POLARISATION SPECTROMETER Russian patent published in 2013 - IPC G01N23/223 

FIELD: physics.

SUBSTANCE: polarisation spectrometer includes a gamma- or X-ray source, a concave target, a diaphragm with a hole, a sample holder, a detector with a collimator directed towards the sample, and recording equipment, the input of which is connected to the output of the detector, wherein the target is caved-in on a cylinder; the focus of the source lies on the edge of the cylinder; the device also includes a second sample holder, a second diaphragm, a second detector with a collimator and recording equipment, a collimator with narrow slits or channels for forming a primary beam, perpendicular to the axis of the cylinder, wherein the detectors and the holes in the diaphragms lie, first, on the edge of the cylinder diametrically opposite the source and, secondly, at diametrically opposite points of two spheres of the same size; the spheres are also spaced apart on both sides, and the sample holders are configured to place the samples on said spheres under secondary beams passing through the holes in the diaphragms.

EFFECT: high efficiency and output, enabling analysis of identical or different spectral ranges of two samples of representative mass simultaneously or successively using two detectors.
