Pumping Characteristics and Application of Getter-ion Pump

With the advent of getter-ion pumps, it seems worthwhile to examine its pumping behaviour and effect on the residual gases within glass-metal vacuum system.A titanium getter-ion pump similar to the cold cathode “VacIon” type developed by Hall and the ultra-high vacuum mass spectrometer designed for the study of surface phenomena in ultra-high vacuum were chosen for this purpose.Some pumping characteristics of a getter-ion pump and vacuum phenomena in bakeable glass-metal lsystam evacuated by getter-ion pump at various baking conditions have been investigated.
