Paper Abstract

Five different measurement techniques for experimental estimation of focal spot sizes in X-ray tubes are described. They are: the pinhole, the slit, the edge, the scanning and the grid- wire methods 11-61. The same techniques can be used for experimental estimation of focal spot sizes in X-ray lenses. We are developing methods using magnification, high resolution and digital detection of a precise edges response to obtain quantitative estimates of focal spot dimensions for X-ray tubes and lenses for the energy range from 6 to 60 keV. Agreement between the wire and the edge methods is rather good, while three others give only rough estimations, when we use them for measuring focal spot sizes in the range from 0.0lmm to 0.05mm.
