new approach. This TAS option combines a set of analyzers and detectors in a very compact design. It can be installed on the ILL TAS instruments IN8, IN14 and IN20. Applications Determination of magnetic

inelastic scattering. When the sample is heated, the magnon gap (> 5 meV) closes and fluctuations can be observed. A single night of measurements on IN20 was enough to obtain this result. Ref: A.Boothroyd

to have a reasonable chance that discrepancies between real and simulated data can be fully understood. a molten metal can be easily simulated using ab-initio techniques while a solid material is more difficult

for inelastic scattering experiments in various sample environments (eg. magnets up to 15 T). It can be equipped with single-analyser-detector or Flatcone (an inclinable multianalyser-detector to study

observed with neutrons in 2000 But why neutrons? As gravitation is a very weak force, quantum phenomena can only be observed using very small masses and without any external perturbation. Ultra cold neutrons ... perturbations, their lifetime is long enough to separate the quantum states and finally because they can be selected so that their energy ...

local dynamics in complex materials like polymers, membranes and biological samples Some interest can be found in the study of spin dynamics of disordered magnetic materials.

materials and compounds - hydrides, zeolites and catalysts, biological matter etc. High quality spectra can be recordered even from small samples due to very high luminosity of this spectrometer. An example

dynamics of a polymer are differently influenced by spatial restrictions in a porous material. It can also be seen that the crystallisation (upwards jump for bulk) is suppressed when confinement volume

Spectroscopy Inelastic excitations can be measured on IN16 with extremely high energy resolution. Many examples for backscattering on rotational tunneling systems can be found in Prager, M. & Heidemann ... excitations, which arise in the example shown from nuclear hyperfine splitting of Nd nuclei in NdGaO3, can only be resolved with sub-μeV energy ...

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 focusing monochromator.
