David Schultz LCLS-II Deputy Project Director
March 19, 2012
Outline
Slide 2
• Project priorities and status • Key features • Project overview & layout • Project schedule and path forward
LCLS-II New Instruments Workshops, March 19-22, 2012
LCLS-II Project Priorities
• Build a highly productive scientific user facility Maximize technical capabilities for the longer-
range future • Simultaneous SXR and HXR operation • Experiment hall capacity • Undulator hall length
• Control the Project Cost/Schedule DOE Guidance is $405M Total Project Cost Formal Project completion (CD-4) in 2019
LCLS-II New Instruments Workshops, March 19-22, 2012 Slide 3
• Conceptual Design (CD-1) approval 10/14/11 • Long-lead procurements approval 3/14/12
• Injector system and support facility • Fully funded for FY12 • DOE Preliminary Design (CD-2) Review as early as
August, 2012 • Establish Project baseline schedule and budget
LCLS-II Project Status
LCLS-II New Instruments Workshops, March 19-22, 2012 Slide 4
• Second 120 Hz injector and 1km LINAC section LCLS-1 and LCLS-II operate independently
• Two New Undulator sources with variable gap In a new undulator tunnel Electrons to two undulators in parallel, 60 Hz each Soft (250 - 2,000 eV) Hard (2,000 - 13,000 eV)
New underground experiment hall, two floors

Install Instruments
EH2 complete
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 2018.
