Abstract (en)
[origin: WO2019011997A1] The invention relates to a source generating ionising rays, and in particular X-rays, an assembly comprising a plurality of sources and a method for producing the source. The source comprises: · a vacuum chamber (12), · a cathode capable of emitting an electron beam (18) in the vacuum chamber (12), the electron beam (18) developing around an axis (19), and · an anode (76) receiving the electron beam (18) and comprising a target (20) capable of generating ionising radiation (22) from the energy received from the electron beam (18), the ionising radiation (22) being generated towards the outside of the vacuum chamber (12); wherein the anode (76) comprises a cavity (80) in which the electron beam (18) is intended to penetrate to reach the target (20), and the walls (88, 90) of the cavity (80) form a Faraday cage surrounding parasitic ions (91) that can be emitted by the target (20) inside the vacuum chamber (12); at least one getter (92), separate from the walls (88, 90) of the cavity (80) and intended to trap the parasitic ions (91), is arranged in the cavity (80).
