Abstract: An object of the present invention is to provide to an electron beam tube and electron beam extraction window capable of generating high output electron beam by effectively releasing heat generated when an electron beam passes through a window whereby temperature rise of the window is controlled and breakage of the window is prevented. The electron beam tube comprises first projections continuously provided on a first surface of the window, and second projections which are continuously formed on a second surface of the window and are located in positions corresponding to areas between the first projections wherein a projection height of the second projection, a projection width of the second projection and a distance between the adjacent second projections are smaller than those of the first projections, respectively.

Abstract: A modular electron beam device is disclosed, the device being housed in a modular enclosure containing a power supply subsystem coupled to provide power to an electron beam tube. The enclosure is shaped to permit stacking of plural such modular units in a way that the stripe-shaped beam emitted from each of the units completely irradiates a surface to be treated. Beams may lie on different lines but the combined beams sweep out a width on a surface which is a continuous span. In an alternate embodiment of the invention, the modular unit comprises a plurality of electron beam units, each comprising an electron tube and a filament and bias supply to power the tube. A single high voltage stack is common to the plural tube/filament/bias sub-units. A daisy-chain arrangement allows for the single high voltage stack to power all of the tube units. In yet another embodiment, the modular unit comprises a plurality of electron tubes powered by a single power supply.

Abstract: A system for extracting a high power beam from a vacuum in which a beam is generated into atmosphere, which system is formed of: (a) a thin foil window of a material having good heat dissipation properties positioned adjacent the vacuum to permit the beam to pass therethrough; and (b) an air dynamic window between the foil window and the atmosphere. The foil window and air dynamic window are designed such that most of the pressure ratio drop from vacuum to atmosphere is across the foil window and most of the pressure drop in psi is across the air dynamic window.

Abstract: A vacuum tube electron beam device having a thin, single crystal, electron permeable, gas impermeable membrane for electron transmission and methods for making such a device. Single crystal membranes can have small thickness due to high strength, are highly transmissive to free electrons due to that small thickness. The ordered crystalline structure of such membranes provides minimal obstructions to electron beams, and yet is highly impermeable to penetration by gas and liquid molecules. Single crystals are anisotropically etched to precise membrane dimensions, and can also be etched to provide microchannel structures for flowing cooling fluid across the membrane during use. A doped silicon anode 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. A double membrane structure can also have a pressure between the membranes that is between the pressure within the vacuum tube and ambient pressure outside the vacuum tube, allowing the membranes to be thinner. The membrane can also be compressed for increased strength. A number of cooling methods are used to maintain the integrity of the membrane.

Abstract: Apparatus for dispersing a fluent material such as a liquid includes a device for discharging a stream of the fluent material and a device for providing energetic electrons such that the electrons impinge on the fluent material to provide a net negative charge on the fluent material in the discharged stream. The fluent material discharged is dispersed at least partially under the influence of the net negative charge so imparted. The electron-supply device includes a chamber separated from the fluid passageway by an electron-permeable membrane, and may also include an electron gun for generating a beam of energetic electrons such that the electron beam passes through the window and impinges on the fluent material. The electrons may impinge on the fluent material as the fluent material is discharged from the device so that the fluid flow carries the charged portions of the fluent material away from the device. The apparatus may be used to atomize liquids even where the liquids are electrically conductive.

Abstract: A microwave electron accelerator has a very limited range over which pulse beam current can be adjusted without destabilizing the operation of the machine. Therefore, means must be devised to reduce current without seriously reducing energy, or producing unwanted x-rays. One means includes spreading the beam in a scattering foil and subsequently absorbing the outer portion with a blocking wall. In order to make the means adjustable the foil thickness, the size of a passing aperture in the blocking wall or the position of the blocking wall can be adjusted.

Abstract: A method of making an electron permeable window is provided which entails depositing a thin film of an inert, high strength material or compound having a low atomic number onto a substrate by chemical vapor deposition (CVD). Following that deposition, a window pattern and window support perimeter are photolithographically defined and the substrate is etched to leave the desired window structure. For a particular class of materials including SiC, BN, B.sub.4 C, Si.sub.3 N.sub.4, and Al.sub.4 C.sub.3, films are provided which are exceedingly tough and pinhole free, and which exhibit nearly zero internal stress. Furthermore, due to their extreme strength, these materials allow fabrication of extremely thin windows. In addition, because of their low atomic number and density, they have excellent electron penetration characteristics at low beam voltages (15 to 30kV), so that most conventional CRT deflection schemes can be used to direct the beam. Also, such films are remarkably resilient and chemically inert even when very thin and can easily withstand large pressure differences.
