Abstract
The characteristics of screened-grid tubes are discussed and the influence of secondary emission is emphasized. The marked change in secondary emission with surface contamination causes instability of characteristics. Experiments with carefully evacuated ′24 tubes indicate that the evaporation of active material from the cathode considerably increases the secondary emission from the plate and that the liberation of “getter” in a completed tube limits the stability attainable.
