FIELD: physics.SUBSTANCE: method of making a through-type target of pulse-type X-ray tube involves using metal foil made from a high-atomic number metal. Elements are made on the surface of the foil, which can be stretched or compressed due to flexural deformation of the foil. In the target of the X-ray tube made of high-atomic number metal foil on the area of the surface of the foil lying in the zone of the focal spot, there are drop-forged protrusions, the height and maximum dimension in the cross-section of which do not exceed 0.2S and 0.3d, respectively, where S is the size of the gap between the cathode and the target, d is the diameter of the focal spot of the tube, wherein the distance between protrusions does not exceed 0.3d or the foil is divided into corrugated strips mounted on a substrate made from low-atomic number material; strips in the plane of the substrate lie tightly against each other; the height and spacing of the corrugations do not exceed 0.2S and 0.2d, respectively, where S is the size of the gap between the cathode and the target, d is the diameter of the focal spot of the tube; the width of the strips does not exceed 2 mm.EFFECT: reduced mechanical stress in the material of the target.3 cl, 4 dwg, 4 dwg |
