Abstract
An X-ray tube including an electron source and a magnetic guide. The X-ray tube includes at least one electron source, at least one microtip, and an extraction grid, one zone of which emits electrons. Further provided are at least one anode, one zone of which emits X-rays under the impact of the electrons, and a magnetic guiding device for the electrons, capable of creating a magnetic field which is homogeneous at least between the zones. Such an X-ray tube may find application to X-ray absorption analysis or X-ray fluorescence analysis.
