摘要： A beam limiting apparatus is provided for reducing the amount of off-focus radiation in the image-forming beam emitted from an x-ray tube assembly. The x-ray tube assembly has a housing with an x-ray port for the passage of x-rays therethrough, a mounting boss defining the x-ray port, an x-ray tube mounted within the housing and defining a glass envelope, an anode mounted within the glass envelope, and a cathode spaced relative to the anode within the glass envelope. A peripheral flange of the beam limiting apparatus is mountable to the mounting boss of the x-ray tube housing, and a radiation-absorbing body of the beam limiting apparatus projects downwardly from the peripheral flange through the x-ray port. The radiation-absorbing body is formed of an electrically nonconductive, filled epoxy resin material, and defines a base surface, an x-ray entrance aperture formed through the base surface, an x-ray exit aperture spaced relative to the x-ray entrance aperture, and an x-ray transmissive beam conduit formed between the entrance and exit apertures. An x-ray transmissive window is integrally molded with the radiation-absorbing body and extends across the beam conduit. The base surface of the radiation-absorbing body is spaced closely adjacent to the glass envelope of the x-ray tube and defines a predetermined gap therebetween. The x-ray tube housing also is molded of an electrically non-conductive, radiopaque, filled epoxy resin material, and includes a conductive outer surface formed of a conductive coating.

摘要： The present invention provides a high gain collimator producing generally uniform intensity profiles for use in lithography and other applications. A focusing optic is also provided. The collimator includes a reflector and guide channel. The guide channel preferably includes polycapillary tubes and/or microchannel plates. The polycapillary tubes are used to collimate or focus the central portion of the x-ray beam in a circular, elliptic, square, or rectangular shape. A conical, parabolic resonance reflector or grazing incidence reflector with a shape similar to the polycapillary collimator is used to increase the solid angle collected and produce a circular, square, etc. annular x-ray beam whose inside dimensions are approximately equal to the exit dimensions of the polycapillary collimator. The annular beam shape, intensity profile and collimation angle is adjusted, if necessary, by an absorber, or polycapillary tubes to provide the desired intensity profile at the exit aperture of the hybrid x-ray collimator optic. A focusing optic is obtained by placing two collimating optics end to end.

摘要： A method and apparatus to fabricate nano-device and semiconductor device structures and features by controlling a coherent or near coherent particle beam to directly deposit, or direct write, onto a preselected deposition site of a substrate and into a predetermined shape is provided. Evanescent wave plates are optionally included to increase the order of the particle beam prior to interaction with a photonic lens. The photonic lens is holographically generated by means of a source laser and an optical lens to focus the atomic beam onto the deposition site by means of Lorenz force interaction between light fields of the photonic lens and dipole moments of the atoms of the atomic beam. The diffraction pattern of the optical lens is computer calculated to precisely form the desired photonic lens in accordance with the shape and size of the desired feature or structure to be built on the substrate and the characteristics of the atomic beam, the source laser, the shape and position of the substrate and the location of the deposition site.
