Abstract:
A device for maintaining a vacuum in a thermally insulating jacket is described. The device comprises a container formed of a gas-tight material, preferably aluminum, which has an opening to the atmosphere. Inside the container is a first pellet comprising a powder of a Ba-Li alloy getter material. Arranged above, and completely covering, the first pellet is a second pellet comprising a powder of a drying material, optionally including the oxide of a noble metal and a material to prevent contraction of the drier. A process for manufacturing such a device is also described in which the first pellet is obtained by compression of its constituent powders at a pressure between about 30 bar and 1000 bar.
