Investigation and Characterization of materials towards building ionization vacuum gauges
Ionization gauge systems are one of the most frequent types of pressure measurement devices used for measuring very low pressures. In theory this type of devices could be used to measure extremely low pressures. However, when working in the lower end of the pressure range the ionization gauges suffe...
