Publication number: 20220397455Abstract: Spectrometer device (100) with entrance aperture (2), diffraction grating (3), two detectors (5a, 5b) to spectrally measuring the incoming light (L), the detectors being located on the same side of the dispersion plane. Two vertically focusing mirrors (4, 4a, 4b) focus the light onto detectors, the minors being arranged as front row mirrors (4b) and back row minors (4a) along two polygon graphs (6a, 6b) offset to each other and to the focal curve. The angles of deflection (cp, 91) for the front row mirrors are <90°, allowing to minimize the offset (dl) of the front row minors (4b) to the focal curve. The distances (d) between the front row minors and corresponding detectors (5b) is minimized while still avoiding collisions between the detectors (5b) and their mounts with back row detectors (5a) and their mounts. The front row mirror elements are overlapping the adjacent back row mirror element.Type: ApplicationFiled: November 6, 2020Publication date: December 15, 2022Inventors: Heinz Jürgen Graf, Rainer Simons

Patent number: 11031745Abstract: An X-ray laser has a target anode of a crystalline material that emits X-ray radiation in response to excitation and that is located on a thermally conductive substrate. An X-ray source provides an input X-ray beam that illuminates a predetermined volume of the target anode at a predefined angle relative to a surface of the anode so as to induce a Borrmann mode standing wave in the predetermined volume. An electron source outputs an electron beam that is incident on the Borrmann mode region so as to cause electron impact ionization of the crystalline material and thereby induce stimulated emission of a coherent output X-ray beam.Type: GrantFiled: January 20, 2020Date of Patent: June 8, 2021Inventors: Roger D. Durst, Juergen Graf, Christoph Ollinger
