Elaboration of station DICSI at KCSR and NT for studies on structural dynamics of biological objects

Development of X-ray equipment for small-angle investigations of biological nanostructures on synchrotron radiation

“…The bending moments are produced by a couple of forces induced by movable supports, which act on the plate edges and are located at equal distances a from the fixed supports. In our previous paper [10], we demonstrated that, in order to produce a cylindrical X-ray optical zoom with an optimum focal distance, both supports should be displaced by the distance δ d at once. The displacement is reckoned from the planar location of the bent plate with the use of the following general relationship: where U and V are the distance between the front end of the focusing element and the synchrotron source and the distance between the front end of the focusing element and the detector, respectively, and τ is the glancing angle of the beam with respect to the operating surface of the element.…”

“…The diffraction movie technique was developed using a one-coordinate detector with a high time resolution [10,23]. Furthermore, we also designed prototypes for two-coordinate recording in the same manner.…”

“…The DICSI experimental monochromatic station was implemented at the K1.3a beamline of the Siberia-2 storage ring at the Kurchatov Center for Synchrotron Radiation and Nanotechnology (Russia). The design of this station was based on the results of the previously performed experimental and theoretical developments [8,10].…”

Synchrotron radiation studies of non-crystalline systems

“…In addition to the existing beam lines with SAXS/WAXS capability several new instruments were recently built, [3][4][5][6] or older ones upgraded, 7,8 and more are being commissioned. Apart from instruments which also have spectroscopic capabilities 9 this has, however, had little impact on the type of measurements being performed.…”

Instrumental and methodical approaches to the study of the transformation of nanostructural parameters in biological objects

“…The development of instrumentation allowed us to create X ray diffraction stations at the operating chan nels of SR sources [10][11][12][13][14][15][16][17][18][19][20][21][22][23] designed for the following experiments: study of the structure and structural dynamics of skeletal muscle and epithelial tissues in normal and pathological states; study of the natural and engineering silk constructions; and the effect of the high frequency electrosurgical welding (HF weld ing) of biological tissues.…”
