Abstract

847,320. Cathode ray tubes. ENGLISH ELECTRIC VALVE CO. Ltd. May 6, 1959 [Aug. 29, 1958], No. 27783/58. Class 39(1). The electron multiplier section 7 of an image orthicon tube is provided with a potential surface 8 which is negative with respect to the potential of the field terminating mesh 4 adjacent the target 5 in order to prevent secondary electrons from the mesh from entering the multiplier 7. The surface 8 may be a ring- electrode and is preferably internally connected to the cathode of the gun 6.
