A device for the removal of hydrogen from a vacuum enclosure at cryogenic temperatures and especially high energy particle accelerators

摘要

A device for the removal of hydrogen from a vacuum enclosure of cryogenic temperatures, especially high energy particle accelerators 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 H₂O, preferably powdered aluminium oxide and in contact with palladium oxide which preferably covers, at least partially, the water absorber.
