Problems relating to physical processes defining operation of pumps with non-sputtered getters: gas adsorption on solid body surface, in particular sorption of hydrogen and other gases by non-sputtered getters; gas diffusion in non-sputtered getter volume; gas solubility in getters involving formation of chemical compounds and solid solutions. Information on design, pumping-out characteristics of the pumps with non-sputtered getters (sorption-diffusion) and pumping-out modular is presented. 46 refs.; 39 figs.; 18 tabs.
