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.

In one embodiment, an X-ray source includes a source target configured to generate X-rays when impacted by an electron beam. The source target includes one or more thermally conductive layers; and one or more X-ray generating layers interleaved with the thermally conductive layers, wherein at least one X-ray generating layer comprises regions of X-ray generating material separated by thermally conductive material within the respective X-ray generating layer.

An x-ray source can include an x-ray tube, and a heat sink for removal of heat from the x-ray tube. The heat sink can be thermally coupled to the anode and can extend away from the anode along a heat sink longitudinal axis. The heat sink can have a base and a fin extending from the base. The base can have a greater thickness nearer the anode, and a reduced thickness along the heat sink longitudinal axis to a smaller thickness farther from the anode.

Provided is an X-ray tube, including: an electron-beam emitting unit; a target having a first surface and a second surface; a solid heat diffusion member fixed onto the second surface of the target; and a flow-path forming member, which is arranged on a side of the solid heat diffusion member, the side being opposite to the target, and that is configured to define a film flow path in which a cooling fluid forms a film flow that is parallel to a surface shape of the solid heat diffusion member. A protruding portion protrudes toward the side of the solid heat diffusion member, which is opposite to the target. The film flow path has a shape extending along at least a part of a surface of the protruding portion.

An electron collector for an x-ray tube having an electron collector base and an electron collector insert. The electron collector insert may be composed of a thermally enhanced material and is used to mitigate thermal stress from the electron collector. The electron collector insert may further prevent cracking and thermal fatigue of the electron collector.
