Fermilab is in the process of building the necessary infrastructure to fabricate, process, treat and test superconducting RF cavities for ILC R&D. So far these new facilities consist of a Vertical Test Stand, Horizontal Test Stand, Cryomodule Assembly Facility and ILC Test Area. The Vertical Test Stand and Horizontal Test Stand will be used to qualify cavities for ILC R&D. Inside the Crymodule Assembly Facility, which actually consists of two separate buildings, scientists will dress qualified cavities and string them together in a clean room environment.
These strings of cavities then become fully assembled cryomodules, which will get tested in the ILC Test Area.
