Abstract
Conditioning neutron and X-ray beams is best achieved with glancing-incidence reflective optics. Square micro-channel arrays offer an increasingly practical geometry for this implementation. We present results for focussing neutrons with two such arrays, one with channel size of 32 μm, which places us truly in the microscopic regime. These two arrays, designed for soft X-rays, perform comparably with neutrons.
