Abstract

An X-ray source (100) and a corresponding method for generating X-ray radiation are disclosed. The X-ray source comprises a target generator (110), an electron source (120) and a shield (140). The target generator is adapted to form a liquid jet (112) propagating through an interaction region (I), whereas the electron source is adapted to provide an electron beam (122) directed towards the interaction region such that the electron beam interacts with the liquid jet to generate X-ray radiation (124). The shield is adapted to be arranged at a distance downstream the interaction region. Preferably, the shield is arranged at a distance corresponding to the location of a maximum surface temperature of the liquid jet, thereby capturing contaminants originating from the liquid jet.(Figure 2)
