Abstract:

Results of an experimental investigation conducted to determine the feasibility of using titanium gettering to remove large flows of H2 gas and of combining gettering and cryopumping in a staged pumping system to remove simulated rocket exhaust gases are presented. The staged pumping system about 8 in. in diameter and less than 30 in. long consisted of a 77K cryopumping stage, a 20K cryopumping stage, and a titanium gettering stage with 77K surfaces. High temperature combustion exhaust gas mixtures, with flow rates up to about 0.3 gm sec, were pumped, and a pressure level of about 0.001 torr was maintained.
