  • Electron Beam Focusing and Centering
    Publication number: 20140219424
    Abstract: A method and device for control of an electron beam flux, electron spot size, and/or electron spot location. Electromagnetic radiation from an anode of the x-ray tube can be focused on a detector. The detector can send a signal to a control module based on the electromagnetic radiation focused on the detector. The control module can control the electron beam with a beam control device and/or a current control device. The signal can also indicate anode temperature at the electron spot.

  • Small x-ray tube with electron beam control optics
    Patent number: 8761344
    Abstract: An x-ray tube comprising an anode and a cathode disposed at opposing ends of an electrically insulative cylinder. The x-ray tube includes an operating range of 15 kilovolts to 40 kilovolts between the cathode and the anode. The x-ray tube has an overall diameter, defined as a largest diameter of the x-ray tube anode, cathode, and insulative cylinder, of less than 0.6 inches. A direct line of sight exists between all points on an electron emitter at the cathode to a target at the anode.

  • RESISTIVELY HEATED SMALL PLANAR FILAMENT
    Publication number: 20120212157
    Abstract: A planar filament comprising two bonding pads and a non-linear filament connected between the two bonding pads. The planar filament may be wider in the center to increase filament life. The planar filament can form a double spiral-serpentine shape. The planar filament may be mounted on a substrate for easier handling and placement. Voltage can be used to create an electrical current through the filament, and can result in the emission of electrons from the filament. The planar filament can be utilized in an x-ray tube.
