X-ray tube with a catching device for backscattered electrons, and operating method therefor

An x-ray tube has a cathode and a anode, and a catching device that captures backscattered electrons from the anode in the operating state of the x-ray tube. The catching device minimizes unwanted energy generation by the backscattered electrons in the catching device and the anode while maintaining...

More Information
Summary:An x-ray tube has a cathode and a anode, and a catching device that captures backscattered electrons from the anode in the operating state of the x-ray tube. The catching device minimizes unwanted energy generation by the backscattered electrons in the catching device and the anode while maintaining a high quality of the focus by the catching device being electrically insulated with respect to the anode and the cathode and being placed at an electrical potential having a value between the value of the electrical potential of the anode and the value of the electrical potential of the cathode, and the amount of the difference between the potential of the catching device and the potential of the anode is in the range from 1% to 40% of the amount of the difference between the potential of the cathode and the potential of the anode.
