Abstract
We investigate the effect of temperature gradient on the intensity of X-ray radiation reflected from different atomic planes of a KDP crystal, depending on the crystal thickness. We have studied the phenomenon of transfer of the X-ray beam intensity for x- and z-cuts of the KDP crystal in the presence and in the absence of temperature gradient. It is shown that the intensities of reflected radiations do not saturate because in conditions of the experiment the further increase in temperature gradient leads to destruction of the sample. It is revealed that in some cases at small values of temperature gradient the intensity of reflected radiation decreases initially by more than 10%, then increases monotonically with the increase in temperature gradient.
