Abstract
A device for the removal of hydrogen from a vacuum enclosure at cryogenic temperatures, especially high energy particle accelerators which comprises a metal support preferably in the form of a strip of aluminium and a composition able to sorb hydrogen adherent to the support in particular on at least one surface of the strip. The composition comprises a porous absorber of H.sub.2 O, preferably powdered aluminium oxide and in contact with palladium oxide which preferably covers, at least partially, the water absorber.
Claims12
A process for sorbing hydrogen-containing gases in order to create a vacuum essentially consisting of the steps of:
- I. providing a device comprising:
- A. a metal support;
- and
- B. a hydrogen sorbing composition of matter adherent to said support said composition comprising:
- i) a porous physical H.sub.2 O sorbent;
- and
- ii) palladium oxide in contact with said porous physical H.sub.2 O sorbent;
- and then
- II. contacting the hydrogen-containing gasses at cryogenic temperatures with said device.
A device for the sorption of hydrogen-containing gases from a vacuum space apparatus working at cryogenic temperature containing a metal strip having a length greater than its width and having an uppermost surface and lowermost surface a means for operating the device at a cryogenic temperature, and furthermore containing a hydrogen sorbing composition adherent to said strip wherein said composition is a binary composition consisting essentially of:
- i) a porous physical H.sub.2 O sorbing material;
- and
- ii) palladium oxide in contact with said H.sub.2 O sorbing material under i).
A process for the adsorption of hydrogen-containing gases in order to create a vacuum essentially consisting of the steps of:
