We report on the demonstration experiment of the multiple small angle neutron scattering ͑MSANS͒ technique at a 5.6 m long neutron beam line, leading to a q resolution of 3 ϫ 10 −4 Å −1. The MSANS technique is based on two two-dimensional multihole apertures placed at the front end of the collimator and close to the sample, respectively. By choosing the proper MSANS geometry, individual diffraction patterns are superimposed leading to a large gain in intensity. Using MSANS as an option for standard small angle neutron scattering beam lines, the q resolution could be increased to 10 −5 Å −1 without dramatically sacrificing intensity.
We present concepts for two new instruments for steady state or pulsed neutron sources:. An ultra-small small angle scattering option for small angle scattering instruments -the principle might be applied for high resolution reflectometry as well;. A high resolution spin echo option for a long baseline SANS instrument Further we present first data from a new resonance spin echo option, dedicated to enhance the resolution of thermal triple axis spectrometers by 2 orders of magnitude.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
