5. Division of responsibility
ASD responsibility
Undulator Hall
XFD responsibility
Near Experimental Hall
Front End Enclosure
Far Experimental Hall

6. Experimental Facilities Division (XFD)
XFD is the administrative home of the LUSI Instrument Scientists

7. Experimental Facilities Division Tasks
Manage safe operations in LCLS experimental areas
Manage LCLS user program
Maintain and upgrade X-ray instrumentation
Enable good user science; initiate in-house research

8. Current XFD Priorities
LCLS Construction: Installation in FEE, Hutch 1
Augment scientific and support staff
Create structure for safe operations
Begin User program
LUSI: Accelerate schedule

9. The LCLS X-ray Beamline
X-ray transport tunnel
Far Experimental Hall
Near Experimental Hall
Front End Enclosure

10. Diagnostics and Offset Mirrors in the FEE Two-phase installation
Solid
Attenuators
Gas Attenuator

11. Phase 1 includes all X-ray diagnostics
FEE installation plan
Phase 1 includes all X-ray diagnostics
Currently shipping to SLAC from LLNL
Installed, wired by late April
First beam by mid May
Phase 2 includes mirrors
Install most component in April
Beam-alignment cameras installed in June

12. LCLS Offset Mirror Systems
eV to Hutch 1
HOMS: Hard x-ray Offset Mirror System
SOMS: Soft x-ray Offset Mirror System
insertable
eV to Hutch 2
insertable
eV to Hutch 3-6

13. The first two LCLS instruments
AMO
Soft X-ray beamline without monochromator, for high-field experiments
Funded by LCLS Construction
Installation June 2009
Commissioning July 2009
SXR
Soft X-ray beamline with monochromator, for materials science
Funded by SXR Consortium
Installation January 2010
Commissioning March 2010

14. Creating Operations Structure
LCLS Organization
Strong ties between XFD and ASD
XFD directives
XFD training plan and documentation
SAD, ASE to include NEH
Key XFD operations staff
Top managers (Safety Officer, Program Manager)
Area managers
Floor Coordinators
Accelerator Readiness Review
mid-late June

15. LCLS X-ray Operations plan
Sept-Dec 2009, with 1 instrument (AMO)
Mar-July 2010, with 2 instruments (AMO, SXR)
Aug-Dec? 2010, with 3 instruments (AMO, SXR, XPP)
2-3 more instruments in 2011
Steady-state X-ray operations at ~4000 hrs/year
Scheduled in blocks of about 6 months, with periodic brief interruptions for machine studies
Typical experiment will last for about 1 week

16. Transition of LUSI instruments to XFD
XFD contributes science guidance to instrument planning
LUSI scientists are matrixed from XFD
Transition from Project to Operations is marked by Instrument Readiness Review
Formal in-house review, includes review of standard operating procedures
XFD manages each instrument in operations phase

17. LCLS User Program
Goal: safe, efficient operation promoting the best science
LCLS will be a DOE-BES User Facility
Access through proposal/review process
LCLS scientific staff frequently collaborate with users, also maintain independent research programs

18. User Program Management
LCLS and SSRL are combining resources, creating a common User Administration Group
Managed by Cathy Knotts
Manages User training, User agreements, User metrics
LCLS is supporting one added User Administrator

19. LCLS Proposal Review Panel (PRP)
PRP members
Christina Back (San Diego) Janos Kirz (LBNL)
Magid Chergui (ETH Lausanne) Dwayne Miller (Toronto)
Lew Cocke (Kansas) Juerg Osterwalder (University of Zuerich)
Gianluca Gregori (Cambridge, UK) Metin Tolan (University of Dortmund)
Chi-Chang Kao (BNL) Kyoshi Ueda (Sendai)
Steve Kevan (Oregon) Edgar Weckert (DESY)
Two representatives of LCLS management without voting rights:
Jerry Hastings Jochen Schneider

20. LCLS User Program: Important dates
First proposal round close 9/1/ (AMO only)
2nd proposal round close 5/15/ (AMO, SXR)
3rd proposal round close ~10/1/2009 (AMO, SXR, XPP)

21. LCLS User Program: First experiments
First proposal round: 28 proposals from 16 countries (>200 scientists)
PRP met in December, gave highest rank to ~10 proposals
Most highly-ranked proposals will study effects of intense X-ray pulses on atoms or simple atomic clusters
Some highly-ranked proposals will study diffraction imaging of molecules or clusters

22. XFD will be the interface between LCLS and the world user community
Summary
XFD is a new department at SLAC, will run LCLS X-ray experimental facilities
Administrative home for LUSI Instrument Scientists
XFD will be the interface between LCLS and the world user community
Responsible for running User program
XFD will nurture creation of LCLS instruments, then manage them
Close ties with LCLS Construction and LUSI projects
Goal: safe, efficient operation promoting the best science
