When these neutrons and other lower energy neutrons from (n,xn)...
The NM-2023 design is optimised for modern 1′′3He counters and is benchmarked against a 6-NM-64 (the leading number denoting the number of BP28-BF3counters, in this case a 6-counter NM-64). MCNP transport code simulations of the new design indicate an equivalent counting efficiency to...
where Σ, the macroscopic cross-section, cm− 1; x, the path length (distance the neutron beam travels), cm; I0, the intensity of incident neutron beam, i.e., the number of particles passing across unit area in unit time, n cm− 2 s− 1; I, the intensity of the neutron be...
Nature Reviews Methods Primers volume 1, Article number: 70 (2021) Cite this article 7297 Accesses 36 Altmetric Metrics details Abstract Small-angle scattering (SAS) is a technique that is able to probe the structural organization of matter and quantify its response to changes in external cond...
A 3.5 T split coil wound on an aluminium former is attached to the bottom of a liquid 4He vessel (Fig. 6). A ∅ 49 mm stainless steel tube with an aluminium end cap runs axially through the helium bath and then in vacuum down to the centre of the magnet (Fig. 6). It ...
Reference samples USGS GXR 1-6, USGS-AGV-1,NES-SRM-1362a,and CCRMP SY-2 and SY-3 were also used.Predetermined volumes of solution standards were pipetted onto plastic films or onto circular pieces of filter paper and the films or the papers were packed into aluminium foils of high ...
Number of studies involving neutron diffraction analysis in thermal spray coatings remain limited, partly due to limited number of such strain measurement facilities globally, and partly due to difficulty is applying neutron diffraction analysis to measure residual strain in the thermal spray coating micro...
To characterize the microstructure of the two alloys a set of characteristic parameters (e.g. volume fraction, average radii, precipitate number density, etc.) were obtained using relations between the moments rof the size distribution N(r). The model proved particularly suited to characterize the...
positioned as close to the detector as possible, minimising image blurring and variations in beam path length through the box during scanning. The mounts were made of aluminium, with Teflon tape used to protect the surface of the boxes. Both these materials have low neutron attenuation ...
At the centre of the tribometer an aluminium shaft holds a polyether ether ketone (PEEK) roller partially submerged in an oil bath. Using a belt transmission system, the roller can be rotated with surface velocities between 1.4–7.2 ×10−1 m s−1. A 55 × 55 × 10 (l × w × ...
