Patent number: 10964439Abstract: An X-ray diffraction apparatus having a solar slit, and a method for preventing the diffraction image on a detector from spreading in the in-plane direction even when an X-ray irradiation region spreads over the sample surface due to measurement by GIXD, thereby allowing for measurement with a short measurement time and a high resolution. The soller slit 100 includes a plurality of metallic thin plates 110, each being perpendicular to the bottom surface, which are arcuately arranged with a predetermined angular interval between each other so as to pass X-rays in a radiating direction from a particular focus, the soller slit being provided to be used at a position through which X-rays diffracted on a sample surface pass, the particular focus being the center of a goniometer circle, the X-rays being irradiated on a sample at an angle for GIXD.Type: GrantFiled: October 24, 2018Date of Patent: March 30, 2021Assignee: RIGAKU CORPORATIONInventors: Ladislav Pina, Adolf Inneman, Kazuhiko Omote, Shintaro Kobayashi

Patent number: 9159524Abstract: The X-ray generating apparatus 100 applies an electron beam e1 onto a target 150 to generate X-rays x1, and includes a permanent magnet lens 120 configured to focus the electron beam e1, a correction coil 130 provided on a side of the electron beam e1 with respect to the permanent magnet lens 120 and configured to correct a focus position formed by the permanent magnet lens 120 in a traveling direction of the electron beam e1, and a target 150 onto which the focused electron beam is applied. Accordingly, the apparatus configuration can be extremely compact and lightweight in comparison with general apparatuses. Furthermore, by the correction coil 130, the intensity of the magnetic field can be finely adjusted and the focus position in the traveling direction of the electron beam e1 can be finely adjusted.Type: GrantFiled: October 16, 2013Date of Patent: October 13, 2015Assignee: RIGAKU CORPORATIONInventors: Martin Horvarth, Jiri Marsik, Ladislav Pina, Vaclav Jelinek, Naohisa Osaka, Kazuhiko Omote, Makoto Kambe, Licai Jiang, Bonglea Kim

Patent number: 7127037Abstract: A Soller slit device is provided for collimation of high energy radiation, such as X-ray or EUV radiation, and has a low angle of divergence (less than 0.1°) and a high transmission efficiency (60 to 80% or greater). The Soller slit is made up of multiple, parallel blades of low-density material, such as glass, mica, or the like, which can be treated to reduce reflectivity. The Soller slit device of the invention advantageously provides an increased peak intensity and decreased peak width in diffraction patterns produced in high energy diffractometry applications, such as X-ray diffractometry.Type: GrantFiled: July 25, 2003Date of Patent: October 24, 2006Assignee: Bede Scientific Instruments Ltd.Inventors: David Keith Bowen, Ladislav Pina, Adolf Inneman, Stephan Menzer

Patent number: 6881965Abstract: The invention provides a miniaturized multi-foil object for use in a laboratory environment and other practical applications that require small or portable and/or disposable high energy radiation optics. Specifically, the invention finds utility in high energy lithographic systems, such as X-ray or EUV lithography, as a condenser optic or in topographic systems. In lithographic systems, the present invention exhibits square symmetry, a relatively large aperture size, and disposability. Additionally, the multi-foil optic of the invention provides a high throughput efficiency.Type: GrantFiled: July 28, 2003Date of Patent: April 19, 2005Assignee: Bede Scientific Instruments Ltd.Inventors: David Keith Bowen, Ladislav Pina, Adolf Inneman, Rene Hudec, Stephan Menzer

Patent number: 6782076Abstract: An X-ray topographic system comprises an X-ray generator producing a beam of X-rays impinging on a limited area of a sample such as a silicon wafer. A solid state detector is positioned to intercept the beam after transmission through or reflection from the sample. The detector has an array of pixels matching the beam area to produce a digital image of said limited area. Relative stepping motion between the X-ray generator and the sample produces a series of digital images which are combined together. In optional embodiments, an X-ray optic is interposed to produce a parallel beam to avoid image doubling, or the effect of image doubling is removed by software.Type: GrantFiled: December 7, 2001Date of Patent: August 24, 2004Assignee: Bede Scientific Instruments LimitedInventors: David Keith Bowen, Matthew Wormington, Ladislav Pina, Petra Feichtinger

Patent number: 6711234Abstract: This invention relates to a portable apparatus for carrying out X-ray fluorescence spectrometry on specimen materials at a distance from the apparatus. The apparatus comprises an X-ray generating tube, such as a microfocus tube, and two paraboloidal X-ray reflecting mirrors. The first collecting mirror is positioned in close coupled arrangement adjacent to the exit window of the tube, such that it emits parallel X-ray radiation to the second focusing mirror, which is aligned on the axis of and spaced apart from the first mirror (11). The second mirror (12) collects the parallel X-ray radiation at its end closest to the first mirror and emits X-ray radiation in a focused beam onto the specimen. The distance between the first and second mirrors is adjusted to suit the distance from the X-ray tube to the specimen. Focal spots on the specimen of diameter less than 15 microns (590.55 microinches) are possible, enabling precise analysis of small areas of the specimen.Type: GrantFiled: May 16, 2002Date of Patent: March 23, 2004Assignee: Bede Scientific Instruments LimitedInventors: Neil Loxley, David Keith Bowen, Ladislav Pina

Patent number: 5893549Abstract: Mirror support means having a metal block machined with a first pair of slots shaped to receive a first pair of curved mirrors and a second pair of slots shaped to receive a second pair of curved mirrors. The block is sufficiently resiliently deformable to enable the slots to be widened to receive the mirrors and then for the mirrors to be clamped in position, the slots being accurately machined so that the mirrors are bent into their required forms of curvature. The use of a unitary block simplifies the construction and setting up of the support means for the mirrors.Type: GrantFiled: November 27, 1996Date of Patent: April 13, 1999Assignee: Medical Research CouncilInventors: Ladislav Pina, Adolf Inneman, Ulrich Wolfgang Arndt, David Keith Bowen
