Abstract

The invention discloses a multi-target material X light tube, relating to the technical field of X-ray light tubes in an X fluorescence analyzer. The multi-target material X light tube comprises a shell, high pressure oil, a glass tube, a cathode, an anode target, an anode, electron beam, X-ray and an X-ray window, wherein the cathode and the anode are respectively arranged at both ends of the glass tube in which vacuum is formed; the anode target is arranged at an end face of the anode which is close to the cathode; the electron beam ejected by the cathode ejects on the anode target to form X-ray which passes through the X-ray window; the anode target consists of a plurality of small target faces; and at least one magnet and an automatic light spot locating device are arranged around theperiphery of the X-ray window. The invention aims at providing a multi-target material X light tube of which the target face consists of multiple target materials, with high target face use ratio, increased analysis range and improved service life of the target face.

Description

technical field

[0001] The invention relates to the technical field of X-ray light tubes in X-ray fluorescence analyzers. Background technique

[0002] At present, the X-ray tubes used in X-ray fluorescence analyzers are X-ray tubes with a fixed anode and a single target. The targets used include rhodium, silver, tungsten, molybdenum, palladium, chromium, gold, etc. Each target has its interference elements and measurement range, and users can only choose X-ray tubes according to their own application range.

[0003] Because the structure of the X-ray tube is complex and expensive, it is impossible for the user to store multiple light tubes with different targets to replace the X-ray tube by himself, and only one X-ray tube can be used to analyze all the elements in the sample. Therefore, if there is an X-ray tube that can switch targets, it will bring great convenience to users.

[0004] In addition, the target area in the X-ray tube is relatively large, with an area of ​...
