Abstract

The invention discloses an X-ray source. The X-ray source comprises an electron beam generation device, an X-ray target and a collimator, wherein the electron beam generation device is configured to emit electron beams; the X-ray target is arranged on an emission direction of the electron beams emitted by the electron beam generation device; the collimator comprises a collimation hole which is located between an emission end of the electron beam generation device and the X-ray target; the size of the collimation hole is smaller than the hole of the X-ray target; and the electron beams emittedby the electron beam generation device are irradiated on the X-ray target through the collimation hole so as to generate X-rays.

Description

technical field [0001] At least one embodiment of the present disclosure relates to an X-ray source. Background technique [0002] The accelerating tube will accelerate the electrons generated by the electron gun to a certain energy and hit the target, generate bremsstrahlung in the target, and emit X-rays; X-rays will be detected by the X-ray detector after passing through the substance to be inspected and converted into electrical signals Record; the X-ray detection image of the inspected object can be obtained by X-ray point, line scanning or surface irradiation, among which, the image fineness and spatial resolution are an important index to measure the quality of the X-ray detection image; the factors affecting this index There are many factors, among which the geometric size of the source image that generates X-rays is one of the key factors. [0003] In a conventional X-ray source, electrons are accelerated by an electromagnetic field and hit the target radiation tar...
