A combination of a getter and an ion pump.
Notes :
The getter pump is based on the principle that certain materials have the ability to adsorb and absorb certain gas molecules, thereby removing these from the vacuum vessel. This pump is very selective and only certain gases, such as H2, O2, N2 and CO2, can be pumped.
The ion pump has a pumping effect on all gases including the inert gases and is based on the principle that gas molecules are ionized by electrons.Terme :
- ionization getter pump
