After the evacuation, the getter cup is selectively heated with an rf field. The getter material flashes and condenses as a thin, shiny surface on the nearby glass wall. In all production stages, the unfinished tubes are subject to frequent visual inspections. The unsatisfactory units are discarded. Svetlana attempts to indentify faulty tubes as early in the manufacturing process as possible.
Every tube is tested for performance characteristics and visual appearance.
Also the distinguished SV300B will soon be in production. No doubt, more types will follow in the near future. The Svetlana marketing office in California is responsible for the selection of new types for development. The market experts can promptly detect the niche types which are demand worldwide but within the capabilities of the production plant. During recent years, Mr. Pavlov's team has designed over 70 new tubes.
