The detector The position sensitive neutron detector (PSD) is a set of 3He tubes. The assembly can be moved inside the detector tank to adjust the instrument resolution. When the photo was taken, not

The sample chamber The sample can be placed either in sample chamber (opposite) under vacuum and at low temperature or in a furnace.

(png - 81 Ki) BRISP - TOF Spectrometer for Small Angle Inelastic Scattering BRISP is a new concept thermal neutron Brillouin scattering spectrometer which exploits the time-of-flight technique and is

A general view BRISP is an inelastic neutron scattering spectrometer optimized for small-angle experiments (neutron BRIllouin SPectroscopy) at thermal energies. This time-of-flight instrument is aimed

John Allibon, Bachir Ouladdiaf and Silvia Capelli at work on CYCLOPS. A general view By june 2009, CYCLOPS recorded its first Laue patterns. Less than 5 seconds were enough to get excellent data from

The monochromator BRISP offers the choice between 3 large monochromators made of a set of carefully aligned single crystals of graphite or copper.
