Abstract: This disclosure provides systems, methods, and apparatus related to graphene. In one aspect, a method includes submerging a frame support in an etching solution that is contained in a container. A growth substrate, a graphene sheet disposed on the growth substrate, and a primary support disposed on the graphene sheet is placed on a surface of the etching solution. The growth substrate is dissolved in the etching solution to leave the graphene sheet and the primary support floating on a surface of the etching solution. The etching solution in the container is replaced with a washing solution. The washing solution is removed from the container so that the graphene sheet becomes disposed on the frame support.

Abstract: An X-ray generator capable of reliably reducing an X-ray focal spot size without depending on the focal spot size of an electron beam on a target. Providing, within the irradiation range of an electron beam B of a target laminated structure 3 comprising a target 2 and an X-ray irradiation window 1, a low X-ray absorptivity region 3a of localized low X-ray absorptivity in the irradiation direction of the electron beam B results in the suppression of emission to the outside of X-rays from among the X-rays generated as a result of the irradiation of the electron beam B onto the target 2 that are from regions other than the low X-ray absorptivity region 3a, and an X-ray focal spot of a size corresponding to the size of the low X-ray absorptivity region 3a is obtained regardless of the size of the irradiation region of the electron beam B.

Abstract: A radiation window foil for an X-ray radiation window comprises a mesh that defines a number of openings (902), said mesh having a first side surface (903) and a second side surface (904). A layer (906) spans said openings. Said layer (906) is on the first side of the mesh but spans said openings at a level closer to the second side surface (904) of the mesh than the first side surface (903) of the mesh.

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: An x-ray window includes a mount with a support frame and an aperture. A window film has a stack of layers including: a thin film layer comprising a material selected from the group consisting of diamond, graphene, diamond-like carbon, beryllium, and combinations thereof; a boron hydride layer; and a polymer layer. The window film, including the thin film layer, the boron hydride layer, and the polymer layer, extends across the aperture and is supported by the support frame. The window film is attached to the support frame, defining a sealed joint. The layers are capable of withstanding a differential pressure of at least 1 atmosphere. The window film is substantially transmissive to x-rays having an energy in the range of 100-20,000 electronvolts.

Abstract: 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.

Abstract: An x-ray tube (24) includes an anode (42) defining a target. A cathode assembly (40) is in operative relationship with the anode to produce x-rays (56). An evacuated envelope (35) encloses the anode and cathode. The evacuated envelope includes a metal frame portion (39). The material comprising the metal frame portion has a backscatter coefficient. An x-ray transmissive window (41) is joined in a vacuum tight manner to the metal frame portion of the evacuated envelope. The material comprising the x-ray transmissive window has a backscatter coefficient. A backscatter layer (90) is deposited on the x-ray transmissive window and the metal frame portion of the evacuated envelope around the x-ray transmissive window. The backscatter layer has a backscatter coefficient greater than the backscatter coefficient of both of the window and the metal frame.

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.
