Abstract: An x-ray generator tube comprises a vacuum chamber with a cathode and an anode, the cathode and anode placed in the vacuum chamber, the cathode emits an electron beam in the direction of the anode, the anode includes a target emitting x-rays when it is struck by the electron beam, and the x-rays propagate out of the vacuum chamber by passing through the wall of the chamber via a diamond-based transmission window. According to the invention, a diamond-based x-ray sensor is integrated into the diamond-based transmission window.

Abstract: 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.

Abstract: 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.

Abstract: An X-ray target and an X-ray generation device including the X-ray target are provided. In an X-ray target, a frame for supporting an irradiation window is divided into a first frame closer to the irradiation window and a second frame on the outer side of the first frame. The irradiation window is formed of a diamond plate having a thermal expansion coefficient of 1×10−6/K. The first frame is formed of Mo (molybdenum) having a thermal expansion coefficient of 4.8×10−6/K or W (tungsten) having a thermal expansion coefficient of 4.3×10−6/K. The second frame is formed of Cu (copper) having a thermal expansion coefficient of 16.5×10−6/K. A difference between the thermal expansion coefficients of the irradiation window and the first frame is less than a difference between the thermal expansion coefficients of the irradiation window and the second frame.

Abstract: 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.
