<title>Applications of x-ray and neutron capillary optics</title>

Abstract

Discovery that wide energy and angular control of x ray and neutron trajectories can be achieved with high efficiency by the use of shaped arrays of hollow capillaries has made possible important new applications in science, medicine, and industry. These include medical diagnostic imaging, medical therapy, analysis of the composition and structure of materials, x-ray microscopy, x-ray astronomy, industrial process and fault analysis, and x-ray lithography. The status and prospects for this remarkable range of possibilities is summarized in this report.
