摘要： Linear ribs are formed radially with a center at a through-hole on one face of an X-ray transmissive film (radiolucent film) in an X-ray transmissive window (radiolucent window) to be used for an X-ray detector (radiation detector). The X-ray transmissive window faces a sample. A beam for irradiation to the sample passes through the through-hole, and X-rays (radiation) are radially emitted on a line extending through the through-hole and enter the X-ray transmissive window. Since the linear ribs are formed radially with the center at the through-hole, even X-rays entering at shallow angles with respect to the X-ray transmissive window are transmitted through the X-ray transmissive window at a probability equivalent to X-rays entering at deep angles. More X-rays are transmitted through the X-ray transmissive window, and thus the X-ray detector can detect X-rays with high efficiency.

摘要： According to one embodiment, an X-ray tube includes an envelope with an opening, an X-ray transmission assembly mounted on the envelope and vacuum-tightly blocking the opening, a cathode and an anode target. The X-ray transmission assembly includes a window frame, an X-ray transmission window, an X-ray-resistive resin film, a sealing member and a dry gas. The X-ray transmission window is formed of a beryllium thin plate, accommodated in the window frame, and configured to maintain, along with the window frame, a vacuum-tight state inside the envelope. The X-ray-resistive resin film forms a space inside along with the window frame and the X-ray transmission window. The dry gas fills the space.

摘要： An x-ray source comprising a housing, in which a target in the form of an ionized cloud based on metal vapor is provided. The ionized cloud can be excited by means of an electron beam for emitting monochromatic x-rays. The low atom density advantageously produces only a little braking radiation. The robustness of the plasma with respect to the inevitable thermal energy input is also advantageous with respect to the solid target materials. The cloud can be filled at any time with target material which can be vaporized by means of an electric arc. A method for producing x-rays with the above-mentioned x-ray source is also provided. The use of an x-ray source for emitting monochromatic x-rays for x-raying a body is further provided.

摘要： An object of the invention is to provide an X-ray generator having a simple configuration where heat generated in the irradiation window can be prevented from conducting to a desired portion in accordance with the purpose of use, the method of use or the structure of the X-ray tube. In an X-ray generator for releasing X-rays generated by irradiating a target placed in a vacuumed atmosphere within an X-ray tube with an electron beam from an electron source through an irradiation window of the X-ray tube, the irradiation window has thermal anisotropy where the thermal conductivity is different between the direction in which the irradiation window spreads and the direction of the thickness of the irradiation window, and therefore, the thermal conductivity in the direction in which the heat from the irradiation window is desired not to conduct is made relatively smaller.

摘要： A method for inducing chemical reactions using X-ray radiation comprises generating an irradiation volume within the interior of a reaction vessel by introducing X-ray radiation into the volume, in which two or more reactants are introduced. With respect to the two or more reactants and any subsequently created intermediate reactant or reactants, the aggregate extent to which the foregoing reactants are to be ionized to any degree is selectively controlled, and the average degree of ionization in the irradiation volume, from partial to total, of that portion of the foregoing reactants which is to be ionized is selectively controlled, through control of the fluence and energy of the X-ray radiation, to thereby induce selective reactions of reactants to occur in the irradiation volume. One or more reactants may be delivered through a double-walled pipe containing X-ray shielding to prevent their premature irradiation before being injected into the irradiation volume.
