A device and method for obtaining x-ray point light source

Abstract

The invention belongs to the field of the application of pulse power techniques, in particular relates to a device and method for acquiring an X-ray point light source. The device comprises a pulse power device, a vacuum cavity, a cathode, an anode and a target piece, wherein the pulse power device and the vacuum cavity are connected, the cathode, the anode and the target piece are arranged in the vacuum cavity, the cathode is connected with the pulse power device, a vacuum pumping port and an emergent hole are arranged on the vacuum cavity, an X ray emitted from the target piece can pass through the emergent hole, the vacuum pumping device is connected with the vacuum pumping port, the anode is of a hollow structure, a transmission rod passes through a hollow part of the anode, one end of the transmission rod is connected with the cathode, and the other end of the transmission rod is close to the target piece. In the traditional camera technique of the pulse power device, the X-ray point light source with a diameter of dozens of micron ranges cannot be acquired; with the adoption of the device and the method, provided by the invention, the X-ray point light source with dozens of micron ranges can be acquired, and the accuracy and the sensitivity of diagnosis can be improved.

Description

technical field [0001] The invention belongs to the application field of pulse power technology, and in particular relates to a device and a method for obtaining an X-ray point light source. Background technique [0002] In the photography technology of pulse power devices, in order to obtain X-ray point light sources with a diameter of tens of microns, the method of micro-condensing electron beams with magnetic lenses is often used. Domestic and foreign laboratories adopt many technical methods and carry out a large number of research projects and funds. But so far, there has been no report of an X-ray point source with a diameter of tens of microns. Since the smaller the size of the X-ray source, the higher the accuracy and sensitivity of diagnosis, so a method of micro-focusing the X-ray source is needed to solve this problem. Contents of the invention [0003] Aiming at the deficiencies of the current existing technology, the present invention breaks through the tradi...
