Further, an X-ray window (14) is provided in an outer radial direction orthogonal to an acting direction of the pressure from the pressurizing unit (30), and reflection type X-ray diffraction measurement can be performed through the X-ray window (14).

Disclosed is a measurement probe for measurement of elements in a mineral slurry. The probe includes a housing having an X-ray window. The housing encloses: an X-ray source positioned to emit source X-rays at the X-ray window; an X-ray detector positioned to detect X-rays from the X-ray window; and a control module. The control module is configured to: control operation of the X-ray source and the X-ray detector; process X-rays detected by the X-ray detector to generate X-ray spectra data; and process the X-ray spectra data to determine the quantity of one or more elements of interest in the mineral slurry. The measurement probe includes a probe mount adapted to couple the measurement probe to a pipe mount on a pipe carrying the mineral slurry; when the probe mount is coupled to the pipe mount, the X-ray window provides a transmission window for X-rays into a lumen of the pipe.

A device keeps an electrochemical cell under current and at operating temperature during an X-ray beam diffraction analysis of a first electrode, the cell comprising a solid electrolyte interposed between the electrodes. The device comprises: first and second interconnectors having contact faces contacting the electrodes, which allow a gas flow and exchange between the interconnectors and the electrodes. The contact face of the first interconnector allows an X-ray beam to pass to the first electrode. A thermal and atmospheric containment chamber has an inner cavity housing a stack formed from the cell between the interconnectors and a cover closing the cavity, provided with a window allowing X-rays to pass through, the first interconnector being intended to be arranged facing the cover. The contact face of each interconnector is a slotted element; slotted portions of the slotted element are uniformly arranged and form 30% to 80% of the element's surface area.

An X-ray window of an X-ray diffractometer diffraction chamber is provided. The X-ray window can include: a plurality of unidirectional carbon fiber sheets stacked one over another, wherein carbon fibers in adjacent carbon fiber sheets are disposed at an angle relative to one another; and a binding material that binds the plurality of unidirectional carbon fiber sheets together, the binding material being at least partially transparent to X-ray radiation. The X-ray window can also or alternatively include: at least one carbon fiber sheet, the X-ray window having a carbon fiber content of at least 50 wt % and a thickness between about 0.2 mm and about 5 mm to be adapted for use at a pressure greater than atmospheric pressure.

A masking apparatus surrounds a specimen and eliminates the presence of voids and gaps between a specimen and a radiation sensitive imaging surface. Voids and gaps allow radiation to become trapped or diffracted therein and lead to noise in the resulting image. A system of radiological imaging associates both a filter and a masking assembly to a specimen for an optimal radiation exposure that permeates the specimen to an imaging array there under.

An X-ray detector monitoring device capable of detecting a time when an X-ray detector is disabled due to a slow leak is provided. The X-ray detector monitoring device is provided with an X-ray detection element 32 for detecting X-ray intensity, an X-ray detector 30 having a vacuum insulation container 33 in which an X-ray introduction window 31 is formed, a cooling means 60 for cooling the X-ray detection element 32, a detection element temperature sensor 81 mounted on the X-ray detection element 32 to output detection element temperature information T.sub.t by detecting a temperature of an X-ray detection element 32, and a control unit 40 and 70 configured to calculate an output value for controlling the cooling means 60 to output the output value to the cooling means 60 so that the detection element temperature information T.sub.t becomes a preset temperature T.sub.S. The control unit 40 and 70 is configured to detect a vacuum state of the vacuum insulation container 33 based on the output value.

The radiation detection device is equipped with a sample holding unit; an irradiation unit for irradiating a sample held on the sample holding unit with radiations; a detection unit for detecting the radiations generated from the sample; an illumination unit for irradiating the sample with light; an observation unit for observing the sample; and a light transmitting plate for allowing the light from the illumination unit, with which the sample held on the sample holding unit is irradiated, to be transmitted therethrough. The light transmitting plate is disposed at a position between the sample holding unit and the irradiation unit, and has an opening portion for allowing the radiations from the irradiation unit, with which the sample is irradiated, to pass therethrough and a scattering portion for scattering light.

Described are apparatus and methods of operation for three dimensional fluence modulation and scatter shielding for dedicated computed tomography (CT). Through the disclosed invention, the number of incident photons on the field of view (FOV) of the imaging system becomes proportional to the path length of the photon through the anatomy of interest. The apparatus is comprises a patient specific x-ray fluence modulation unit and a scatter shield unit. The fluence modulation unit reduces radiation dose differences across the anatomical part and the dynamic range requirements for the x-ray detector. The scatter shield unit is intended for preventing the scattered beams from reaching the x-ray detector. The internal structures of each unit are composed of elements with adjustable positions dependent on the specific shape of the object in the field-of-view (FOV). Method of operation are also provided.
