Experimental Facilities Division (XFD)

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

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

Two-phase installation FEE installation plan Two-phase installation Phase 1 Solid Attenuators Gas Attenuator Calorimeter Beam Direction Slit Gas Detectors K-Mono 5 mm collimator Direct Imager (Scintillator) FEL Offset Mirror Systems Phase 2

FEE installation details Phase 1 includes all X-ray diagnostics Most items shipped to SLAC from LLNL, being installed Most wiring done, about to begin testing First beam by end of May Phase 2 includes mirrors Install most component in May Beam-alignment cameras installed in late June

LCLS Offset Mirror Systems 800-2000 eV to Hutch 1 HOMS: Hard x-ray Offset Mirror System SOMS: Soft x-ray Offset Mirror System insertable 800-2000 eV to Hutch 2 Shadow Wall Wall 2 insertable 2000-25000 eV to Hutch 3-6

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

XFD began 2009 with some staff in place XFD staffing XFD began 2009 with some staff in place J. Schneider, J. Hastings, J. Arthur (upper management) H. Tompkins (NEH Area Manager) P. Stefan, S. Moeller (diagnostics physicists) N. van Bakel (detector physicist) J. Bozek (AMO scientist) D. Fritz, A. Robert, S. Boutet, Y. Feng (LUSI scientists) Matrix support from Laser group, Controls group, DAQ group, Rad Physics A total of about 20 people equal to 12 FTE

New staff supporting XFD early operations XFD staffing New staff supporting XFD early operations Z. Van Hoover (XFD Safety Officer) J. Bringetto (XFD Documentation Specialist) H. Kamil (LCLS User Admin) C. Bostedt (AMO scientist) D. Rich, J-C Castagna, M. Holmes (operations engineers) Coming soon, needed for AMO commissioning Floor Coordinators (interviewing now, 5 to be hired) Coming soon, not essential for AMO commissioning Additional technicians Administrator Additional scientists

New XFD Operations Structure Strong ties between XFD and ASD ASD operating structure used as a model for XFD Preparing key processes and documentation XFD directives: describe roles/responsibilities and prescribed actions XFD training plan and training records plan SAD, ASE to include NEH Instrument Readiness Review (IRR) process for adding capability to LCLS experimental area incrementally

Timeline to approval for experimental ops May Install FEE instrumentation Hire remaining staff, prepare processes and documentation June X-rays in FEE, commission diagnostics Install AMO instrument Prepare for ARR Accelerator Readiness Review June 30 Validate operational readiness process, including IRR process July Instrument Readiness Review for Hutch 1 and AMO instrument Resolve any final issues X-rays to AMO, begin instrument commissioning

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

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 supports one added User Administrator

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

LCLS User Program: Important dates First proposal round close 9/1/2008 (AMO only) 2nd proposal round close 5/15/2009 (AMO, SXR) 3rd proposal round close ~10/1/2009 (AMO, SXR, XPP)

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 try diffraction imaging of molecules or clusters

Summary XFD is a new department at SLAC, will run LCLS X-ray experimental facilities XFD and ASD are working together to operate LCLS XFD will be the interface between LCLS and the world user community XFD is staffing up and preparing a structure for safe, efficient operations
