Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Selecting the parameters for slit collimators forming narrow beam of high-energy X-ray radiation Osipov S.P., Sidulenko O.A., Kas’yanov S.V., Kas’yanov V.A. The article suggests an algorithm for parameters selection of slit collimator (thickness, slit opening, slit length) to form the narrow beam of high-energy X-ray radiation. It gives an example of parameters calculation for tungsten collimating insertion into biological shielding from photons source for X-ray radiation of maximal energy equal to 1…10 MeV. Key words: radiography, slit collimators, narrow beam of high-energy X-ray radiation, tungsten collimating insertion. Контактный телефон (3822) 72-70-19. E-mail: osip1809@rambler.ru
