[Experience in the use of synchrotron radiation for the x-ray study of biopolymers]. / Opyt ispol'zovaniia sinkhrotronnogo izlucheniia dlia rentgenograficheskogo issledovaniia biopolimerov

ABSTRACT

The results of methodical work, carried out on the sources of synchrotron radiation (SR) with the aim of using SR as a powerful source of X-rays for studying biopolymer structure, are presented. The questions of monochromatization are considered. The technique designed for photoregistration of diffraction patterns within the wide range of scattering angles is described. X-ray diffraction patterns of feather ceratin, collagen and striated muscle are obtained with exposure periods ten times less than those in the case of X-ray tubes. The high resolution of diffraction lines, the absence of parasitic phone and the presence of reflections within the wide range of scattering angles are characteristic of these patterns.
