Abstract

669,414. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. April 12, 1949 [April 23, 1948], No. 9892/49. Class 39 (i). A storage tube with an insulating storage target and a collector electrode for secondary electrons emitted therefrom during scanning, has the latter disposed between the target and the deflecting electrodes and another electrode disposed between the collector electrode and the target for directing the secondary electrons. A tube comprises a cathode 12, apertured grid 14, anode 16 and deflector plates 18, 20. The target 30 has a metal plate 32, e.g. aluminium, supporting a dielectric layer 34, e.g. mica, silicon dioxide, titanium dioxide or alumina. A mesh 36 having a secondary emission coefficient of unity, e.g. stainless steel coated with gold, is mounted in front of the target and is connected to the signal-plate. The collector electrode for the secondary electrons emitted by the target is an open-ended cylinder 28, and wall coatings 40, 42 focus the electrons thereon. Apertures shield electrodes 24, 26, 44 are provided, shield 26 maintaining axial symmetry of the electron lens and shielding the collector 28 from the signal of the deflection plates 20.
