X-RAY DETECTOR OF DIRECT CONVERSION Russian patent published in 2016 - IPC G01T1/24 

FIELD: electricity.

SUBSTANCE: radiation detector (100) comprises a converting element (102) to convert falling high-energy radiation (X) into charge signals, a cathode (101) and a grid (104) of anodes (103), arranged on different sides of the converting element, for generation of electric field (E₀, E_d) in the converting element (102), at the same time the converting element (102) has spatial heterogeneity, as a result of which intensity of the specified electric field (E₀, E_d) increases in the first area (R_d) near the anode grid and/or reduces in the second area (R₀) at the distance from the anode grid.

EFFECT: increased accuracy of registration of falling high-energy photons.
