European industries potential capabilities on superconducting RF accelerator modules

European Industry has been supporting accelerator projects in the past and will be supporting future projects. Larger numbers of superconducting accelerator modules with guaranteed performance parameters have been supplied for example for LEP at CERN and superconducting cavities have been supplied also with guarantees for CEBAF at Jefferson Lab, the proton linear accelerator for the Spallation Neutron Source, Oak Ridge, and for the rf system for LHC. A significant number of cavities have been supplied in support of the TTF/ILC activities. With a view to the future European X-FEL linear accelerator it is expected that turn-key accelerator modules will be requested from industry. A review of the European Industries supplies in the past and present will be given to show their capabilities for the future ILC.
