Developments in modern neutron spectroscopy have led to typical sample sizes decreasing from few cm to several mm in diameter samples. We demonstrate how small samples together with the right choice of analyser and detector components makes distance collimation an important concept in crystal analyser spectrometers. We further show that this opens new possibilities where neutrons with different energies are reflected by the same analyser but counted in different detectors, thus improving both…

This design challenges two accepted norms of high resolution indirect neutron spectrometers: it uses large mosaic pyrolytic graphite crystals instead of nearly perfect silicon crystals to select the final neutron energy, and it operates well away from the normal backscattering condition 2φ ≈ 180° instead using 2 φ = 160°.

Neutron guide shielding for the BIFROST spectrometer at ESS

We report on the study of fast-neutron background for the BIFROST spectrometer at ESS. We investigate the effect of background radiation induced by the interaction of fast neutrons from the source
