Claim 11:
12. A method for generating X-ray radiation, the method comprising:
providing an electron beam;
providing a liquid target moving along a flow axis by ejecting a liquid through a nozzle, the liquid target comprising a non-circular cross section in a plane perpendicular 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, wherein the second width is at least 150 μm, and wherein the liquid target comprises an impact portion being intersected by the first axis;
directing the electron beam towards the impact portion as a line focus having an aspect ratio of at least 6 such that the electron beam interacts with the liquid target within the impact portion to generate X-ray radiation; and
moving a location, within the impact portion, in which the electron beam interacts with the liquid target;
wherein the liquid is ejected through the nozzle at a pressure of at least 50 bar.
