Abstract:
1. A vacuum enclosure defined by a wall having inner and outer surfaces, the inner surface in contact with the vacuum and the outer surface in contact with ambient air, wherein the vacuum enclosure includes therein a getter for at least hydrogen and water vapor, the getter comprising a substrate and deposited thereon, by vacuum deposition, a thin-layer laminate including at least one layer (α) of substance(s) selected from the group consisting of platinum group metals and oxides thereof, and at least one porous hydrophilic layer (β), the porous hydrophilic layer comprising a mixture of at least one active metal with at least one active metal oxide, wherein the at least one layer (α) is deposited on the substrate, and the at least one layer (β) is deposited on the at least one layer (α), wherein the at least one porous hydrophilic layer (β) is in contact with the vacuum, and wherein the vacuum-deposited mixture is formed by evaporating at least one active metal in an inert atmosphere at a pressure of between about 0.1 and 1 Pa, into which oxygen has been introduced at a pressure from about one to two orders of magnitude less than the inert atmosphere pressure.
