An overview is provided of the 15 neutron beam instruments making up initial instrument suite European Spallation Source (ESS), and being made available to user community. The ESS source consists a high-power accelerator target station, providing unique long-pulse time structure slow neutrons. design considerations behind structure, moderator geometry layout are presented. 15-instrument two small-angle instruments, reflectometers, an imaging beamline, single-crystal diffractometers; one for...
The use of nonlinear tapered guides is becoming more common in advanced neutron scattering facilities around the world. Elliptical offer promise high performance not only as focusing devices but an efficient way to transport neutrons over long distances. Here, analytical expressions determine their are derived and discussed. Under certain conditions, increase flux delivery observed with increasing guide length, due angular spread reflected guide. limited by distance between source entrance,...
The degree of order in $\mathrm{Fe}\text{\ensuremath{-}}\mathrm{Al}$ intermetallic alloys has an important influence on their magnetic properties. Moreover, the deformation ordered causes a dramatic increase magnetization. If deformed are heated, properties decrease again. reordering process was monitored by neutron diffraction, M\"ossbauer spectroscopy, and calorimetric measurements ${\mathrm{Fe}}_{70}{\mathrm{Al}}_{30}$ crushed alloy. This indicates that occurs two stages. In first...
Fe–Al alloys around the concentration of 30 at. % Al show very interesting magnetic properties. Alloys with this present inhomogeneities and their evolution temperature is also because they a reentrant spin-glass behavior at low temperatures. Small-angle neutron-scattering measurements were performed in Fe69.5Al30.5,Fe70Al30, Fe70.5Al29.5 range 4–300 K. Even though change Fe content small, response variation quite large. The results that samples have evolve temperature. Only Fe-richest...
Polarised neutron beams are used in disciplines as diverse magnetism,soft matter or biology. However, most of these applications often suffer from low flux also because the existing polarising methods imply filtering one spin states, with a transmission 50% at maximum. With purpose using all neutrons that usually discarded, we propose system splits them according to their polarisation, flips match direction, and then focuses sample. Monte Carlo (MC) simulations show this is achievable over...
To boost the science case of MIRACLES, time-of-flight backscattering spectrometer at European Spallation Source (ESS), an optimized neutron guide system, is proposed. This systematic study resulted in enhancement transport cold neutrons, compared with previous conceptual design, wavelengths ranging from λ = 2 Å to 20 along 162.5-m distance source sample. maintained undisturbed main focus instrument, viz, carry out quasielastic and inelastic scattering (QENS INS) experiments on a large...

The new research reactor at ANSTO (OPAL) is operating with seven neutron beam instruments in the user programme and three more under construction. design provides for expansion of facility to eighteen instruments, much basic infrastructure already place. However, an guide system needed further instruments. For this purpose, several possibilities are consideration, such as insertion multi-channel benders existing cold guides or construction a elliptic guide. In work Monte Carlo (MC)...
