TITANIUM GETTERING OF CHEMICALLY INACTIVE GASES BY MEANS OF IONIZATION,
Abstract
The report deals with an exploratory experimental study of gas ionization to enhance the removal of chemically inert gases from a titanium getter pump. Gas ionization was accomplished in the free-molecule region by bombardment of the gas molecules with the electrons of a diode current where the anode was specially designed to produce a high density region of ionizing electrons. The pumping speeds for argon, methane, and helium were experimentally measured. The dependence of ion pumping speed on the rate of titanium evaporation was observed and is discussed in terms of the mechanism of ion removal. (Author)
