  • X-ray tube
    Patent number: 11183355
    Abstract: The present invention relates to an X-ray tube for X-ray analysis. The X-ray tube comprises an anode having a target surface and a cathode. The cathode comprises an emission loop. The emission loop extends around an axis that passes through the anode, and the cathode and the anode are spaced apart from one another along the axis. Electrons emitted from the cathode irradiate the target surface of the anode to produce X-rays. The X-ray tube further comprises an electron beam guide. The electron beam guide is configured to guide electrons emitted by the cathode, so as to irradiate an area of the anode. The irradiated area is enclosed by a single boundary.
