KOMPAKTE QUELLE MIT ERZEUGUNG VON IONISIERENDEN STRAHLEN, ANORDNUNG MIT EINER VIELZAHL VON QUELLEN UND VERFAHREN ZUR HERSTELLUNG DER QUELLE

摘要

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 ionising ray-generating source comprises: · a vacuum chamber (12), · a cathode (14) capable of emitting an electron beam (18) in the vacuum chamber (12), · an anode (16) receiving the electron beam (18) and comprising a target (20) capable of generating an ionising radiation (22) from the energy received from the electron beam (18), and · an electrode (24) arranged in the vicinity of the cathode (14) and forming a Wehnelt electrode. According to the invention, the electrode (24) is composed of a conductive surface adhering to a concave face (26) of a dielectric material.
