A simulated experiment The incoming polychromatic neutron beam (wavelength around 2.2 Å) is backscattered on the monochromator (Bragg reflexion on a crystal lattice) with a high monochromaticity (ener

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

What can neutrons do for your science? The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton. It also forms part of the nucleus of an atom. T

Intro Cryogenics Dilution cryostats Key points Producing cold using 3He/4He dilution In classic dilution cryostats the liquid helium component (4.2 K) and the dilution component are combined in the sa

IN22 at work The aim of the experiment presented here was to measure the neutron scattering from liquid indium . This was never measured before since the expected scattering signal is nearly zero for
