Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A compound refractive lens made of nickel and designed for focusing high‐energy synchrotron X‐rays is presented. The lens consists of 600 parabolic grooves and focuses X‐rays in one plane only (planar lens). The lenses made and investigated by us earlier exhibited low transmission and irregularities in the focused beam profile. Since then, improvements in lens manufacturing technology have been made. The present lens gives an almost Gaussian profile and produces four times higher intensity at its maximum compared with the intensity of primary X‐ray beams of 174 keV.</p> </abstract>
