Patent ID: 7149279

Claim:
Detecting unit for X-ray diffraction measurements, comprising: a position-sensitive detector and a collimating system located in front of a window of the detector, said collimating system being in a form of a honeycomb structure comprising multiple tubular channels for transmittance of diffracted X-ray radiation, adjacent tubular channels of said multiple tubular channels having walls fused together, the tubular channels converging towards inlet end face of said collimating system and having outlet ends forming outlet end face of said collimating system directed towards the window of said position-sensitive detector, the tubular channels having rectilinear longitudinal axes, the outlets of the tubular channels in said outlet end face of said collimating system being arranged in several rows along the window of said position-sensitive detector, said walls of the tubular channels being made of material absorbing X-ray radiation, or having a coating of such material, the detecting unit further comprising an adjusting mechanism for adjusting position of the collimating system relative to the window of said position-sensitive detector, the adjusting mechanism being configured for providing rotation of the collimating system around an axis perpendicular to a plane passing through a middle row of the rows of the tubular channels.
