Simulation-guided optimization of small-angle analyzer geometry in the neutron backscattering spectrometer SPHERES.
نویسندگان
چکیده
The resolution of neutron backscattering spectrometers deteriorates at small scattering angles where analyzers deviate from exact backscattering. By reducing the azimuth angle range of the analyzers, the resolution can be improved with little loss of peak intensity. Measurements at the spectrometer SPHERES are in excellent agreement with simulations, which proves the dominance of geometric effects.

The safety of a landmine detection system using graphite and polyethylene moderator
Background: Several landmine detection methods, based on nuclear techniques, have been suggested up to now. Neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are the nuclear methods used for landmine detection. In this paper an optimized (safe and effective) moderating structure using an 241Am-Be neutron source for detecting landmines has been invest...

We will use inelastic neutron scattering to examine the quantum rotational dynamics of methyl iodide (also known as iodomethane, CH3I), a textbook example of a symmetric quantum top. The goal of this hands-on measurement is to gain an understanding and appreciation of the backscattering and filter analyzer measurement techniques, get practical experience in obtaining inelastic neutron scatterin...

Bonner spheres system is one of the ways of measuring neutron energy distribution which is often applied in spectrometry and neutron dosimetry. This system includes a thermal neutron detector, being located in the center of several polyethylene spheres, and it is still workable due to the isotropic response of the system which in turn is derived from the spherical symmetry of moderators and the...
متن کاملOptimization of die geometry for Tube Channel Pressing
Since tubes have numerous industrial applications, different attempts are focused on the Severe Plastic Deformation (SPD) processes of tubes. As an illustration, Tube Channel Pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of greater s...
