Cryosorption pumping of hydrogen and helium with metals and metal oxides at 4.3 K.
Author(s) : RAO M. G., KNEISEL P., SUSTA J.
Summary
Pressures below 0.1 nano torr can be maintained in large liquid-helium cooled ultra-high vacuum systems by increasing the available active cryosorbing surface area. Clean metal oxides (metal sponges) can provide the required surface area increase for higher adsorption capacities as well as for enhancing the pumping speed at extremely low pressures.
