Abstract: A magneto-fluidic seal includes a shaft, a pole piece, and a plurality of sealing fluid rings located between the shaft and the pole piece. The sealing fluid rings may be defined by the shaft and/or the pole piece and contain a ferromagnetic fluid. At least one channel having a bottom is defined by either the shaft or the pole piece. A shunt is located directly adjacent to the bottom of the channel. The thickness of the shunt is based on the energy differential 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.

The detector system generally comprises a sample capable of interacting with the incident x-ray beam, a primary detector and a secondary detector. Upon interaction with a sample of the material, the incident x-ray beam is scattered into wide angle x-ray scattering (WAXS) beams and small angle x-ray scattering (SAXS) beams that are captured by the primary or secondary detectors.

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: The present disclosure describes a magnetic fluid sealing device having a shaft centered with respect to a magnetic structure and rolling element bearing, as well as a method for centering the shaft in the device. A compressible ring 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 aligns and centers the shaft with the rolling element bearing. A liquid locking material 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 multi-beam x-ray system includes an x-ray source which emits x-rays and a housing with a first part and a second part. The second part is moveable relative to the first part and includes a plurality of optics of different performance characteristics. Each optic, through the movement of the second part relative to the first part, is positioned to a working position so that the optic receives the x-rays from the x-ray source and directs the x-rays with the desired performance attributes to a desired location.

Abstract: A two-dimensional x-ray scattering camera includes a source, an optic, a detector, and a pair of collimating blocks. The source emits x-ray beams that are reflected by the optic towards a sample. The detector detects scattering from the sample, the pair of collimating blocks is positioned between the optic and the detector to collimate the beam. A bottom surface of one block is substantially parallel a top surface of the other block, and the blocks are rotatable relative to the beam about a pivot. The system forms a two-dimensional beam that is symmetric about the primary beam axis at the detector position, regardless how the beam is collimated by the collimating blocks. The system therefore eliminates smearing and can be used for anisotropic small angle scattering at high resolution and low Qmin.

Abstract: An x-ray optical device delivers an x-ray beam with variable convergence. The convergence or the divergence of the x-ray beams varies over different parts of the reflector. The device may include an adjustable aperture 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 window, a spectrum changing layer, a fiber optic bundle, a camera sensor, and a power supply. The spectrum changing layer 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.
