摘要： A high strength carbon fiber composite (CFC) wafer, and method of making such wafer, with low surface roughness comprising at least one sheet of CFC including carbon fibers embedded in a matrix. The wafer can have a thickness of between 10-500 micrometers. The wafer can have a root mean square surface roughness Rq, on at least one side, of less than 300 nm in an area of 100 micrometers by 100 micrometers and less than 500 nm along a line of 2 millimeter length. The wafer may be cut to form x-ray window support structures, MEMS, or other micrometer sized structures.

摘要： An x-ray device utilizes a band of material to exchange charge through tribocharging within a chamber maintained at low fluid pressure. The charge is utilized to generate x-rays within the housing, which may pass through a window of the housing. Various contact rods may be used as part of the tribocharging process.

摘要： A radiation detector assembly and a method for using the same are provided. The radiation detector assembly includes an aperture, a window covering the aperture, the window is configured to permit radiation to pass through, the window is configured to prevent the passage of fluids and particles through the aperture, and a protective device covers the window. The protective device includes a plurality of holes at least partially aligned with the aperture, is configured to permit at least some radiation to pass through the holes, is configured to prevent objects larger than the holes to contact the window and is configured to withstand external forces and prevent those forces from damaging the window.

摘要： A support structure (10) for an x-ray window comprising a support frame (11) defining a perimeter (11p) and an aperture (11a), a plurality of ribs (12) extending across the aperture of the support frame and carried by the support frame, and openings 13) between the plurality of ribs. A rib taper region (12t) can extend from a central portion (12c) of the ribs to the support frame. The taper region can include a non-circular, arcuate pair of fillets (fig. 3,(33a), (33b)) on opposing sides of the ribs and an increasing of rib width from the central portion to the support frame.

摘要： The disclosed subject matter includes devices and methods relating to anode assemblies and/or X-ray assemblies. In some aspects, a method of forming an X-ray assembly may include providing an anode base 74 formed of a first material and including a first end. The method may include depositing a second material different from the first material over a first surface of the anode base to form a coated portion 180 of the anode base. The coated portion may be configured such that some backscattered electrons do not travel beyond the coated portion.

摘要： An X-ray window comprises a primary (22) and a secondary window element (72, 74, 76). In order to evaporate debris by ohmic heating, current flows through the secondary (upstream) window element. Meanwhile, electric charge originating from electron irradiation and/or depositing charged particles is to be drained off the secondary window element via a charge-drain layer (76). To prevent large debris particles from short-circuiting the secondary window element, the current for heating the window element flows through heating circuitry (72) which is electrically insulated from the charge- drain layer.

A transmission type target (9) includes a target layer (42), a carbon-containing region (45) including sp2 bonds, and a diamond substrate (41, 46) that supports the target layer. The carbon-containing region is positioned between the target layer and the diamond substrate.
