Реферат: 1463892 Cathode-ray tubes; permanent magnets THOMSON-CSF 25 Jan 1974 [26 Jan 1973] 03681/74 Headings H1D and H1P A discharge tube, e.g. a camera tube employing a scanning electron beam, has a permanent magnet focusing arrangement which includes a stack of coaxial, frustoconical, contacting, ring magnets, all diverging in the same direction, and all axially magnetized in the same sense. The preferred arrangement, Fig. 6, is formed of two half stacks, the conical surfaces pointing outwardly, and all the magnets being magnetized in the same sense. The ring magnets may be of plastics or elastomeric material filled with a ferrite powder.
