Neutron channeling in a nonmagnetic planar waveguide

TL;DR

This paper studies neutron propagation in a tri-layer planar waveguide, measuring how neutrons are channeled and comparing experimental results with theoretical calculations to understand neutron behavior in such structures.

Contribution

It provides the first experimental measurement of neutron channeling length in a nonmagnetic planar waveguide and compares these results with theoretical models.

Findings

Neutron channeling length varies with guiding channel width.

Experimental results align with theoretical calculations.

Demonstrates feasibility of neutron channeling in nonmagnetic waveguides.

Abstract

We investigate neutron propagation in a middle layer of a planar waveguide which is a tri-layer thin film. A narrow divergent microbeam emitted from the end face of the film is registered. The neutron channeling length is experimentally measured as a function of the guiding channel width. Experimental results are compared with calculations.
