Preserved Fulltext
The performance of an experimental ultra-high vacuum system employing the combination of a sorption pump and a getter-ion pump is described. Measurements done on this system using dry air indicate that the most suitable pressure for switching-on the getter-ion pump is 1•'2•~10-2 mmHg, and for
