15 Testing of SRF cavities requires specific infrastructure and expertise Infrastructure for testing in industry is limited Expertise is available in Industry On this background the infrastructure available in Institutes is used in cooperation with the Institutes by industrial experts for tests: Examples: CORNELL: 500 MHz Test-Infrastructure for Synchrotron cavities (Taiwan LS, CLS, DIAMOND) is used by ACCEL DESY: TESLA test infrastructure for testing cavities for BESSY-FEL and 4GLS is provided for ACCEL JLAB and ANL currently provide test infrastructure for AES cavities KEK performs tests for IHEP srf storage ring upgrade supporting MELCO

18 Assembly of SRF cavities/modules is performed in industry on a routine basis There are more Resources existing from recent projects with similar requirements for series production of high quality Components, like the sc magnets for LHC. Manufacturing and asembly space for the LHC Quadripoles

19 Before Taking into Operation we have to deliver Arrival of the 500 MHz Module with accessories at NSSRC in Taiwan

20 Taking into Operation is generally done in close cooperation with the Customer and includes instructions in handling and training of operators

21 Conclusion Industrial Capabilities in SRF technology are available at different levels. We find: Companies focused on engineering with a view to practical application of srf technology Companies offering manufacturing resources (prototyping and series production) Companies offering design, engineering, and manufacturing Companies offering the complete scope from design up to operational training Companies are located in the three regions US, Europe and Asia For ERL projects we believe that the user will find sufficient support in industry from engineering capability, prototyping, up to delivery of turn key systems

22 Future Plans Plans are driven by projects Near term: 4GLS, Peking University FEL, CORNELL-ERL, BNL- Electron Cooler, X-FEL, SNS upgrade, Synchrotrons Far term: RIA, ILC, others (Synchrotrons, linac driven FEL s) Future activities: Provide turn-key modules and Systems Participate in and contribute to development issues (Cavities, Couplers, HOM dampers/absorbers ), provide prototypes, investigate reduction of manufacturing costs Support project preparation with studies for large scale series production Build up capacities and facilities for series production

23 Future Plans Participate in and contribute to development issues (Couplers, HOM dampers ), provide prototypes, reduce costs Example: SNS Beam Tubes: Produced from ONE sheet thus avoiding in total 12 welds per cavity

24 Future Plans Support project preparation with studies for large scale series production Study on cavity preparation and module integration for 20,000 cavities (1999, 2 companies) Study manufacturing of 20,000 Cavities (1999, 2 companies) Study on manufacturing logistics and costs for 500/1000 cavities (internal, graduate thesis) Study on Assembly of Modules for X-FEL ( ) Study on prototyping and series production of 500/1000 Power Couplers for X-FEL ( )

25 Future Plans Build up capacities and facilities for series production We are ready to build up or extend our resources for future projects. However this investment will only be economic if it is based on realistic projects/orders. Timing is of great importance!
