Abstract

X-ray focusing using square channel capillary arrays is reviewed. We present some experimental results obtained using a variety of array configurations and we deduce that channel misalignment and surface roughness are the prime factors limiting the performance of these devices. We present results obtained using a stacked array of commercial precision bore square tubing and deduce that the reflectivity from these unetched surfaces is superior to that from etched micro-channel plate blanks. The improved surface quality implied by this reflectivity result is confirmed using atomic force microscopy. We also present results of a new drawing technique that we have developed.
