  • SMOOTH hollow glass capillaries can be used to guide neutrons by multiple reflection at grazing angles along the inner walls. Here we show that a concentric arrangement of bent capillaries makes it possible to focus and increase the flux density of a neutron beam—a phenomenon that will have applications in areas such as prompt-gamma activation analysis and neutron depth profiling.
