Fermi chopper pulses this monochromatic beam, setting the time t 0 of its interaction with the sample. A timer then measures the ...

Three intense neutron beams are extracted from a neutron guide by an assembly of three monochromators and are focused horizontally onto the sample. Each monochromator delivers a beam of distinct energy and ... and, thus, of distinct velocity due to different Bragg-scattering conditions. The neutron beams are pulsed by a Fermi chopper which allows ...

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.

Computer drawing of UFO A simulation of UFO beam-trajectories Multi-analyzer IN12-UFO As a further option, IN12 will be equipped with a 2-dimensional position sensitive detector and an array of fifteen ... fifteen analysers which can be rotated and positioned individually in order to map the scattered beam on a user-chosen path in Q-space. ...

monochromator crystals which select an initial wavelength out of it, directing this beam onto the sample. The monochromatic beam arrives on the sample - for example a single crystal - and is scattered in many ...
