Publication number: 20240062985Abstract: An x-ray tube includes a thermionic cathode generating an electron beam propagating from the cathode to a target along a beam axis. The x-ray tube has apertures in the form of a control electrode with a first aperture opening, a focusing electrode with a second aperture opening and a beam shaping electrode with a third aperture opening. The first aperture opening is smaller than the emission surface and has a contour rotationally symmetric with respect to the beam axis. The second aperture opening is larger than the first aperture opening and has a contour rotationally symmetric with respect to the beam axis. The third aperture opening has a contour which is aligned with an xy plane and non-rotationally symmetric with respect to the beam axis. The X-ray tube has a simple structure for generating an electron beam where the number of electrons can be varied easily over a wide range.Type: ApplicationFiled: August 10, 2023Publication date: February 22, 2024Applicant: incoatec GmbHInventors: Paul Radcliffe, Christian Hoffmann, Kaan Atak, Carsten Michaelsen

Patent number: 10847336Abstract: An analytical X-ray tube with an anode target material that emits characteristic X-rays in response to excitation by an electron beam may include any of several advantageous features. The target material is deposited on a diamond substrate layer, and a metal carbide intermediate layer may be provided between the target material and substrate that provides enhanced bonding therebetween. An interface layer may also be used that provides an acoustic impedance matching between the target material and the substrate. For a low thermal conductivity target material, a heat dissipation layer of a higher thermal conductivity material may also be included between the target material and substrate to enhance thermal transfer. The target material may have a thickness that corresponds to a maximum penetration depth of the electrons of the electron beam, and the structure may be such that a predetermined temperature range is maintained at the substrate interface.Type: GrantFiled: August 17, 2017Date of Patent: November 24, 2020Inventors: Roger D.
