Abstract: The present inventive concept relates to an X-ray source comprising: a liquid target source configured to provide a liquid target moving along a flow axis; an electron source configured to provide an electron beam; and a liquid target shaper configured to shape the liquid target to comprise a non-circular cross section with respect to the flow axis, wherein the non-circular cross section has a first width along a first axis and a second width along a second axis, wherein the first width is shorter than the second width, and wherein the liquid target comprises an impact portion being intersected by the first axis; wherein the x-ray source is configured to direct the electron beam towards the impact portion such that the electron beam interacts with the liquid target within the impact portion to generate X-ray radiation.
