Simulation of the Sample Alignment Process for the White Beam Tomography

Nowadays growth of synthetic crystals is a very prospective direction of research activity. However, it is well known that in synthesized crystals there are still many defects and the main idea is to synthesize crystal of ideal form and structure. But in purpose to remove defects first you have to characterize them. This paper describes the method for the characterization of such defects and mainly concentrates on the problem of sample alignment procedure, offering the way to avoid misalignments

Automated control system of extraction column

Extraction column has been analyzed as a control object; its mathematical description has been developed subject to the peculiarities of processing. On the basis of mathematical description the simulation model of column device was developed. Automated control system was synthesized by re-extract density in pulse column. Estimation of control quality supported by the system was carried ou
