Abstract: A multilayer Laue lens (MLL) that can be operated over a large range of wavelengths which is achieved by providing a lens blank comprising a substrate element extending in a plane defined by orthogonal axes x, y, z, with a layered structure deposited on the upper surface with at least two different materials that are layered upon one another in an alternating manner, wherein the y-extension of the layered structure is constant along the x-axis and varies along the z-axis within a ramp section where the y-extension of the layered structure increases from a starting point, where first particles of material of the layered structure are deposited on the upper surface of the substrate element, to a saturation point, where a maximum y-extension of the layered structure is reached; and slicing a lens out of the lens blank.

Abstract: The invention relates to a device and a system comprising the device for bunching of sample particles. The device comprises a body, a fluid channel extending through the body, an acoustic wave guide embedded in the body, and an acoustic wave condenser embedded in the body. The fluid channel forms a fluid path the body, such that the fluid channel is configured to guide a flow of a sample fluid, in which sample particles are distributed, through the fluid channel along the fluid path. The wave guide is configured to guide an acoustic reference wave to an application region of the fluid channel. The wave condenser is configured to generate a standing acoustic wave in the application region from the reference wave for bunching the particles.

Abstract: An asymmetric-cut multilayer diffracts EUV light. A multilayer cut at an angle has the same properties as a blazed grating, and has been demonstrated to have near-perfect performance. Instead of having to nano-fabricate a grating structure with imperfections no greater than several tens of nanometers, a thick multilayer is grown on a substrate and then cut at an inclined angle using coarse and inexpensive methods. Effective grating periods can be produced this way that are 10 to 100 times smaller than those produced today, and the diffraction efficiency of these asymmetric multilayers is higher than conventional gratings. Besides their ease of manufacture, the use of an asymmetric multilayer as a spectral purity filter does not require that the design of an EUV optical system be modified in any way, unlike the proposed use of blazed gratings for such systems.

Abstract: A system for x-ray imaging of a small sample comprising positioning a tamper so that it is operatively connected to the sample, directing short intense x-ray pulses onto the tamper and the sample, and detecting an image from the sample. The tamper delays the explosive motion of the sample during irradiation by the short intense x-ray pulses, thereby extending the time to obtain an x-ray image of the original structure of the sample.

Abstract: A track assembly for a skid steer type wheeled vehicle comprises a series of identical track segments, with each of the segments having a wheel or tire retaining flange depending from opposite ends thereof. Each flange has a pair of connecting lugs or tongues extending in one direction (e.g., in the direction of travel), with a single connecting lug extending in the opposite direction. Each lug or tongue pair is positioned to sandwich an opposing single lug or tongue therebetween from an adjacent track segment. Thus, each of the segments connects directly to another identical segment, with no intermediate connecting links being required. The interconnecting lugs or tongues extend straight from their respective flanges with no lateral offset, thus precluding any bending loads upon the lugs and producing a pure shear force across each connecting bolt or pin. The lugs or tongues are preferably hardened for greater durability, with the assembly including bushings for greater bearing area.

Abstract: A light splitter device adapted for use in a light-sensitive sorting machine comprising a multiplicity of optical fibers adjacent ends of which extend from a common surface, the opposite ends of the fibers being disposed in a plurality of separate groups of fibers which are respectively adapted to illuminate different light sensors, the fibers of each group respectively extending from regions distributed substantially uniformly throughout the said common surface.

Abstract: A closed loop coolant circuit for a helium cooled high temperature reactor. The circuit has a conventional purification by-pass loop including an oxidizing bed for impurities and an absorption bed for the oxidized impurities. A recycle pipe line is provided whereby a fraction of wet gas leaving the oxidizing bed is returned to the main coolant circuit.
