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 Slide 13

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 LCLS-II New Instruments Workshops, March 19-22, 2012 Slide 14
