• 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

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.
