12. LCLS-II Project Schedule EH2 complete  First Light  Install Instruments LCLS-II New Instruments Workshops, March 19-22, 2012

13. 2012 plans • Start Injector facilities construction in July • Start Injector technical system fabrication • Complete Construction designs by the end of the year. • Develop the Project baseline schedule and budget for presentation to DOE in August. LCLS-II New Instruments Workshops, March 19-22, 2012

14. Summary • LCLS-II will add capacity and capability to the LCLS scientific program, and will provide space for expansion. • To minimize cost and risk, electron systems rely heavily on LCLS-1 designs. • LCLS-II will dovetail with the LUSI-II project. First light in 2018. LCLS-II New Instruments Workshops, March 19-22, 2012
