Abstract

In this work, we consider the scheme and determine the parameters of a multipulse X-ray source for obtaining images of the compressed state of a primary laser thermonuclear target. As an example of a source, the characteristic radiation of an iron secondary target with focusing on it of several picosecond laser pulses of subrelativistic intensity is considered. The proposed method makes it possible, based on the results of X-ray diffraction of a compressed thermonuclear target, to establish the relative large-scale inhomogeneity of the energy release of laser beams that irradiated the thermonuclear target and to estimate the decrease in the neutron yield caused by the asymmetry of the compressed target.
