FLUID INJECTOR FOR X-RAY TUBES AND METHOD TO PROVIDE A LIQUID ANODE BY LIQUID METAL INJECTION

摘要

Fluid injector for x-ray tubes and method to provide a liquid anode by liquid metal injection The present invention relates to a fluid injector (1) for x-ray tubes and a method to provide a liquid anode (8) by liquid metal injection, with a device (2) to inject fluid from an opening (4) in a chamber (3) of the device (2) in form of a fluid jet generated by an arrangement (5) to change the volume within the chamber (3), and comprising a reservoir (6) to store the anode material, which is fluidically connected by a pipe (7) with the chamber (3) of the device (2). The pipe (7) comprises a part (9) formed in fluid flow direction with a shape to block fluid flow from the chamber (3) to the reservoir (6) during injection. The method comprises a step injection of fluid in the direction towards an electron beam (15) and a step refilling the chamber (3) with liquid metal from the reservoir (6).
