Focusing neutrons with a lobster-eye optic

Square-channel capillary, or 'Lobster-eye' arrays have been shown to be the optimum geometry for array optics. This configuration leads to a novel class of conditioning devices for x-ray and neutron beams. We present the first result of the focusing of neutrons with a lead glass square-channel array. This array, designed for soft x-rays, performs comparably with neutrons. Finally, we describe a novel method for the fabrication of glass square channel arrays.
