Abstract
A method for manufacturing the monolithic capillary X-ray lens, comprising the steps of Drawing a hollow glass raw-tube into monocapillaries in a heating furnace by a drawing tower; Stacking monocapillaries into a symmetric mould to form a multibundle; Feeding the multibundle into the heating furnace to be heated at uniform speed or variable speed; Drawing the multibundle by a drawing tower at uniform speed and variable speed to form a first integrated lens billet; Cutting the monolithic lens billet into desired shape according to usage to form said first monolithic capillary X-ray lens. A monolithic capillary X-ray lens produced by using said method comprises a plurality of X-ray channels passing from one end through another end, and is a single glass solid formed by melting together the walls themselves of said X-ray channels. An X-ray diffractometer employing said lens comprises an X-ray source, a sample, a detector, a high voltage power supply, an amplifier, a pulse analyzer, a scaler, a ratemeter, a computer, an X-ray source control system and a goniometer, wherein the monolithic capillary X-ray lens are disposed between the X-ray source and the sample and/or between the sampl…
