The method and system for generating x-ray radiation in electron-impact x-ray sources

摘要

A method for generating x-ray radiation, comprising the steps of forming a target jet by urging a liquid substance under pressure through an outlet opening, the target jet propagating through an area of interaction; and directing at least one electron beam onto the target jet in the area of interaction such that the electron beam interacts with the target jet to generate x-ray radiation; wherein the full width at half maximum of the electron beam in the transverse direction of the target jet is about 50% or less of the target jet transverse dimension. A system for carrying out the method is also disclosed.
