The X-ray tube is suitable for providing in a small, easily accessible volume (120 mm<3>) a dose output of 10<4> R/s per kW of generator power. The X-ray tube consists, apart from additional components, of two annular anodes and a cathode arrangement surrounding these in the form of a circle. In the interior of the annular anodes (two frustoconical surfaces touching in a circle) there is an opening which is easily accessible from outside and into which the material to be irradiated can be inserted. The arrangement enables optimisation of the following parameters: distance between irradiation chamber and anodes, direction of emission of the X-radiation (preferably into the irradiation chamber), large anode surfaces, large cooling surfaces, high disruptive strengths through field-free space. The tube can be applied in radiology, dosimetry, fluorescence analysis, radiation biology, pharmacy, chemistry. <IMAGE>
