x-ray conversion target

Abstract

The invention discloses an X-ray converting target which comprises a base body and a target layer plate. The base body comprises a base plate and a framework, wherein at least one guide plate is fixedly arranged on the upper surface of the base plate, and the guide plate, the base plate, the framework and the target layer plate form a first coolant layer. The X-ray converting target further comprises a sealing plate. At least one second guide plate is fixedly arranged on the lower surface of the base plate, and the second guide plate, the base plate, the framework and the sealing plate form a second coolant layer. The first coolant layer comprises at least one flow inlet channel and at least one flow outlet channel. The second coolant layer comprises at least one flow inlet channel and at least one flow outlet channel. One end of each flow inlet channel is used for coolants to pass through, the other end of each flow inlet channel is communicated with the corresponding flow outlet channel, and one end of each flow outlet channel is used for the coolants to flow out. The X-ray converting target guarantees high efficiency of converting large-power or super-power electronic beams into X rays and meanwhile achieves temperature evenness. Furthermore, the service life of the converting target is prolonged.

Description

technical field [0001] The invention relates to an X-ray conversion target. Background technique [0002] Due to the advantages of X-rays in penetrability, the radiation industry has put forward an urgent need for electron beam conversion to X-rays. If the high-power 5-10MeV electron beam can be converted into X-rays, its penetration and processing capabilities will be comparable to those of Co-60γ radiation sources. This makes the existing accelerator irradiation device more applicable and enhances its operational flexibility, and can also directly replace part of the Co-60 irradiation device. [0003] However, in the process of converting electron beams into X-rays, the proportion of electron beam energy converted into X-ray energy is relatively small, and more than 80% to 90% of the energy will be released in the form of heat. In order to ensure the conversion efficiency, the thickness of the conversion target is usually relatively small, and the scanning surface of the...
