<title>STEND-70: multifunction arrangement for the x-ray capillary products testing</title>

Abstract

In the report we consider the experimental set-up for measuring the main characteristics of X-ray capillary products in the X-ray energy band ranging from 4 keV up to 60 keV. These characteristic are: 1) the capillary/lens transmission coefficient; 2) X-ray focal spot sizes of lenses and conical capillaries; 3) focal distances of lenses; 4) the transmission coefficient and the scatter reduction factor (for anti scatter grids). The arrangement is designed to allow measuring spectral dependence of the above characteristics. Example of the measurement of the X-ray poly-capillary transmission coefficient is given. The influence of mechanical and electronic stability on the measured values is discussed. Examples of the designed and manufactured gimbal mounts, translation stages, X-ray collimators and X-ray detectors that were produced by IRO in collaboration with 'Kurchatov Institute' are presented.
