2. Introduction: origin & goal MYRRHA accelerator risk evaluation list of critical elements: –RFQ in CW mode (4-vane or 4-rod) –... OECD review (MIRT, 2009) request to SCKCEN of showing relevant accelerator activity need for reliability test platform need for innovation platform Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 2

3. Test platform overview Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 3 to be located at the Centre de Ressources du Cyclotron, UCL Louvain-la- Neuve, Belgium

4. Components design & construction modalities –collaborative MAX Collaboration research institutes: IPNO, LPSC, IAP, CRC, Soleil industries: Pantechnik, NTG, Cosylab, IBA,... research consultants (MoU): Spiral2, CERN,... private consultants: Linac Dynamics,... –strong MAX involvement: WP1 and WP2 partners CNRS CEA IAP KULAK SCKCEN Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 4 RFQ@UCL is also an "accelerator consortium test platform"

6. Components LEBT IPNO, benchmarking & error analysis by Linac Dynamics, realisation and commissioning by LPSC, controls by Cosylab Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 6

7. Benchmarking Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 7

8. Components RFQ IAP Frankfurt, benchmarking (3D fields) by KULAK and Linac Dynamics, manufacturing by NTG, tuning at IAP Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 8

9. Benchmarking Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 9

10. Components Diagnostics: low energy, high current –beam current interceptive: FC non-interceptive: BCT –beam position –beam profiles –emittances –longitudinal bunch properties likely to be based on existing items –Spiral2 –Linac4 Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 10

11. Components Power RF for RFQ: 176.1 MHz, 160 kW CW –TH781 tetrode based final amplifier –SS amplifier, Soleil technology efficiency modularity for reliability Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 11

12. Components Controls –main target: be representative of full-size system distant 3-tier EPICS low level with PLC's (slow) + FPGA cards in crates (fast) will include timing –Cosylab for architecture and realisation –test platform! LLRF –discussion with IPNO ongoing –looking for elegant integration Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 12

13. Components Services: –750 kVA –profiting from CRC infrastructure –elec cabinets with remote diagnostics and controls –PLC-controlled cooling system deionized water loop chilled and temperature stabilized deinonized water loop air cooling loop –integrated industrial procurement –test case for integration in EPICS system Dirk Vandeplassche, MAX International Design Review, Brussels, 12-13 November, 2012 13

14. Conclusion setup at UCL/CRC has a high potential as a test platform: –4-rod CW RFQ evaluation –beam characterisation –long reliability runs –innovation target date "first beam end of 2014" is still achievable possible extension with CH cavities (IAP) SC-CH?
