Abstract

In this unit, the heating power for the ionization gauge filament is supplied by an audio amplifier fed from an internal oscillator. Stabilization of the electron current, for wide variations in the emissive characteristics of the filament, is achieved by a negative feedback loop which controls the gain of the amplifier.
