A system for generating X-ray beams from a liquid target includes a vacuum chamber, a diamond window assembly, an electron source, a target material flow system, and an X-ray detector/imager. An electron beam from the electron source travels through the diamond window assembly and into a dynamic target material of the flow system. Preferably, the dynamic target material is lead bismuth eutectic in a liquid state. Upon colliding with the dynamic target material, X-rays are generated. The generated X-rays exit through an X-ray exit window to be captured by the X-ray detector/imager. Since the dynamic target material is constantly in fluid motion within a pipeline of the flow system, the electron beam always has a new target area which is at a controlled operational temperature and thus, prevents overheating issues. By providing a small focus area for the electron beams, the overall imaging resolution of the X-rays is also improved.
