The invention relates to the technical field of X-ray tubes, and discloses an anode target disc for a rotary anode X-ray tube. The anode target disc for the rotary anode X-ray tube comprises an anodetarget disc, a beryllium window and a high-voltage plug, wherein a secondary target disc is arranged on one side of the anode target disc; the other side of the secondary target disc is movably sleeved in a supporting rod; the other end of the supporting rod is fixedly connected to one end of the high-voltage plug; correspondingly-arranged permanent magnets are fixedly installed on the opposite sides of the anode target disc and the secondary target disc; the magnetic poles of the opposite surfaces of the two permanent magnets are different; and the outer edge of the disc diameter of the secondary target disc is exactly located on the inner edge of the disc diameter of the anode target disc. According to the invention, the secondary target disc is arranged on one side of the anode target disc, the side edge of the secondary target disc receives part of scattered X-rays, and the X-rays of the secondary target disc are excited again by utilizing the X-rays, so that newly generated secondary X-rays are emitted, the scattered and lost X-rays are utilized, the lost X-rays are reinforced, and the emitting quality of the X-rays is improved.
Description
technical field [0001] The invention relates to the technical field of X-ray tubes, in particular to an anode target disc for a rotating anode X-ray tube. Background technique [0002] The basic structure of an X-ray tube is composed of a cathode (filament), an anode (target), a focusing system, an anode cover and a window, and they are sealed in a high-vacuum glass (ceramic) casing. Usually, the anode target disc is fixed installation, and the cooling system is used to dissipate heat from the fixed anode. Since the focal spot temperature of the fixed anode has a certain limit, overheating causes the anode to melt, so if you want to increase the power, you have to increase the focal spot to increase the heat dissipation area, resulting in a decrease in image quality. Therefore, a rotating anode has been proposed. , which can distribute the heat generated by electron bombardment in the circular area of the continuously moving target surface, reduce the temperature of the a...
