Description:
Tapered glass capillaries have successfully condensed hard x-ray beams to ultrasmall dimensions providing unprecedented spatial resolution for the characterization of materials. A spatial resolution of 50 nanometers was obtained while imaging a lithographically prepared gold pattern with x-rays in the energy range of 5 to 8 kiloelectron volts. This is the highest resolution scanning x-ray image made to date with hard x-rays. With a beam 360 nanometers in diameter, Laue diffraction was observed from the smallest sample volume ever probed by x-ray diffraction, 5 x 10(-3) cubic micrometers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bilderback, D H -- Hoffman, S A -- Thiel, D J -- RR01646-10/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):201-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cornell High Energy Synchrotron Source, Cornell University, Ithaca, NY 14853.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284671" target="_blank"〉PubMed〈/a〉
