3. 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

4. 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:
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

5. 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)

6. 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?
