    Abstract: An x-ray tube assembly (16) includes a housing (40) and an insert frame (52) supported within the housing (40), such that the insert frame (52) defines a substantially evacuated envelope in which cathode (56) and anode (54) assemblies operate to produce x-rays. An x-ray transmissive window assembly (70) extends between and in a fluid-tight relationship with the housing (40) and the insert frame (52). The window assembly (70) includes an insert window (72) brazed to the insert frame (52), a top plate (76), which is connected to and substantially surrounded by a flange (78), where the flange (78) is fastened to the x-ray tube housing (40). An annular side plate (86) is connected to a fluid-tight relationship with both the insert frame/window interface (74) and the flange (78). The window assembly (70) cools the window through enhanced heat transfer while preventing housing coolant from contacting the insert window (72), thereby eliminating coolant carbonization on the window (72) and enhancing x-ray beam quality.

    Abstract: A window that provides good structural integrity and a very high capacity for removal of the heat deposited by x-rays, electrons, or ions, with minimum attenuation of the desired beam. The window is cooled by providing microchannels therein through which a coolant is pumped. For example, the window may be made of silicon with etched microchannels therein and covered by a silicon member. A window made of silicon with a total thickness of 520 .mu.m transmits 96% of the x-rays at an energy of 60 keV, and the transmission is higher than 90% for higher energy photons.

    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: 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.

    Abstract: The present invention relates to a radiation generating apparatus which includes an envelope provided with a first window through which radiation is transmitted, a radiation tube housed in the envelope and provided with a second window through which the radiation is transmitted, the second window being located at a position opposite the first window, and an insulating fluid adapted to fill the space between the inner wall of the envelope and the radiation tube. Plural plates are arranged side by side between the first window including its periphery and the second window including its periphery, and overlapping one another with gaps between them. The gaps are formed among the plates, and thereby the withstanding voltage between the first window and second window is made larger.
