Neutron imaging (NI) is a nondestructive and noninvasive inspection technique with a wide range of potential applications. The fundamentals of this technique need to be improved, particularly in achieving micrometer-scale or finer resolution, which remains a challenging task. Recently, we developed a high-resolution NI device utilizing fine-grained nuclear emulsions (FGNE). The NI of...
One of the key roles that CANS facilities play in the international neutron ecosystem is providing the abundant beam time necessary for developing novel ideas in neutron instrumentation. Over the last two decades, LENS has devoted considerable effort to the development of spin manipulation devices, in particular the Magnetic Wollaston Prisms that have been used for various spin-echo techniques...
We have been developing the RIKEN Accelerator-driven compact Neutron Systems (RANS) since 2011. Two accelerator-based neutron systems and an RI-based neutron salt meter are already being used for daily neutron scattering measurement experiments. RANS-I consists of 7 MeV proton LINAC (425MHz RFQ+DTL coupled) and a beryllium target with a room temperature polyethylene moderator and a...
With a globally shrinking supply of neutron and the NIMBY perception that research reactors face, compact accelerator-driven neutron sources (CANS) are on the rise. CANS have potential to produce an intense source of pulsed neutrons, with a capital cost significantly lower than spallation sources and reactor sources along with much less public stigma. A prototype Canadian CANS (PC-CANS) is...
Neutron scattering remains an indispensable tool for probing the structure and dynamics of matter. To meet the growing demand for advanced neutron capabilities, the French ICONE project is developing a next-generation neutron source based on a high-current compact accelerator (HiCANS). Now in the Technical Design Report (TDR) phase, ICONE's innovative dual-target station design, with tailored...
SANS is a commonly used technique for structural study of materials. However, its effectiveness is often perceived to depend on the availability of high incident neutron flux. In this work, we introduce a data analysis method grounded in the properties of multivariate Gaussian distributions, which accounts for the proximity relationships among detector pixels. This approach enhances the...
