The production of cavities and couplers for the European XFEL strengthens RI's position as the world leader in manufacturing key components for superconducting RF accelerators

In 2010 RI was contracted by DESY to deliver 300 elliptical 1.3 GHz cavities for the European XFEL project. The contract includes mechanical manufacturing of the cavities, the surface preparation for the cold RF test, and the joining of the helium tanks.

An upgrade of the RI infrastructure includes a 150 sqm clean room of class ISO 4 for cavity surface preparation, modern electron beam welding facilities and a 800 ¬įC furnace for vacuum heat treatment of niobium cavities . This enlarges our surface treatment capacity for delivery rates of up to 6 cavities per week.

The XFEL coupler production of in total 670 pcs was won by RI in a consortium with Thales Electron Devices (TED). These couplers will be delivered under vacuum, clean, and ready for RF conditioning to the customer LAL (France), which also involves assembly procedures in our ISO 4 clean rooms.
