12. Mickaël LACROIX (LAL)ILC-HiGrade Scientific and Annual Meeting 12 IN2P3 Les deux infinis ILC HiGrade WP7 couplers ILC HiGrade cost  Global cost of ILC HiGrade couplers:  Manufacturing cost (Thalès RI)  30 x XFEL coupler manufacturing = 30 x 25 000 = 750 000€  Conditioning cost (LAL)  30 x coupler conditioning = 30 x ? = ? €  Tooling for delivery  15 x 5000 = 75 000€ (if the delivery is done before the end of XFEL production) Tooling ~ 5000€ per pair

13. Mickaël LACROIX (LAL)ILC-HiGrade Scientific and Annual Meeting 13 IN2P3 Les deux infinis ILC HiGrade WP7 couplers Questions & Conclusion  Does anybody need couplers in ILC Higrade project? CHECHIA? CryHoLab? …?  If it is the case, we would like to know :  Location  schedule  Packaging of delivery  If it is not the case, could we use them like :  Ordinary XFEL couplers mounted on cryomodule?  XFEL coupler spares ?  Or any LAL R&D ?  All of that will define the ILC Higrade coupler :  Delivery schedule  Payment schedule  budget needed for 2011
