摘要： An electron beam 3D printing machine, comprising a chamber for generating and accelerating an electron beam and an operating chamber in which a metal powder is melted, with the consequent production of a three-dimensional product. The chamber for generating and accelerating an electron beam houses means for generating an electron beam and means for accelerating the generated electron beam, while the operating chamber houses at least one platform for depositing the metal powder, metal powder handling means and electron beam deflection means. The accelerator means for the generated electron beam comprise a series of resonant cavities fed with an alternating signal.

摘要： An x-ray window can include an adhesive layer sandwiched between and providing a hermetic seal between a thin film and a housing. The adhesive layer can include liquid crystal polymer. The liquid crystal polymer can be opaque, gas-tight, made of low atomic number elements, able to withstand high temperature, low outgassing, low leakage, able to relieve stress in the x-ray window thin film, capable of bonding to many different materials, or combinations thereof.

摘要： A window member for separating an internal environment of an x-ray device from an environment external to the x-ray device is provided. The window member comprises a substrate and a coating layer disposed upon a surface of the substrate. The substrate is formed from a polycrystalline material and is substantially transparent to low-energy x-rays. The coating layer is non-porous, covers the crystal grains at the surface of the substrate and extends into the grain boundaries therebetween, such that the coating layer forms an impermeable barrier between the substrate and the external environment.

摘要： An electron collector for an electromagnetic ray generating device is provided. The electron collector includes a body having a surface configured to intercept backscattered electrons produced by an electron beam striking an anode to generate electromagnetic rays. The body is operative to absorb the backscattered electrons and is formed by particles of a first material disposed within a matrix of a second material.

摘要： Methods and systems are described for processing cellulosic and lignocellulosic materials and useful intermediates and products, such as energy and fuels. For example, irradiating methods and systems are described to aid in the processing of the cellulosic and lignocellulosic materials. The electron beam accelerator has multiple windows foils and these foils are cooled with cooling gas. In one configuration a secondary foil is integral to the electron beam accelerator and in another configuration the secondary foil is part of the enclosure for the biomass conveying system.

摘要： For manufacturing a radiation window for an X-ray measurement apparatus, and etch stop layer is first produced on a polished surface of a carrier. A thin film deposition technique is used to produce a structural layer on an opposite side of said etch stop layer than said carrier. The combined structure comprising said carrier, said etch stop layer, and said structural layer is attached to a region around an opening in a support structure with said structural layer facing said support structure. The carrier is etched away.
