Claim:
1. A convergent X-ray beam-generating device, comprising: an electron disperser element for dispersing an electron beam from an electron source, one or more magnetic and/or electric lenses for expanding and redirecting the electron beam, an anode cap made of a material and thickness, and having a cone shape and a focal point such that an X-ray radiation is generated on the entire surface of said anode cap, wherein the X-ray radiation is emitted forward, focusing mainly at the focal point of the anode cap, and a coaxial poli-collimator having the same shape as that of the anode cap, with multiple holes for collimating and focusing the X-ray radiation at the focal point of the anode cap.
