X-ray dosimetric characteristics of CdIn2S4⟨Cu⟩ single crystals

The effect of doping CdIn2S4 single crystals by copper (3 mol %) on their X-ray dosimetric characteristics is investigated. It is found that the characteristic X-ray conductivity of CdIn(2)S(4)aOE (c) Cu > single crystals increases 3-16 times compared with undoped CdIn2S4 at effective radiation hardness V (a) = 25-50 keV and dose rate E = 0.75-78.05 R/min. Moreover, the persistence of the crystal characteristics completely disappears and the supply voltage of a CdIn(2)S(4)aOE (c) Cu > X-ray detector decreases fivefold. The dependence of the steady X-ray-induced current in CdIn(2)S(4)aOE (c) Cu > on the X-ray dose is described as Delta I (E, 0) ae E (alpha), where 0.6 a parts per thousand currency sign alpha a parts per thousand currency sign 1.8.
