Despite the extended use of semicoductor devices in modern electronics, vacuum tubes, especially traveling wave tubes (TWT) still exhibit continuous improvement. In TWT used in satellite links, the efficiency, during the last 10 years has been improved from 40 to 80%. The main influence on the TWT parameters , as well as the life time, has the vacuum inside the tube during the whole time of exploitation. The knowledge about the vacuum changes during processing and exploitation of the tubes makes possible to extend the life time of TWT to 10(5) hours or more. In our presentation we want to give a review of existing microwave tubes, especially TWT, and also the vacuum problems during manufacturing of these tubes in our Institute.
