Ê1.3a - Station for time-resolved small-angle diffraction
X-RAY MOVIE (DICSI)

The small-angle station DICSI is dedicated to research of the dynamics of medico-biological objects by monochromatic X-rays with the use of high-speed diffraction methods in wide angular range.

X-ray optical scheme

DICSI parameters

	Energy range, keV	5 ÷ 12,5;
	Wavelength resolution, (Dl/l)	10-3 ÷ 10-4
	Angular resolution, rad	10-4
	Diffractogram registration range:
	- for the structure of molecular level, nm	1,0 ÷ 100,0
	- for the structure of subcellular level, µm	1,0 ÷ 4,0
	Optical magnification range	0,17õ ÷ 0,38õ

Status - 2005

• Experimental schemes for wide class of medico-biological objects are under development and testing. Configuration of the basic scheme is based on SR-beam focusing with crystal-monochromator (in sagittal plane) and total reflecting mirror behind (focusing in meridional plane).
• The systems for registration of X-ray diffraction patterns are based on the use of one-coordinate fast detector (OD-3 type, 10 MHz), two-coordinate systems for imaging with the use of CCD and/or CMOS-sensors and storage screens with posterior readout (Image plate - detectors).
