Superconducting 1.3 GHz Cavities for European XFEL | |
|
||
| Production of 800 superconducting cavities for XFEL at industry is the largest in the cavity history action. The preparation phase for the European XFEL cavity production was finished 2010. It included a number of activities: qualification of high purity niobium vendors; cavity design; integration of the helium tank and cavity into the fabrication sequence, qualification of preparation sequences, documentation and data transfer, etc. About 50 prototype cavities are produced at the industry, treated and RF-tested at DESY. The XFEL requirements of 23.6 MV/m are fulfilled with a yield of approx. 90%. Production of 600 cavities is currently contracted on principle "build to print" at two companies: Research Instruments in Germany and E. Zanon in Italy. Production has to follow precisely the in detail worked out specifications. Additionally 240 cavities will be allocated end of 2012. DESY procured the cavity superconducting material and 50% of the titanium helium tanks. A new infrastructure for XFEL cavity treatment is created by the contracted companies for cavity production. Qualifications of infrastructure caries out on base of dummy and reference cavities build by vendors. Supervision of the vendors work is executed in collaboration by DESY and INFN (Milano) team. Ca. 50 cavities will be mechanically fabricated and treated at the industry until end of 2012. | ||
