    Abstract: An electron exit window foil (106) for an electron beam emitter (100) having an electron beam generator (103) and operating in a corrosive environment (P1). The electron exit window foil (106) has a sandwich structure with an outer side arranged to face the corrosive environment (P1) and an inner side arranged to face the electron beam generator (103). The sandwich structure comprises, as seen from the outer side to the inner side, a protective layer, for protecting the sandwich structure from the corrosive environment (P1), a supporting layer made of Ti, for providing structural support for the sandwich structure, and a thermally conductive layer made of Al, for conveying heat from the sandwich structure.

    Abstract: A vacuum tube electron beam device (15) includes a thin single crystal, electron permeable, gas impermeable membrane (20) for electron transmission. The single crystal membrane may include a small thickness due to high strength, and is highly transmissive to free the electrons due to the small thickness. The ordered crystalline structure of such membrane provides minimal obstructions to electron beams, and yet is highly impermeable to penetration by gas and liquid molecules. A doped silicon anode (19) can provide support for the membrane with matching thermal expansion characteristics, and a crystalline anode can be integral with the membrane. A double membrane embodiment confines the cooling fluid so that it passes close to both membranes.

    Abstract: An exit window (15) can include an exit window foil (12), and a support grid (13) contacting and supporting the exit window foil. The support grid can have first and second grids (16, 18), each having respective first and second grid portions (16c, 18c) that are positioned in an alignment and thermally isolated from each other, The first and second grid portions can each have a series of apertures (16a, 18a) that are aligned for allowing the passage of a beam (14) therethrough to reach and pass through the exit window foil (12). The second grid portion (18c) can contact the exit window foil. The first grid portion (16c) can mask the second grid portion (18c) and the exit window foil (12) from heat caused by the beam striking the first grid portion (16e).

    Abstract: The present disclosure is directed, in part, to a method for fabricating a low-stress, ultra-thin membrane as well as the low-stress, ultra-thin membrane formed by this method. The method includes: layering a first layer on a semiconductor substrate; etching a hole in the first layer; layering a second layer on the membrane of the first layer and over the hole; and etching the substrate beginning from the bottom surface thereof, such that at least a portion of the substrate aligned with the hole in the first layer is removed. The first and second layers are made of substantially the same material, which will usually be silicon nitride, however, it is contemplated that other dielectric materials could be used, but it is preferred that the second layer has an amorphous structure. It is preferred that the second layer be formed with a slightly bubble-shape to help deflect stresses on the second layer. Generally, low pressure chemical vapor deposition will be used to create at least the first and second layers. As a result of this basic method, the second layer has an ultra-thin thickness. Among other devices, the ultra-thin membrane is useful in a device for detecting physical characteristics of a sample bombarded with electrons. In such a device, the ultra-thin, low-stress membrane is positioned adjacent a electron detector. The device may further include an evacuated chamber at least partially bounded by the ultra-thin low-stress membrane.
