Abstract: The invention relates to a fluorescence radiation source in which an anode which encloses a member is struck by electrons on its side which faces the member and in which the primary X-ray radiation generated in the anode generates fluorescence radiation in the member. The member is preferably arranged within an enclosing shield which keeps scattered electrons remote from the member.

Abstract: A target assembly for an electron linear accelerator (LINAC), comprising a target for converting electron beams of different energies into x-ray beams. The target has a variable thickness which can be set to a predetermined value by adjustment means. In a preferred embodiment, the target is provided with a chamber defined by two parallel plates and a bellows connecting both plates. The chamber is filled with a liquid medium of a high atomic number, such as mercury. In operation the medium is pumped through the chamber, and cooled down in a heat exchanger.

Abstract: The invention relates to a .gamma.-ray irradiation head for panoramic irradiation comprising a tungsten target revolving about an axis, and means for deflecting electrons around the same axis for producing photons in several directions either successively or simultaneously. When the beam of electrons is deflected in its entirety and when the impact zone moves on the target about the axis, the axis of the radiation lobe moves in the same way and permits irradiation according to a variable azimuth.

Abstract: A method for increasing the electron beam density and power of X-ray tubes, and a novel X-ray tube construction, wherein the target is in the form of an elongated member of target material, such as a strip, tape or filament, which is mechanically moved across the path of the electron beam to continuously present cold target material to the beam and remove heated target material from the electron beam path for cooling at a location spaced therefrom.
