Patent number: 6453006Abstract: The present invention relates to the calibration and alignment of an X-ray reflectometry (“XRR”) system for measuring thin films. An aspect of the present invention describes a method for accurately determining C0 for each sample placement and for finding the incident X-ray intensity corresponding to each pixel of a detector array and thus permitting an amplitude calibration of the reflectometer system. Another aspect of the present invention relates to a method for aligning an angle-resolved X-ray reflectometer that uses a focusing optic, which may preferably be a Johansson crystal. Another aspect of the present invention is to validate the focusing optic. Another aspect of the present invention relates to the alignment of the focusing optic with the X-ray source. Another aspect of the present invention concerns the correction of measurements errors caused by the tilt or slope of the sample.Type: GrantFiled: March 16, 2000Date of Patent: September 17, 2002Assignee: Therma-Wave, Inc.Inventors: Louis N.

Publication number: 20020094060Abstract: A method and apparatus for continuously presenting a sample from a stream of particulate material which contains crystalline substances and for effectively continuously analysing the sample by X-ray diffraction are provided. An extracted sample flow is fed onto a continuously moving carrier and its surface smoothed and flattened for X-ray diffraction patterns to be detected and analysed to provide a compositional analysis for the crystalline substances. The sample is continuously removed from the carrier prior to further sample being fed onto the carrier. The invention is particularly applicable for phase composition analysis of cement and cement clinker and provides an effectively continuous analysis substantially in real time in contrast to prior art laboratory analyses of discrete samples.Type: ApplicationFiled: December 19, 2001Publication date: July 18, 2002Inventors: Ian Charles Madsen, Nicola Vivienne Yorke Scarlett, Constantine George Manias, David James Retallack, Karl Edmund Schneider

Patent number: 6408047Abstract: The invention provides a method of performing x-ray crystallography on samples by using a robot to select the target sample, to position the sample for x-ray crystallography, and to deposit the sample, all without transferring the sample to another device, such as a goniometer. This method allows high throughput, automated crystallography, thereby providing a high volume of samples to be tested while lessening the need for human intervention.Type: GrantFiled: October 4, 2000Date of Patent: June 18, 2002Assignee: Rigaku/MSC, Inc.Inventors: Mel Kitagawa, Keith Crane, Paul N Swepston, Joseph D Ferrara

Patent number: 6400797Abstract: This present invention provides a sample changer for automatically changing from one sample to the next in support of high throughput X-ray powder diffraction data acquisition in a capillary geometry. The samples are mounted on the outer rim of a disk or turntable, with each sample having its capillary axis parallel to a radius emanating from the center of the disk on which the samples are mounted. Each sample is mounted on a separate motor shaft which permits the sample to be rotated about the longitudinal axis of the capillary during data acquisition. To change from one sample to the next, the disk or turntable is rotated about its axis thereby presenting in turn each new sample to a X-ray beam. When the data acquisition is completed for that sample, a new sample is rotated into the beam and its data collection is carried out.Type: GrantFiled: June 22, 2000Date of Patent: June 4, 2002Inventor: Kevin L. D'Amico

Patent number: 6385289Abstract: A two-dimensional position-sensitive X-ray detector is used for the precision measurement of lattice constants so that a plurality of X-ray rocking curves can be measured at the same time for the respective points on a sample and an area map, on the sample, of the lattice constants can be obtained in a short time. X-rays from an X-ray source pass through the first slit and are then incident on a crystal collimator. X-rays reflected by the crystal collimator are incident on the sample. X-rays diffracted at the sample are detected by the two-dimensional position-sensitive X-ray detector. The diffracted X-rays from the respective points on the sample are detected separately at respective points on the X-ray detector.Type: GrantFiled: April 10, 2000Date of Patent: May 7, 2002Assignee: Rigaku CorporationInventor: Tetsuo Kikuchi

Patent number: 6371640Abstract: An apparatus for characterizing a library is provided in which the library contains an array of elements and each element contains a different combination of materials. The apparatus includes an x-ray beam directed at the library, a chamber which houses the library and a beamline for directing the x-ray beam onto the library in the chamber. The chamber may include a translation stage that holds the library and that is programmable to change the position of the library relative to the x-ray beam and a controller that controls the movement of the translation stage to expose an element to the x-ray beam in order to rapidly characterize the element in the library. During the characterization, the x-ray beam scatters off of the element and a detector detects the scattered x-ray beam in order to generate characterization data for the element.Type: GrantFiled: October 3, 2000Date of Patent: April 16, 2002Assignee: Symyx Technologies, Inc.Inventors: Damian Hajduk, James Bennett, Rakesh Jain
