SANS principle Small Angle Neutron Scattering principles Neutron scattering is the process of collision between neutrons emitted by a source and a target which is the studied sample. When the scatteri

PF2 Video The film was displayed at the American Physical Society conference in March 2017.

Pedagogical animations Six animations are shown : without phase shifter (-> no contrast) normal with absorber with spin flipper, vertical analyzer (-> no contrast) with spin flipper, horizontal analyz

A simulated experiment Basics of the so called time-focussing technique Three intense neutron beams are extracted from a neutron guide by an assembly of three monochromators and are focused horizontal

Principle of the spin-echo technique Spin-echo spectrometers are based on the determination of neutron velocities by using the Larmor precession of their spin in a constant magnetic field. This is a t

IN20 and the TASSE spectrometry The movie shows the very first steps of an experiment performed on IN20 in 2008 on parahydrogen. The instrument was operated in the TASSE mode combing both neutron trip

A simulated experiment The incident polychromatic neutron beam coming from the guide H144 passes in the standard set-up a velocity selector and only a selected wavelength band continues through the gu

Doppler monochromator The movie shows the old mechanical Doppler drive of IN16. On IN16B a linear motor Doppler drive (AEROLAS) is in operation. It follows the same principle but achieves higher monoc

Simulated TAS experiment The animation shows the principle of a neutron inelastic scattering experiment with IN20 by means of the classical three axis spectrometry (TAS). The polychromatic beam from t

Working on the instrument This video was recorded on Oct, 2006 during an experiment intitled "Light-induced biological-function related dynamics in bacteriorhodopsin (purple membrane)". The unusual en
