摘要: A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

摘要: This method for manufacturing an irradiating head includes:—providing a gun emitting a primary beam of charged particles along a propagation axis, this primary beam having a spatial distribution of charged particles having a median density Dmed1 of charged particles located at a distance d1 from the propagation axis,—the design and manufacture of a sensor capable of measuring the intensity of a beam of charged particles, this sensor comprising:—an outlet face by means of which a secondary beam of charged particles results having a spatial distribution having a median density Dmed2 of charged particles, this median density Dmed2 being located at a distance d2 from the propagation axis, and—a semiconductor layer. The design of the sensor includes selecting a thickness for the semiconductor layer, wherein the distance d2 is twice as large as the distance d1.

摘要: A liquid crystal device includes: an element substrate; a counter substrate disposed opposite to the element substrate; a sealing material disposed between the element substrate and the counter substrate; and a liquid crystal layer disposed on an inner side of the sealing material and containing liquid crystal. The element substrate includes an alignment film configured to align the liquid crystal and an ion-adsorbing first adsorption film disposed in contact with the sealing material. The alignment film includes a first vapor-deposited film and a second vapor-deposited film disposed between the first vapor-deposited film and the liquid crystal layer. The second vapor-deposited film and the first adsorption film include a column of which a long axis direction intersects a thickness direction of the liquid crystal layer. A thickness of the first adsorption film is thicker than a thickness of the second vapor-deposited film.

摘要: Technology is described to uniformly apply doses of radiation to a target material. An irradiation device may comprise an enclosure configured to receive a target material and a source configured to emit primary radiation within the enclosure. The primary radiation may be configured to irradiate at least a first portion of the target material. The irradiation device may further comprise a scattering medium disposed within the enclosure. The scattering medium may be configured to produce secondary radiation through scatter interactions in response to the primary radiation, the secondary radiation configured to irradiate at least a second portion of the target material. A thickness of the scattering medium relative to the primary radiation may have a thickness of at least 3 millimeters).

摘要: Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.
