It is shown that when a relativistic electron beam (current 1 A) interacts with a dense plasma (np~ 1016-5xl016 cm-3), a localization of χ rays of energy ~ 15 keV is produced in the plasma formation region. The geometric dimensions of the localization do not exceed the geometric dimensions of the plasma formation and decrease with increasing plasma density. The intensity of the χ rays is found to depend on the width of the energy spectrum of the beam electrons, on the beam current, and on the plasma density.
