Abstract

The invention relates to an insulated container (11) which can be evacuated and has an application (12) to be cooled, in which insulated container (11) a vacuum can be built up by means of a vacuum pump (22). In order to allow the vacuum pump (22) to be switched off during normal operation, a getter material (26) is arranged in the insulated container and binds gas components which penetrate into the insulated container as a result of unavoidable leakages. The invention provides for the getter material to be accommodated in maintenance areas (20), which can be disconnected by means of valves (21) from the working area (18) which contains the application (12). This allows the getter materials (26) in each maintenance area to be replaced or regenerated, while the operation of the application (12) to be cooled can be maintained owing to the partitioning of the working area (18) from the maintenance area (20).
