MONOCAPILLARY OPTICS DEVELOPMENTS AND APPLICATIONS

Hollow glass tubes are in use at Cornell High Energy Synchrotron Source (CHESS) as X-ray optics in the 4 to 25 keV range to take large diameter, fairly parallel X-ray beams and compress them into smaller diameter, more divergent beams for various kinds of X-ray applications. The optics come in two forms: 1) multibounce condensing capillaries for making submicron diameter beams and 2) one-bounce imaging capillaries with working distances of 20 to 50 mm from the tip of optic to the focal spot. The preliminary results of the applications, from X-ray fluorescence imaging to protein crystallography, are briefly described in this paper.
