Simulated experiment A polychromatic (white), neutron beam is partially monochromatised by the two counter-rotating disc choppers, generating a packet of neutrons which then falls upon the monochromat

One of the choppers The inside of the detector tank Some parts of the instrument When the shielding is open for maintenance, one can see the choppers, the inside of the detector tank and even the focu

A general view of the instrument The photo shows the location of IN4C in the reactor hall. The instrument itself is hidden below a heavy concret shielding.

IN4C - High-flux time-of-flight spectrometer IN4C is a high-flux time-of-flight spectrometer used for the study of excitations in condensed matter. It works in the thermal neutron energy range (10-100

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

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

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

A view of the instrument housing By 2009, the instrument GRANIT was being built in the reactor hall of the ILL. We see here its housing located on the left side of the guide shielding and close to the

Principle of the experiment Long-living centrifugal quantum states. a) The observed scattering probability as a function of neutron wavelength λ and deviation angle φ. b) Theoretical simulation of the
