SAMPLE ROTATION SYSTEM AND METHOD
The present disclosure provides a sample rotation system and method. The sample rotation system includes a rotation device, and the rotation device includes: a first carrier connected to a sample; a drive portion connected to the first carrier, wherein the drive portion is configured to drive the first carrier to rotate; and the first carrier drives the sample to rotate from an initial position to a target position; an acquisition device, configured to acquire a rotation state of the sample; and a control unit, electrically connected to the drive portion, and configured to control operation of the drive portion.
Inline x-ray measurement apparatus and method
An x-ray inspection apparatus may comprise an x-ray source, an x-ray detector, and a drive assembly. The drive assembly may be configured to lift a part carrier such that the part carrier is disengaged from a feed assembly and an object mounted on the part carrier is positioned between the x-ray source and the x-ray detector. The feed assembly may be configured to feed part carriers into and out of the x-ray inspection apparatus. The drive assembly may be further configured to subsequently lower the part carrier such that the part carrier is reengaged with the feed assembly.
CUSTOMIZABLE AXES OF ROTATION FOR INDUSTRIAL RADIOGRAPHY SYSTEMS
Described herein are examples of industrial radiography systems that enable rotation of a part about a custom axis that is offset from an actual rotation axis of a rotatable fixture that retains the part. This may be valuable in situations where it is difficult, impractical, and/or impossible to align the center of the part with the center of the rotatable fixture. In some examples, the custom axis rotation may be implemented on existing radiography machines, without requiring physical alteration of the radiography machines, integration of new components into the radiography machines, and/or risk of instability to the part and/or radiography machines.
X-ray fluorescence spectrometer and control method for x-ray fluorescence spectrometer
Provided are an X-ray fluorescence spectrometer and a control method for an X-ray fluorescence spectrometer which are capable of preventing deterioration and breakage of a sample, and contamination of an inside of an apparatus even when an abnormality occurs in the X-ray fluorescence spectrometer. The X-ray fluorescence spectrometer includes: a measuring unit including: a moving mechanism configured to move a sample between a standby position and a measurement position; an X-ray source; a detector; and a first control unit; and an information processing unit including: an analysis unit; and a second control unit configured to control the measuring unit by communicating with the first control unit, the first control unit including retreat controller configured to perform retreat control for causing the moving mechanism to retreat the sample present at the measurement position to the standby position when communication between the first control unit and the second control unit is interrupted.
DEVICE FOR HOSTING A PROBE SOLUTION OF MOLECULES IN A PLURALITY OF INDEPENDENT CELLS
A device to host a crystallization medium, such as a solution, for crystal growth and a system for X-ray diffraction experiments to determine the atomic structure of crystals. A plurality of cells have a well, a sample holder placed in the well. The solution is hosted in the sample holder between thin-plates or one thin-plate. A cap seals an opening to the cell and each sample holder can be extracted independently from each well. A system for automated X-ray diffraction experiments for small crystals in the sample holder extracted from the wells utilizes an ultrasonic acoustic levitator to determine the crystal structure at atomic resolution. X-ray diffraction images are generated by scanning the X-ray beam over the levitated sample holder along a spiral trajectory by rotating the sample holder and moving in the direction perpendicular to the X-ray beam and the rotation axis at the same time.

METHOD AND MEASURING DEVICE FOR MEASURING OBJECTS BY MEANS OF X-RAY FLUORESCENCE
A measurement object is placed on a region of a measuring table, and an overview image of the region of the measuring table is captured by an optical device. A type of the measurement object is determined from the overview image or from an identifier on the measurement object or an identifier positioned adjacently thereto. The position and/or the alignment of the measurement object on the measurement table is determined from the overview image. At least one measurement location of the measurement object is positioned in a measurement point of an X-ray fluorescence device and at least one measured value is determined from the at least one measurement location of the measurement object. The at least one measured value is compared with a setpoint value stored in a data processing device and a measurement result for the at least one measurement location of the measurement object is output.
