摘要:
A description is given of the design and operation of a circuit employing gas‐filled tetrodes to maintain constant electron emission in an ionization gauge by controlling the filament temperature. Performance data is given to show that variations in the electron emission due to fluctuations in line voltage or changes in the pressure in the ionization gauge have been to a large extent eliminated. Operating experience with the circuit over a considerable period has shown it to be highly satisfactory.
