Abstract:
The major effort was placed upon the experimental evaluation of the various design approaches and techniques proposed for obtaining a simple, but reliable, tube design meeting the objective specifications of the program. Some preliminary tests were performed in bell-jar vacuum systems, but the major emphasis was placed on experimental glass tube structures which could be properly baked-out and evacuated. Mechanical problems have delayed the full evaluation of the compression-sheath-supported helix structures. The fabrication of interim tubes in which the final design helix structures are supported directly in precision-bore glass are being expedited in order to complete the evaluation of the proposed design for the microwave-amplifier section of the tube. Initial evaluations of the proposed design of the video section have been promising, especially from the viewpoint of the dynode characteristics and dynode life. Experimental metalceramic subassemblies have been made and mechanically evaluated. The techniques being established are being applied initially to the novel video section of the final tube design. The experimental periodic-permanent-magnet focusing structure, which was originally only intended for use with the exploratory glass tubes, was found to be also suitable for use with the prototype tubes.
