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: 11756760Abstract: An X-ray tube has a cathode housing having a radiation exit window, a cooled anode, a hot cathode, an insulation body, a supply line for coolant to the anode and a discharge line for coolant from the anode. The supply and discharge lines have a plurality of turns in the insulation body. The potted body has an inner and outer mold. The anode, the cathode housing and the potted body are fastened on the ceramic body. At least one plastic directing body aligns the hoses separated from the outer and inner mold. The potting space is filled with a plastic potting compound in a cured state so that the intermediate spaces between the turns on the one hand and the outer mold and the inner mold on the other hand are occupied by the plastic of the at least one directing body and/or the plastic of the potting compound.Type: GrantFiled: August 17, 2022Date of Patent: September 12, 2023Assignee: incoatec GmbHInventors: Torben Schulz, Karl Hans, Jenss Schmidt-May, Moritz Schlie

Patent number: 9728369Abstract: A high voltage vacuum feed through (23) for an electron tube (25) has an anode (28) and an insulating body (1) of ceramic material, the insulating body (1) having a continuous hollow space (10). The anode (28) has a rear part (2) and a front part (3) mounted thereto. The rear part (2) consists of a first metallic material, having a thermal expansion coefficient corresponding to a thermal expansion coefficient of the ceramic material. The rear part (2) is arranged in the hollow space (10) of the insulating body (1) and is soldered into the insulating body (1) in a vacuum-tight fashion. The front part (3) has a second metallic material whose heat conductivity is larger than that of the first metallic material. The high voltage vacuum feed through reliably remains vacuum-tight during operation and can be easily provided with different target materials.Type: GrantFiled: April 23, 2015Date of Patent: August 8, 2017Assignee: incoatec GmbHInventor: Karl Hans

Patent number: 9279776Abstract: An X-ray analysis apparatus has at least one X-ray aperture (4; 4a, 4b) which delimits an X-ray beam (RS) emitted by an X-ray source (2). The at least one X-ray aperture (4; 4a, 4b) is disposed at a separation from the sample (5) and has a single crystal aperture body (8) with a through pinhole (9). The single crystal aperture body (8) forms a peripheral continuous edge (10) which delimits the X-ray beam (RS) and starting from which the pinhole (9) widens like a funnel in a direction of an outlet opening (11) of the X-ray aperture (4; 4a, 4b) in a first area (B1). The X-ray analysis apparatus reduces impairment of X-ray measurements due to parasitic scattered radiation and at little expense.Type: GrantFiled: May 16, 2013Date of Patent: March 8, 2016Assignee: incoatec GmbHInventors: Andreas Kleine, Josef Kreith, Frank Hertlein

Patent number: 7242746Abstract: A method for manufacturing a reflector (5) for X-ray radiation (2, 3, 10, 11) which is curved in a non-circular arc shape, along a first cross-section (13) in a plane (XZ) which contains a x-direction, wherein the reflector (5) is also curved along a second cross-section (14) in a plane (YZ) which is perpendicular to the x-direction, is characterized in that the reflector (5) has a curvature along the second cross-section (14) which also differs from the shape of a circular arc. This makes the design of X-ray mirrors and the beam profile of reflected X-ray radiation more flexible, facilitates production of X-ray mirrors and at the same time provides high reflection capacity and good focusing properties for X-ray mirrors.Type: GrantFiled: December 1, 2005Date of Patent: July 10, 2007Assignee: Incoatec GmbHInventors: Carsten Michaelsen, Michael Dahms
