    Abstract: A data reduction system for real time monitoring of radiation machinery measures the bremsstrahlung flux produced by the electron beam used to generate the desired radiation, and then corrects the measurement by corrective signals derived from the determination of other parameters, such as the energy of the electrons, the velocity of the product irradiated, the temperature of the device which measures the flux, and differences in sensitivity between a plurality of devices which measure the spacial and temporal distribution of the flux.

    Abstract: An electron beam exit window, known as Lenard window, has a beam exit opening which is closed in a vacuum-tight manner by a metal foil. Resting on the metal foil on the vacuum side is a supporting grid of heat-proof fiber bundles. The supporting grid is fixed in a frame. The electron beam exit window is particularly suitable for relatively low electron energies with a high power density of the electron beam. This provides an easily manufactured window with low absorption.

    Abstract: An electron tube having a hole or "window" covered by a thin, electron permeable membrane is provided with means for minimizing stress concentration in the membrane adjacent the periphery of the hole, thereby relieving stress concentrations which would otherwise occur when the membrane is forced inwardly into the hole by atmospheric or other pressure on the exterior of the tube. In a manufacturing method, a polymeric ring may be provided between the membrane and the exterior wall of the tube. The polymeric ring, desirably a polyimide has a glass transition temperature less than the elevated temperature used to expel volatile materials from the interior of the tube. The polymeric ring substantially relieves stresses induced by differential thermal expansion or contraction at temperatures between the glass transition temperature and the elevated temperature, as during cooling following the volatile removal step.

    Abstract: A method for irradiating a workpiece, such as a strand, by charged particle, e.g. electron, bombardment is in accordance with the following steps:generating a charged particle beam at one end of an elongated vacuum chamber by thermionic emission from an elongated emitter,accelerating the ribbon beam toward a longitudinally extending, radially curved window member, such as a tube, extending tranversely across another end of the vacuum chamber, the window tube having a length related to the width of the ribbon beams,dynamically deflecting the ribbon beam periodically back and forth to define a sweep field which contains the curved window member therein in accordance with a common predetermined deflection driving signal,dynamically converging the deflected ribbon beam onto the active area of the curved window in consonance with the deflection of the beam, in accordance with a predetermined convergence driving signal phase related to the deflection driving signal, so that the ribbon beam sweeps continuously and substantially perpendicularly over substantially the entire active area of the window, and drawing the workpiece to be irradiated through a passageway defined adjacent to the active area of the window tube as the ribbon beams sweep over the active area, thereby to cause charged particle bombardment of the workpiece. A particle beam irradiator, preferably implemented as a coaxial electron ribbon beam and its irradiation method form aspects of the present invention.

    Abstract: The electron gun comprises an ionization chamber, adjacent to a high voltage chamber. In the wall common the both chambers provision is made for an extraction grid. On the opposite side, the ionization chamber comprises an outlet window for the electrons similar in shape to the extraction grid, and accompanied by a fine metallic foil. The high voltage chamber comprises a cathode brought to a high negative voltage. By giving the two grids the shape of similar parallel strips, a masking effect and a focusing effect are obtained at one and the same time which allows the efficiency of the electron gun to be increased.

One enclosure wall has at least two rows of windows arranged in staggered manner parallel to the scanned lines and respectively sealed by conductive plates, which are transparent to the electrons. The printer also includes plates or coils for deflecting the beam so that the beam alternately scans each row of windows during the displacement of the medium.

    Abstract: A system for scanning a beam of charged-particles across a target is described which compensates for energy dispersion in the beam. A time-varying magnet with circular pole pieces is used to sweep the beam left to right. Two wedge-shaped magnet dipoles, one on each side of the center line are used to bend the beam parallel to the center line and compensate for beam energy dispersion.

    Abstract: Apparatus and method for producing a plurienergetic electron beam source. The apparatus includes a housing which functions as an anode, the same having an electron emission window covered by an electron-transparent grid, a cathode body mounted within the housing and electrically isolated therefrom, the spacing between the cathode body and grid being sufficient to permit a gas discharge to be maintained between them having a plasma region substantially thinner than the cathode sheath region. The method involves the simultaneous feeding of gas between a cathode body and an anode grid, applying voltages of about 10 kV to 20 kV and regulating the gas feed rate and the voltage to maintain a discharge condition of the character described above.
