WP73 Schedule 2012 Start tendering Hard X-ray mono Finish technical design Soft X-ray Mono, start tender Order large scale vacuum parts: pipes, stands, … Start ordering front ends, SASE3 gas attenuator 2013 Receive prototypes: 1 x bimorph mirror, 2 x mirror chamber, 1 x monochromator, Slit-BLMs Launch order for 10 distribution mirrors Order remaining vacuum hardware, collimators Order 8 remaining mirror chambers Order 2-4 more hard X-ray monochromators 2014 Start of Installation SASE1 Receive Soft X-ray mono, hard monos Receive first mirrors … 2015 Continue installation 2016/17 X-ray commissioning + users

Metrology done by Frank Siewert, HZB Strategy for mirrors 52 52 930 9 (max.11) x same base substrate (exception SASE3, M2) 3- 6 (max. 8) bimorph bender (min. M2 of each BL) JTec: Could do two in 2013, accepting request now, 14m delivery for first Zeiss: IBF (up to 1.5 m) becomes available in 2013 Seso, WinlightX, Zeeko et al. are also interested Could divide project in three part: 1. 20 nm PV substrate (many vendors), 2. 2 nm PV deterministic polishing (JTec, Zeiss, ?) 3. Assembling of piezos (only SESO) Metrology done by Frank Siewert, HZB

Strategy for gratings Jobin-Ivon (Horiba) could produce up to 460 mm grating, however only laminar (holographic) HZB (EFRE) will have new grating machine in June 2013 (up to 600 mm, but really 500 mm grating) Only blazed gratings (but 2x intensity, 3x higher damage tolerance) Technological issues: Low pitch is difficult (50l/mm and lower) Our VLS parameters are very small and require high precision Metrology not so clear (but we hired Maurizio Vannoni)

Concluding Remarks Major challenges now: Avoid delays towards end of 2015! Peak of spending in 2013 (procurement, logistics) CAD integration, racks, software become critical now Manpower build-up for installation Major risks: Mirrors and grating can be years too late, if manufacturer cannot do it (on the other hand, huge progress on polishing) Operation may look different than we anticipate today. Is e.g. the development of beam loss monitors really needed?
