An article support is constructed to support an article. The article support includes a back fill structure constructed to supply and extract a thermal buffering fluid to and from the article support. The back fill structure is connected to an extraction duct that is constructed and arranged to extract at least a gas phase of the thermal buffering fluid from the back fill structure. The back fill structure is connected to a supply duct, constructed and arranged to supply a liquid phase of the thermal buffering fluid to the back fill structure. The back fill structure is arranged to have the thermal buffering fluid brought in a combined liquid and gas phase to thermally connect with the article. |
