Abstract: An x-ray optical device (10) delivers an x-ray beam (24, 26) with variable convergence. The convergence or the divergence of the x-ray beams varies over different parts of the reflector (14). The device may include an adjustable aperture (16, 18, 21) to further select the convergence or divergence. The adjustable aperture selects the convergence angle by selectively occluding a portion of the x-ray beams.

Abstract: The system includes a conductive radiation enterance window, a spectrum changing layer, a fiber optic bundle, a camera sensor, and a power supply. The spectrum changing layer such as a scintillator is excited by the x-rays and emits a different wavelength of light, such as visible light. The fiber optic bundle receives the visible light from the spectrum changing material and transmits the visible light to the camera sensor. The camera sensor detects the light emitted from the spectrum changing layer and converts the information to electronic signals. The camera sensor is cooled by a cooling device, as such thermal conduction may cool the fiber optic bundle. To avoid condensation, current may flow through the conductive window thereby heating the conductive window.

Abstract: The present disclosure describes a magnetic fluid sealing device (10) having a shaft (20) centered with respect to a magnetic structure (35) and rolling element bearing (50), as well as a method for centering the shaft in the device. A compressible ring (70) located in a groove on the shaft is used to partially fill the gap between the shaft and the rolling element bearing and to make contact with the rolling element bearing. The compressible ring (70) aligns and centers the shaft with the rolling element bearing (50). A liquid locking material (75) is added to the gap and hardened to couple the shaft and compressible ring to the rolling element bearing. An alternative self-alignment mechanism is also disclosed.

Abstract: A pulsed laser beam (16) engraves a groove pattern on substrate (18) of material relatively transparent to the laser beam. The grooves (20) of the pattern are filled with a filling material of different density or different electron density. The pattern of grooves filled with material of different density creates a spatial density modulation that forms the basic structure of various optical elements. By adjusting the flux density of the laser beam to exceed a material break-down threshold only in specific locations, the material ablation can be reduced to a diameter smaller than the diameter of the laser beam itself. The grooves fabricated in this manner can be filled with a deformable material under vacuum with subsequent exposure to air pressure or higher pressure. It is also possible to fill the grooves with nanoparticles of different density and secured by heat application or with a coating.

Abstract: An x-ray optical system includes a multiple corner optic assembly including an adjustable aperture assembly located in close proximity to the optic assembly. The adjustable aperture assembly enables a user to easily and effectively adjust the convergence of an incident beam of x-rays or the optic focal spot size. The adjustable aperture assembly may further enable a user to condition x-rays of one wavelength and block x-rays of another wavelength and thereby reduce the amount of background radiation exhibited from x-rays of more than one wavelength.

Abstract: A magneto-f luidic seal (10) includes a shaft (16), a pole piece, and a plurality of sealing fluid rings located between the shaft and the pole piece (30). The sealing fluid rings may be defined by the shaft and/or the pole piece and contain a ferromagnetic fluid. At least one channel (38,40) having a bottom is defined by either the shaft or the pole piece. A shunt (42) is located directly adjacent to the bottom of the channel. The thickness of the shunt is based on the energy differential (AE) in the plurality of sealing fluid rings as the fluid is displaced from one side of the sealing fluid rings to the other side of the sealing fluid rings.

Abstract: A system (10) for x-ray optical alignment. The system includes an x-ray source (12), an optic (14), a collimation element (20), and alignment sensors (22). The x-ray source generates an x-ray beam (16) that is directed by the optic at a sample (s). The collimation element is located between the optic and the sample to define the profile of the x-ray beam. The sensors receive the x-ray beam from the optic and generated signal indicative of the system alignment. The sensors may be located on a surface (24) of the collimation element facing the optic. The inner edge of the sensors may be located at equal intervals radially about the collimation element and may form an aperture (21) having a symmetric shape.
