Focusing powerful X-ray pulse radiation, generated by explosive electron emission, using polycarpellary Kumakhov's optics

The main difficulty of influencing the quality of X-ray imaging is a relatively large size of the X-ray source spot (1-2 mm). In pulsed x-ray tubes, operating on the basis of explosive electron emission, a decrease stains using electrostatic and magnetic focusing is difficult due to the small distances cathode - anode.
