Gas Pressure Gauge Based on Alpha-Particle Induced Ion CurrentsThe use of ionization currents for measuring pressure was first demonstrated in the late 1940's. The early gauges operated at high voltages and used rather large ion sources. The ionization gauge is actually a densitometer that is sensitive to the temperature and pressure of the gas in the chamber. This report describes the use of low voltages and small ion sources in the development of a prototype.
