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

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.

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.
