Abstract
Un dispositivo per eliminare l'idrogeno da una camera a vuoto, a temperature criogeniche, specialmente in acceleratori di particelle ad alta energia, comprende un supporto metallico costituito preferibilmente da una striscia di alluminio ed una composizione atta ad assorbire idrogeno, aderente a detto supporto, in particolare ad almeno una superficie di detta striscia. Tale composizione comprende un adsorbitore poroso di H2O, preferibilmente ossido di alluminio in polvere e, in contatto con esso, ossido di palladio che preferibilmente copre, almeno parzialmente, detto adsorbitore di H2O.
