  • Patent number: 10677628
    Abstract: A method of determining a mass flow rate, volumetric flow and test weight of grain during harvesting operations. A sensor is disposed in the harvesting machine against which clean grain piles are thrown by the clean grain elevator flights. The sensor changes the direction of the clean grain pile such that each clean grain pile compresses into a substantially discrete, contiguous shape producing discrete grain forces resulting in discrete signal pulse magnitudes generated by the sensor. The mass flow rate is calculated by summing the signal magnitudes and dividing the summed magnitudes by the sampling period. The volumetric flow rate is calculated by multiplying the pulse width generated by the sensor by a multiplier which relates pulse width to volumetric flow. The test weight of the clean grain is calculated by dividing the mass flow rate by the volumetric flow rate.

    Abstract: A method for correcting erroneous intensity measurements caused by defective pixels of the detector for a single-crystal X-ray diffraction system uses collected diffraction images and a defective pixel list to modify three-dimensional reflection profiles by replacing profile elements affected by the defective pixels with corresponding profile elements from a model profile. Reflection positions on the detector are predicted using an orientation matrix for the crystal and a three-dimensional observed profile is constructed for each reflection. A model profile is constructed using normalized profile data from multiple reflection profiles. The observed profiles are compared with the defective pixel list to determine which profile elements are affected by defective pixels, and those elements are replaced by corresponding elements from the model profile.

    Abstract: Plate-like samples each having as a principal plane thereof a cross section perpendicular to the long axis direction of a polycrystalline silicon rod grown by the deposition using a chemical vapor deposition method are sampled; an X-ray diffraction measurement is performed omnidirectionally in the plane of each of the plate-like samples thus sampled; and when none of the plate-like samples has any X-ray diffraction peak with a diffraction intensity deviating from the average value ±2×standard deviation (?±2?) found for any one of the Miller indices <111>, <220>, <311> and <400>, the polycrystalline silicon rod is selected as the raw material for use in the production of single-crystalline silicon. The use of such a polycrystalline silicon raw material suppresses the local occurrence of the portions remaining unmelted, and can contribute to the stable production of single-crystalline silicon.

  • Patent number: 8605858
    Abstract: Embodiments of methods and systems for inspecting a structure for a crystallographic imperfection are provided. In the method, an X-ray wavelength that is particularly susceptible to diffraction by the crystallographic imperfection is identified. Then an X-ray source is provided to emit X-rays in the identified X-ray wavelength. While placing the structure at a sequence of positions relative to the X-ray source, X-rays are directed at the structure in multiple, non-parallel arrays to create sequential patterns of diffracted X-rays. The patterns of diffracted X-rays are digitally captured and communicated to a computer that compares them to locate the crystallographic imperfection. For a surface imperfection, the imperfection may be marked with a target to allow for physical removal.

  • Patent number: 8600004
    Abstract: An incident X-ray is emitted in a wide angular sector toward an amorphous material specimen which backscatters the X-rays. The method comprises: a step of recording experimental photon intensity measurements as a function of the angle of incidence; a step of correcting the experimental intensity, taking into account at least the absorption phenomena inside the specimen dependent on the penetration length l of the incident wave inside the specimen before reflection; a normalization step referring the corrected intensity arising from the experimental intensity to an electron intensity according to a normalization coefficient (?); a step of calculating a discretized function Q.

  • Publication number: 20130279653
    Abstract: Methods and apparatus are provided for performing back-reflection energy-dispersive X-ray diffraction (XRD). This exhibits extremely low sensitivity to the morphology of the sample under investigation. As a consequence of this insensitivity, unprepared samples can be analyzed using this method. For example, in a geological context, whole rock samples become amenable to analysis. Modifications of the technique are described to suppress fluorescence signals that would otherwise obscure the diffraction signals.

  • Patent number: 8548123
    Abstract: An area detector used in a two-dimensional system is used as a point detector in Bragg-Brentano and other geometries by providing the area detector with a mask the limits the area through which X-rays can enter the detector. Secondary X-ray optics and a monochromator that are part of the diffractometer geometry are attached to the area detector mask to allow a fast and easy switch between the two-dimensional detector mode and the point detector mode. A concave detector mask is used with a spherical detector in order to reduce the secondary beam path and increase detector efficiency and the opening in the detector mask can be offset from the mask center to achieve high 2? angle measurements. Single channel bypath electronics are used to disregard the dimensional position of each X-ray count to increase the efficiency and speed of the system.

  • Patent number: 8462913
    Abstract: A radiation detecting apparatus includes a collimator and a detector, the collimator having a material for blocking radiation and a region that is a sector of an annulus or multiple regions in a configuration in the shape of a sector of an annulus for allowing transmission of the radiation. The detector is spaced a distance from the collimator such that when a radiation source and sample crystal material are positioned at suitable positions, the radiation is collimated by the collimator and contacts the sample a predetermined distance from the detector at multiple of locations corresponding to the region or regions of the collimator. The Bragg diffracted radiation from the crystal material at two or more and preferably all of the locations overlap at the detector.

  • Patent number: 8437450
    Abstract: A method for analysis includes directing a converging beam of X-rays toward a surface of a sample having multiple single-crystal layers, including at least a first layer and a second layer that is formed over and tilted relative to the first layer. The X-rays that are diffracted from each of the first and second layers are sensed simultaneously while resolving the sensed X-rays as a function of angle so as to generate a diffraction spectrum including at least a first diffraction peak due to the first layer and a second diffraction peak due to the second layer. The diffraction spectrum is analyzed so as to identify a characteristic of at least the second layer.

  • Publication number: 20130028385
    Abstract: The invention includes an x-ray goniometer positionable directly adjacent to processing machines used in the cutting, milling, drilling and shaping of crystal boules and crystal ingots, used in conjunction with an adjustable tilt platform capable of pitch, yaw and roll movement, allowing in-situ measurement and automatic adjustment of crystal orientation with respect to the processing machine. The goniometer may be secured to the tool or a portion of the machine which is adjacent the piece to be worked. Various embodiments include an x-ray goniometer and adjustable tilt platform incorporated into a core drilling machine, saw, surface grinder, polishing apparatus, or orientation flat or notch grinder. Incorporating an x-ray goniometer and adjustable tilt platform directly into a crystal processing machine results in a decrease in overall processing time and labor, and a significant increase in precision when processing crystal ingots into a final product, such as a notched wafer.
