Intensity of x-ray microbeam formed by a hollow glass pipe

Abstract

X-ray microbeams have been produced by utilizing hollow glass pipes. It has been observed that the intensities of ten x-ray lines (from 6.93 to 19.6 keV) transmitted through 250-mm-long hollow glass pipes of inside diameters of 27.4, 23.0, and 18.8 μm range from 1.9 to 2500 times greater than intensities reduced by inverse-square attenuation.
