Abstract
919,298. Electron beam apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 17, 1961 [Aug. 22, 1960], No. 28991/60. Class 39 (1). In a method of zone melting material by electron beam bombardment the specimen 4, Fig. 1, as shown in rod form and circular or polygonal in cross-section, is surrounded by a plurality of, e.g. three, electron guns 8, 9 all at the same level, and either the specimen is moved upwards or the electron beams are deflected to traverse the melting zone from the bottom to the top of the specimen. Opposite the guns are water-cooled shields 12. The beams are line focused beams or spot focused beams which are oscillated horizontally to provide the equivalent of line focusing. The gun shown has a horizontal filament 8, anode 9, focusing coil 10 and the beam entry duct 7 is cooled by water-cooled tubing 11. In Fig. 3 where the specimen is a plate 16 and the beams are deflected by coils 25, the guns 19, 20 are mounted in a separately evacuated chamber 23. Specification 872,579 is referred to.
