Neutron guide system for guiding neutrons with greater wavelength, has neutron guides which are arranged non-linearly, and are formed as mirror in inner surface at specific angle with respect to neutron beam axis

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a neutron guide system that uses two specially shaped, non-linear neutron guides with reflective inner surfaces angled precisely to help guide neutrons, especially those with longer wavelengths, efficiently from a source. The neutron guides change in cross-section and are arranged so as to optimize the transfer of neutrons while minimizing loss.

Patent Abstract

The neutron guide system has a source (Q) for generating neutrons. Two neutron guides are arranged non-linearly, and are provided with narrowing and widening cross-sections. The neutron beam emerging from the source is passed to small opening of the first neutron guide and the large opening of the second neutron guide. The inner surface of the neutron guide is formed as a mirror (S) arranged at slight angle of 0.01[deg] to 5[deg] with respect to neutron beam axis (Z).
