Abstract: An apparatus is provided for generating X-ray radiation in an outer magnetic field, which may be generated by a magnetic field device. The apparatus includes a cathode configured to generate an electron beam and an anode configured to retard the electrons of the electron beam and generate an X-ray beam. The apparatus further includes a device configured to generate an electric field orientated from the anode in the direction of the cathode and substantially collinear to the outer magnetic field, wherein the cathode, as an electron emitter, includes a cold cathode that passively provides free electrons by field emission.

Abstract: An electrostatic-shutter image tube (10) has a shutter electrode (17) disposed between an electron source (12) and a focusing and accelerating electrode (13). An electron flow is propagated through a network of equipotential lines to form an image on a target (14). The shutter electrode (17) is annular and conforms with an equipotential line. Deflection electrodes (20a,20b) and an image sequencer (21) make it possible to influence the position of a sequence of small images on the target (14) where they are temporarily stored.

Abstract: A position-sensitive radiation detector includes a substrate and an electrically conductive electrode system which is arranged on a surface of said substrate and the configuration and arrangement of which permits position determination of a charge carrier beam impinging thereon. The substrate and the electrode system each consist of a transparent material, for example glass, or a mixture of indium oxide and tin oxide. Disposed on the electrode system is a layer of luminescent material. The present radiation detector permits at the same both an electronic and an optical signal acquisition, the latter for example photographically, visually or by means of an optoelectronic device, such as a video camera, which picks up the light passing through the substrate. Due to the combined electronic and optical signal acquisition the radiation detector can be used in a very large intensity range.

Abstract: A device for directly displaying X-ray images on a phosphor screen of a cathode ray tube by means of a steady cathodoluminescence is arranged such that the excitation of the phosphor screen is controlled by the persistent polarization and depolarization of the phosphor crystals in the phosphor screen by exposure to X-rays. The X-ray images formed on the phosphor screen in the cathode ray tube may be read out by synchronously detecting changes in the electric current of the collecting electrodes of the tube during the scanning of a reading electron beam on the phosphor screen displaying the X-ray images.

Abstract: A method for storing data in an archival memory semiconductor target by providing a masking layer of a conductive material on the surface of an insulative layer upon the top surface of a semiconductor substrate; the material layer is assigned a two-dimensional array of possible data storage sites. The masking layer at those storage sites at which a first binary value is to be stored, is melted; the selected material is one which, at the melting temperature thereof, does not wet the surface of the chosen insulator whereby apertures are formed by the writing electron beam in the masking layer, at energy levels insufficient to evaporate the masking material. The writing beam energy is reduced at the data sites at which data bits of the remaining binary value are to be stored, and does not melt the masking material thereat. The data stored in the target is read by sweeping an electron beam of relatively low energy across the array to induce a flow of current from the semiconductor substrate and of magnitude dependent upon the presence or absence of an aperture in the masking layer at the data site interrogated.

Abstract: An electron beam or other charged particle beam tube of the compound fly's eye type having a coarse deflection system is described. The beam tube comprises an evacuated housing together with an electron gun or other charged particle beam producing means disposed at one end of the evacuated housing for producing a beam of electrons or other charged particles. A coarse deflector, a compound micro lens assembly, and a fine deflector are disposed in the housing in the path of the electron or other charged particle beam for first selecting a lenslet and thereafter finely deflecting an electron or other charged particle beam to a desired spot on a target plane. The electron or other charged particle beam tube is designed in a manner such that the electron or other charged particle beam is caused to diverge at a small angle of divergence in advance of passing through the coarse deflector by appropriately locating the virtual origin or point source of the charged particle a small distance in advance of the coarse deflector.In addition, a dynamic focusing correction potential is supplied to the micro lens assembly along with a high voltage energizing potential with the dynamic focusing correction potential being derived from components of both the coarse deflection potentials and the fine deflection potentials.

Abstract: A color difference between stored and write-through (unstored) information displayed by a direct viewing bistable storage CRT is achieved by admixing the storage phosphor with a second phosphor that emits light of a distinctly different color. The second phosphor is chosen to have a lower relative light output efficiency than the storage phosphor under low voltage, flood gun illumination conditions.
