Liquid jet target X-ray source

Abstract

An X-ray source is provided comprising a target generator configured to generate a liquid jet having an elongated cross with a major axis and a minor axis; an electron source configured to generate an electron beam arranged to interact with the liquid jet in an interaction region to generate X-ray radiation; and an X-ray transparent window arranged to transmit X-ray radiation generated in the interaction region, wherein the X-ray transparent window is located for extraction of X-ray radiation at an angle α relative to the major axis; wherein the target generator is configured to generate the liquid jet such that said jet has a thickness at the interaction region, along a propagation direction of the electron beam, that is less than an electron penetration depth of the electron beam in the liquid jet. A corresponding method for generating X-ray radiation is also provided.
