More details about the invention

The invention relates to technical physics, namely to detectors for detecting thermal neutrons. The essence of the invention lies in the fact that a gas-filled detector for measuring the small-angle scattering of thermal neutrons has cathodes made in the form of a system of grounded concentric rings of different diameters, wherein each ring is made of flexible resilient material, outer and inner sides of each ring are coated with metal-coated layer; the inner layer of the ring is divided by electrically insulating layers into sectors which act as separate cathodes mutually oriented at the geometrical centre of the detector; grounding is performed through outer ring layer, which serves as additional cathode; for the anode thread holder in the zone of the electrically insulating layer of each ring holes are made; each anode and each sector cathode are individually connected to analogue electronics, forming two-dimensional detectors; analogue electronics is located inside the housing volume.
EFFECT: technical result is the high accuracy of measuring the location of inhomogeneities in the analysed sample.
