Abstract: An X-ray imaging apparatus is disclosed. The apparatus includes a radiator housing, an X-ray tube, a source of X-rays and at least one filtration material disposed on the X-ray tube. The X-ray tube is rotatable about a longitudinal axis and is disposed at least partially within the radiator housing. The source of X-rays emits at least one X-ray beam at least partially through the X-ray tube. The X-ray beam exits the X-ray tube at an annular X-ray window. The filtration material at least partially covers a portion of the annular X-ray window. Rotation of the X-ray tube causes the X-ray beam to pass through a plurality of locations in the annular X-ray window and at least a portion of the X-ray beam is filtered by the filtration material.

Abstract: A radiation window device to transmit radiation as part of an x-ray source or detector includes a support to be subject to a substantial vacuum, and an opening configured to transmit radiation. A film is mounted directly on the support across the opening, and has a material and a thickness selected to transmit soft x-rays. An adhesive directly adheres the film to the support. A coating covers exposed portions of at least one of the evacuated or ambient sides of the film, and covers a portion of the support surrounding the film. The support, film and adhesive form a vacuum tight assembly capable of maintaining the substantial vacuum when one side is subject to the substantial vacuum. In addition, the vacuum tight assembly can withstand a temperature of greater than approximately 250 degrees Celsius.

Abstract: An X-ray window having a diamond X-ray transparent film, diamond reinforcing crosspieces and a substrate on which the diamond X-ray transparent film has been grown. As reinforcing crosspieces are made of diamond, no thermal stress is generated between the X-ray transparent film and the crosspieces. This mask excels in flatness, transmittance of X-rays, and strength.

Abstract: An anode of an X-ray tube, particularly for X-ray analysis, comprises at least two successive layers (7, 8 or 11, 10 or 13, 12) of anode material. A first layer (7, 11, 12) thereof consists mainly of an element having a comparatively low atomic number, such as scandium or chromium, while a second layer (8, 10, 13) consists mainly of an element having a comparatively high atomic number, such as molybdenum, tungsten or uranium. For the selection of a desired radiation spectrum, the tube voltage is selectively adjusted such that either or both layers are activated.

Abstract: The x-ray windows herein can have low gas permeability, low outgassing, high strength, low visible and infrared light transmission, high x-ray flux, low atomic number materials, corrosion resistance, high reliability, and low-cost. The x-ray window can include a film 11 with a polymer layer 22 and a graphite layer 21. The film 11 can consist essentially of graphite and polymer. Most of the film 11 can be the graphite layer 21. The polymer layer 22 can be a small portion of the film 11.
