Open reflective target microfocus x-ray tube

Abstract

An open micro-focus X-ray tube that can emit micro-focus X-rays with high voltage and high current, the maximum tube current can reach 3mA, and the maximum tube voltage can reach 225KV, which improves the energy of X-rays and can detect thicker objects components. The unique reflective target cooling device ensures that the X-ray tube can work continuously and has a good cooling effect. The two U-shaped water inlet and outlet channels in the target sleeve communicate with the two V-shaped water inlet and outlet channels on the water sealing block respectively. There is a long column in the middle of the water sealing block, and the long column is inserted into the blind hole on the back of the target body. Divide the target body into two spaces, the water inlet chamber and the water outlet chamber. These two water inlet and outlet chambers are respectively connected to the V-shaped water inlet and outlet channels. There is only a 2mm gap between the long column on the water sealing block and the bottom surface of the blind hole of the target body. , form a narrow slit, water passes through the narrow slit, and the water flow at a certain flow rate becomes faster when it passes through this place, and the heat on the target body is quickly taken out, thereby prolonging the life of the reflective target.

Description

technical field [0001] The invention relates to a micro-focus X-ray tube used in non-destructive testing, in particular to an open reflective target that can emit high-voltage and high-current X-rays, can be equipped with a cooling device, and can detect thicker components to be tested. Microfocus X-ray tube. Background technique [0002] The transmission target of the open transmission target micro-focus X-ray tube is very thin, only 0.3mm thick, and the heat dissipation effect is poor. Therefore, the ray energy generated by the transmission X-ray tube should not be too large. When the tube voltage increases or the tube current increases, the life of the transmission target will be greatly reduced, and the heat generated by X-rays may even easily break down the transmission target. Contents of the invention [0003] Aiming at the deficiencies of the existing micro-focus X-ray tube with open transmission target, the invention provides an open reflection target micro-focus...

[0002] The transmission target of the open transmission target micro-focus X-ray tube is very thin, only 0.3mm thick, and the heat dissipation effect is poor

Therefore, the ray energy generated by the transmission X-ray tube should not be too large. When the tube voltage increases or the tube current increases, the life of the transmission target will be greatly reduced, and the heat generated by X-rays may even easily break down the transmission target.
